Anchiornis: Prehistoric Animal of the Week

Anchiornis huxleyi was a small, feathered dinosaur that lived in what is now China during the Jurassic period a little over 160 million years ago.  It's genus name translates to "Near Bird" in reference to its striking similarity to birds.  Its species name honors Thomas Henry Huxley who was one of the first scientists to propose birds and (other)dinosaurs were related.

Anchiornis was tiny.  In fact, it may be the smallest non-avian dinosaur known to date.  From head to tail it was only about a foot long, roughly the same size as a pigeon.  It probably ate small animals like lizards and insects when alive but I wouldn't be surprised if it ate some plant material as well.  Anchiornis would have co-existed with its close relative, Eosinopteryx

 Like birds, thanks some beautifully preserved fossils, we know that Anchiornis was fully feathered.  And by fully feathered I mean it was fully feathered.  In fact, Anchiornis had more plumage on its body than most modern birds do!  In addition to all the regular body parts one would expect to find feathers on an animal such as this, Anchiornis also had feathers covering most of its face, long, primary feathers running all down each of its legs and it even had small feathers covering its feet and toes.  As strange as this sounds, its actually not unheard of in the modern bird world either.  Owls, for instance, have light, wispy feathers on their toes growing out from between their scales.  Certain breeds of domestic chicken and dove also have primary feathers on their legs and feet.  What Anchiornis used its interesting plumage for is uncertain.  The feathers themselves weren't the right shape for flying, despite having so many.  Because they were all down its legs and feet, running on the ground would have also been a huge hassle for this dinosaur.  It is likely that Anchiornis was mostly arboreal and possibly was able to glide or parachute short distances when it had to.

Anchiornis is one of the few dinosaurs in which the feathers have preserved so nicely, that paleontologists can look at them under a microscope and actually tell what color they probably were in life (which I have written all about before on here).  They can do this thanks to the fact that tiny cells, called melanosomes, preserved.  The shape of the cells reflects the color of the structure that they are on.  All the scientists had to do was look at the shapes of the melanosomes on Anchiornis and then find a match to melanosomes on modern birds.  What they found out was that Anchiornis would have been mostly a dark gray/black on most of its body, had white wing and leg feathers with black tips and had a reddish brown crest and flecks on its head.  Keep in mind the real colors of this animal when alive may not be exactly this since there could have been other cells that have since rotted away over the past 160 million years that when added to the ones that were observed could have given off a different pigment in life.  For now, however, this is our most likely image of the animal. 

That's all for this week!  Not sure if I will be able to get a post up Thursday because I will likely be packing for Gary and I's big trip to New Mexico to take part in an excavation of Triassic dinosaur fossils!  We will be sure to keep you posted though.  As always feel free to comment below or on our facebook page.

Rough Sketches to Finished Paintings: Part 2

Everyone seemed to really like the post showcasing some of the early drafts of my paintings I put up a few weeks ago so I decided to do another one.  Its a good thing I scan these things as I go along sometimes!

This sketch was actually done a few years ago but wasn't used for an actual painting until last month.  I originally wanted to do a painting of a Pachycephalosaurus and was playing around with some poses.  This is one sketch I made that I particularly liked but ultimately ended up ditching.


A few years later I wanted to do the newly discovered Acrotholus for a Prehistoric Animal of the Week and finally used this old sketch's pose.  The result was pretty nice I think.  I think Pachycephalosaurids are particularly interesting when viewed facing the viewer.  Its something about the unusual shape of their heads and how the dome makes a sort of roof over the eyes.



Next is a sketch of the large pterosaur, Ornithocheirus for another Prehistoric Animal of the Week.  Paleontologist, Mark Witton, was kind enough to serve as a source of professional input for me as I was making it.  Here is the initial sketch I showed him.


Awesomely, he said it was mostly good!  Just two things looked off.  1) the individual on the left's wing membrane was incorrectly folded.  It should hug the frame of the arm and finger more.  2) The flying individual on the right's body was too large (Ornithocheirus and its relatives had proportionally tiny bodies).  So then I showed him this with the modifications.



That's better!  Then I went on to add the paint and ultimately produced the painting below.  Some people mentioned to me that they weren't fans of the black color scheme for these guys.  I actually specifically wanted to do a large pterosaur in black for a while at that point and am pleased with how it came out regardless.  Its based on a living animal, actually.  Can you guess what it is?



I also did the spiky dinosaur, Kentrosaurus for a Prehistoric Animal of the Week.  Paleontologist, Heinrich Mallison, was helping me out with the accuracy of the drawing this time.  Here is the first sketch I showed him.


Not bad but there were a few changes that needed to be made.  The tail on the real animal would not have been able to twist in the way that I drew it and the last pair of spikes should be moved to the very tip of the tail.  Also he suggested moving the spikes on the shoulders to the hips.  It is unknown where those spikes attached on Kentrosaurus for certain since the bones were scattered when discovered.  One school of thought is on the shoulders, where they do indeed fit quite nicely but only if they are angled downwards which doesn't make much sense from a defensive standpoint since this animal's enemies would have been taller theropods attacking from above.  Despite this, Kentrosaurus is often reconstructed this way for some reason.   The other idea, which Dr. Mallison supports, is that those spikes were on the hips, facing behind the animal.  They fit there too and it makes more sense as a defensive weapon.  I didn't modify the sketch but instead made a whole new one.


Nice.  Now lets paint!



Last one.  Back in 2011 I decided that I really wanted to do a painting of a Triceratops baby and parent viewed close up.  This is the original idea from my sketchbook.


Here is the painting itself partially done.


And the final product.  This is one of my favorites that I have ever done.  It is also one of the few paintings that I actually sold the original of.  Since then I only sell or gift prints. 


That's all for this week!  As always feel free to comment below or on the facebook page

Camarasaurus: Prehistoric Animal of the Week

This week we are taking a look at probably the most well documented and studied sauropod dinosaur, CamarasaurusCamarasaurus was a long-necked, plant eating dinosaur that lived in what is now the western United States during the Late Jurassic Period, about 150 million years ago.  There are currently four different species within the genus Camarasaurus according to experts.  The largest species, Camarasaurus supremus, measured about sixty feet long.  The species that is most well documented with the highest number of specimens, Camarasaurus lentus, was a bit smaller at around fifty feet long.  There is a possibility that C. supremus is actually just a large individual of C. lentus, however.  The other two species, Camarasaurus grandis and Camarasaurus lewisi were both smaller at around forty five feet long.  Camarasaurus as a genus, believe it or not, is actually on the small side considering that some other kinds of sauropods (long-necked dinosaurs) were the largest land animals of all time.  When it was alive, Camarasaurus would have co-existed with many other famous dinosaurs such as Apatosaurus, Diplodocus, Barosaurus, Brachiosaurus, Allosaurus and Stegosaurus.

Life restoration of Camarasaurus lentus by Christopher DiPiazza.

The name, Camarasaurus translates to "chambered reptile" because of the hollow spaces within its vertebrae.  This is a feature common to many dinosaurs which allows the animal to be large but not too heavy.  Some dinosaurs (the birds) even utilized this adaptation to fly.

Unlike some other sauropods, like Apatosaurus and Barosaurus, which had shorter front limbs than hind limbs, or Brachiosaurus which had longer front limbs than hind limbs, the front and back limbs of Camarasaurus were relatively equal in length.  Camarasaurus also had a much shorter snout than many other sauropods, giving its head a very distinctive boxy look.  Many Camarasaurus specimens have been discovered including some nearly complete skeletons.  There have even been multiple skeletons including adults and juveniles discovered in close proximity to each other which suggests that these dinosaurs probably lived in groups.

Join us next week for another prehistoric creature!  As always you are welcome to contact me in the comments below or on our facebook page to suggest a specific animal of your choosing!

Morris Museum "Dino Day" 2013

Back on April 27th the Morris Museum in Morristown, New Jersey, held its annual "Dino Day".  Like past years your friends at Jersey Boys Hunt Dinosaurs were invited to host a table.  I also had the honor of presenting one of my talks on dinosaurs and was even able to bring a few of my live animals from work along!

The reason this post has taken over a month and a half to post is because we wanted to put together a really nice movie for you.  My long time friend, George, edited all of our footage from that day and put something together that is really special.  Check it out!




Now here is a less edited (much less...no editing actually) video showcasing our friend, Ron Maslanka's Hadrosaurus puppet. 


I love that thing.  Did I mention its life-sized?

Finally here are a few photos from that day.

Gather round, kids!  Just try not to step in the dino crap.

Rough Sketches to Finished Paintings

I haven't done an art post in a while.  Lets do an art post!  Often times when I'm in the process of creating a painting I go through a lot of rough ideas first.  Sometimes I get ripped apart critiqued by professionals kind enough to lend me some insight on accuracy and sometimes I'm just not happy with my own ideas.  Today I will show you the early stages of some images that have appeared on Jersey Boys Hunt Dinosaurs in the past.

Lets start with the sketch for the painting that I chose to be the banner of this site featuring Jersey Boy's Hunt Dinosaurs' unofficial mascot, Dryptosaurus as well as Hadrosaurus and an unnamed nodosaur.


I ended up changing a few things including the Hadrosaurus' tail and the angle of the nodosaur.  It more or less remained the same scene, though.


A few years ago I did a painting of my favorite pterosaur, Dimorphodon that was eventually utilized on this site for a Prehistoric Animal of the Week.  Below is the original sketch I had prepared.


Looking back I sometimes wish I would have stuck with this idea honestly.  I ultimately opted for a different angle focusing on one individual with less background.  Below is the final version!


Next up is a painting I did of the small feathered dromaeosaur, Microraptor ambushing a sleeping early bird called Confuciusornis. Below is the initial sketch.


Even though I still think the original idea's angle is more dramatic, I really wanted to show more of Microraptor's wings so I ended up opting for a slightly different angle instead. Below is the final version.  It was featured on on my post about dinosaur feather colors.


This next one gave went through a lot of changes.  Its the painting of Plateosaurus males fighting for mating rights.  I did this piece for when Plateosaurus was featured as a Prehistoric Animal of the Week.  Paleo-artist, Bruce Mohn was kind enough to lend me some constructive criticism along the way.  Below is the first draft.


Not bad but all the dinosaurs in this scene are being viewed from the side. Lets change the angles a bit!


Definitely more dynamic with regards to the poses but lets make the two that are fighting closer like when modern monitor lizards fight.  Also lets make that spectating female in the background not so in a hurry to move on.  These two guys are competing for her attention, after all.  The least she could do is watch!


Almost there.   Why don't we make this fight even more exciting by adding some biting and movement in the legs.  The opportunity to mate is a big deal and a bachelor male needs to give it all he's got!

 
Nice!  Before finally applying paint i decided to go a little easier on the dewlaps, changed the tails so that they didn't all look so swishy, switched the movement in the feet a around and added some plants in the foreground.  Below is the final piece! 

 
One day when during my lunch break at my job at the zoo I decided to take my sketchpad and doodle some of the animals from life.  I noticed that the Greater Rheas sometimes would rest on their foot bones.  It made me think that maybe some extinct dinosaurs could have rested in a similar manner especially since they had long tails to help support them as well.  Here is a sketch i did applying this posture to a Struthiomimus.  


I eventually illustrated Struthiomimus for a Prehistoric Animal of the Week and went forward with this posture all thanks to the Rhea!  


That's all for this week!  As always i would love to hear feedback from you in our comments below or on our facebook page!

Vagaceratops: Prehistoric Animal of the Week

This week we will be taking a look at a strange(then again there were a lot of strange ones) ceratopsid dinosaur which was requested by a fan through last week's post!  Check out Vagaceratops irvinensis!

Life reconstruction of a pair of Vagaceratops irvinensis by Christopher DiPiazza.

Vagaceratops measured fifteen feet long and was alive about 75 million years ago during the Late Cretaceous in what is now Alberta, Canada.  It was very closely related to another ceratopsid dinosaur, Chasmosaurus.  In fact, when it was first discovered in 2001, it was originally lumped into the same genus and was named Chasmosaurus irvinensis.  Then in 2010 it was re-evaluated and given its own genus, Vagaceraops.

Vagaceratops skull at the Canadian Museum of Nature.

 Unlike its relatives like Chasmosaurus, Vagaceratops possessed a relatively shorter and wider frill which was square-shaped.  It also had a row of small horns called epoccipitals around its frill that bent downwards, over the front of the frill across the squared off top.  Vagaceratops had a horn on its nose but strangely enough, no horns over its eyes.  Some believe that Vagaceratops is actually the juvenile form or possibly the female sex of another dinosaur called Kosmoceratops (briefly mentioned on this site before) because they both had odd, downward-facing epoccipitals across the tops of their frills.  In fact, the name "Vagaceratops" translates to "Wandering Horned Face" because of it was discovered so far away from Kosmoceratops (in Utah, USA).

Skull of Kosmoceratops.  I see the connection but long-distance relationships are just so hard!

That's all for this week!  Next week we will be looking at a dinosaur that lived very early on in the Mesozoic and would have given rise to many of the most famous dinosaurs that we know and love.  As always feel free to comment below or on our facebook page.  I love getting feedback and requests from you guys!

Interview with Artist and Author: Katrina van Grouw


We should know by know that birds are living dinosaurs and are every bit as fascinating.  Coming from a background working with living animals, myself I am really excited to share an interview I had with Katrina van Grouw, author of The Unfeathered Bird.  

Katrina van Grouw is a former curator of the ornithological collections at London’s Natural History Museum, a taxidermist, experienced bird bander, successful fine artist and a graduate of the Royal College of Art. She is the author of Birds, a historical retrospective of bird art, published under her maiden name Katrina Cook. The creation of The Unfeathered Bird has been her lifetime’s ambition.  I bought this book and let me say it is amazing!  Anyone remotely interested in birds will enjoy and learn a whole lot from it.  


Question 1: At what age did you become interested in birds?  Were they always a subject of your art?

KV: As far back as I can remember; I was passionate about birds and natural history. I had a whole string of pet birds and other animals. The companion of my early childhood was a much loved pet chicken called Hilda (which grew up to be a cockerel). Later on I reared a jackdaw which used to fly along next to me when I rode my bicycle. And I built up a little ‘museum’ at home, of birds’ wings, skulls, old nests and feathers etc., and used to persuade my mum to take me to the natural history museum at Tring nearby, at least once a week in every school holiday, throughout my entire childhood. (This museum now houses the London Natural History Museum’s ornithology collections, and it was here that I later worked as a curator).
As a 4 year old I was always drawing eagles and vultures. And dogs – I’ve always felt much closer to dogs than to people. Then, as my interest in birdwatching developed, round about the age of 11, I attempted to draw all the birds on the British list. I managed to get about half way before the school art teacher moulded me into believing that ‘real artists don’t draw birds’.
Although this was rather cruel, it was followed by a traditional and rigid early art training, with challenging still life compositions and regular life drawing sessions from a human model which has been to my advantage as a draughtsman.




Question 2: What medium do you most prefer to use for your art?  Any particular reason why?

KV: All the drawings for The Unfeathered Bird are in pencil (I use a B or a 2B, kept very sharp), then were changed digitally into sepia afterwards. Before this, I used to draw large dramatic sea cliffs in graphite, with very small birds and the foam on the water added in white paint. And before this, I was a printmaker, working primarily in drypoint – a type of engraving - on enormous copper plates.
What all these things have in common is their directness, and I guess that says a lot about me. I’ve done lots of paintings over the years, and lots of printmaking in other media, for example etching (where you have to protect the pale areas while you etch the dark bits) and relief printing (where you have to remove the white areas and leave the dark). But none of these media do it for me at all. Much too long-winded and indirect! And colour? - An irritating and unnecessary distraction!

Albatross by Katrina Van Grouw

Question 3: Is there any particular artist who particularly inspired you growing up?  How about today?

KV: Growing up, my tastes were fairly predictable for a young person learning about art history. I went through a Salvador Dali phase (everyone does). Then I was blown away by the Pre-Raphaelites (everyone is). After that period of obligatory technique-worship, I discovered Samuel Palmer who fuelled my passion for the English countryside. I still love Palmer’s work, but prefer the poignancy of the early 20th Century English graphic artists working before and between the Wars: Eric Ravilious and the Nash brothers amongst others.
I’m also a great fan of the symbolist painters and printmakers, Arnold Bocklin, Gustav Moreau, and Odilon Redon, all of whom have something to answer for in my work.
On the natural history front, George Stubbs was, and is, a great shining hero in the sky.
But no-one has had a more profound influence on me than John James Audubon. Not only did The Birds of America inspire my early drypoints of birds during and shortly after college years but, more importantly, the knowledge of Audubon’s long struggle to produce it kept me going throughout the production of The Unfeathered Bird. It was difficult not to see parallels between the two projects. Like mine, Audubon’s idea did not fit squarely into a niche; it was both art and science. He had to fight for it, and believe in it. He worked life-sized, like me. He was uncompromising and pig-headed like me, and put his book before everything and everyone else - like me. Both books took over 20 years to come to fruition. And Audubon had to get his published in England while I had to get mine published in America. Now, I’m definitely not saying I’m on a par with Audubon – but only that – when the odds stacked up against me and I wanted to give it all up and just fall apart – I’d think about what Audubon would do, and carry on.

Question 4: When did you decide to pursue a career in illustration? 

KV: I didn’t! In fact I’ve never really thought of myself as an illustrator at all, and have only illustrated a couple of books other than The Unfeathered Bird.
My first degree was in Fine Art, and that’s how I always saw myself. In my student days ‘illustration’ was a bit of a dirty word – especially as it was widely assumed that if natural history was your subject matter then you were an illustrator; end of story. I had countless arguments with college tutors who thought it their mission to tell me that I’d joined the wrong course! My college friends and I were always seeking a watertight definition of the difference between fine art and illustration. My definition now is that fine art is produced with the intention of selling or exhibiting it in its original state, whereas illustrations are produced primarily for reproduction. Many a work of fine art, reproduced, can serve as an illustration in a suitable context; and many a fine artist would do well to take a look at the skill and draughtsmanship inherent in illustration. When it comes to drawing ability, most illustrators can wipe the floor with today’s fine artists!
But if you’d like to know when I decided to pursue a career in art – well, it was a reluctant choice and I only submitted to it when I realized that I had no hope of anything else, several years after leaving school and unable to get a place on a science course. I’d shown my drawing ability very young, you see, and had been treated like a child prodigy, so I wasn’t qualified to do anything but art. To be honest though, art was actually what I really wanted to do all along (and I’m certainly no scientist) - but I would have preferred to have been allowed to make my own decisions in my own time!

Question 5: You have a degree in Natural History Illustration.  How much of each field (science and art) does this cover?

KV: In fact my first degree (my BA) was in Fine Art, and after this I went on to do a Master’s degree (MA) in Natural History Illustration. Unfortunately, that particular course, at the Royal College of Art, was a bitter disappointment. I’d expected lectures in historical natural history illustration and a vibrant art/science scholarly atmosphere, but there was nothing like this at all. The tutor encouraged field drawing, and arranged for reduced price entry to London Zoo, which is all very good. However, I had been taken on to do a specific project – an illustrated thesis on bird anatomy (really a research degree), which I was left to pursue unsupervised for the entire duration (2 years). The course has now ceased to run.

Question 6: Have you done other illustrations of subjects besides birds? 

KV: Yes, indeed, but they’re not all what you might call illustrations.
When I first became a printmaker and learned to do drypoints, I’d walk for miles along the chalk downs carrying lots of tiny metal plates that I’d engrave onto directly. My subject was the landscape and its archaeological features – chalk figures, burial mounds, standing stones etc. (more about my love affair with the chalk downs in question 12…). I built up quite a collection which I someday intend to publish as a set.
The move back to natural history subjects was a sudden one, when I remembered where my real interest lay, and I was very much inspired by historical natural history illustrations and museum collections. Birds were my primary interest, but I also did a lot of work from botanical subjects and even molluscs.
So, the landscapes turned to birds and, over the years, the birds became smaller and smaller until they were just tiny shapeless specks in the landscape again (though this apparently seamless transition was, in reality, punctuated with soul-wrenching intellectual crises). The large landscape – or rather seascape - drawings were produced in situ; perched on cliff tops overlooking caves or stacks or natural arches.
People have told me that they can see a similarity between the coastal geology drawings and the anatomical work. This pleases me immensely, as in both cases I was endeavouring to convey the underlying structure and solidity: what’s going on underneath.
In terms of proper illustration, I’ve actually done very little (The Unfeathered Bird which I conceived, wrote, and designed myself; and two bird books for other authors) but I did illustrate a book called A Field Guide to the Smaller Moths of South-East Asia for the Natural History Museum way back in 1992. Photographs were used for the colour plates, but I produced 50 or so drawings of the head structure of various species; pin-head size or smaller (the moth heads - not the drawings) and a few resting postures of whole moths.

Question 7: Even though you have no formal scientific training, you eventually became the curator of ornithology at the Museum of Natural History in London.  How did you achieve such an amazing position?  What was it like working there?

KV: That sounds very grand, but I was actually one of a team of five curators, each with a different responsibility for a part of the collections. (In the UK, curators are more like collections managers in the US, i.e. caretakers as opposed to researchers). I was jointly responsible for skins, and had overall responsibility for specimen preparation and repair. We also all received and supervised scientific visitors to our own area, and answered public enquiries, issued loans etc. It was the knowledge I’d gained in my early anatomical investigations many years before, as well as my understanding of moult and ageing as a bird bander that landed me the job, and especially the fact that I knew how to prepare bird study skins.
Much of the job was just like working in any other big institution - meetings about meetings; corporate policies; health & safety legislation etc. etc. But I loved the place, and was proud to be a part of it; it made me feel like a swan, as opposed to the worthless ugly duckling I’d felt before, and there’s not a day that passes when I don’t wish I was still there.

Question 8: You are a qualified bird bander and have travelled all over the globe working with wild birds.  Do you have a favorite experience doing this?  Was there any particular species of bird you were banding most or trying to band?

KV: Bird banding is all about identifying individual birds so that you can study population changes and bird movements with greater accuracy. All data is potentially useful, but specific projects, with a particular aim, are of the greatest scientific value. I’m really not a scientist at all, but I enjoy the detective work involved in getting as much information as possible from a bird in the hand – a single feather can give a vital clue about a bird’s age, for example. So I could contribute to the scientific work of others in my own way.
I initially trained to be a bander because I wanted to take part in expeditions to remote places – not the best reason, I know! My first expedition was 3 months spent in Senegal, West Africa, banding European migrants in their winter quarters and studying the movements of migrants through the Sahel. So although we were surrounded by all sorts of resident African birds that most of us had only seen in books, our target species were actually the common migrants we were used to seeing in England. It was a fantastic trip and I saw some superb wildlife: patas monkeys galloping across the desert; great flocks of queleas swirling in the air like swarms of insects; lakes covered in bird life – flamingos, pelicans, whistling ducks and wading birds of every description; crowned cranes dancing in the desert; a puff adder swimming through a moonlit swamp amongst the roosting birds... It was all the more poignant for me because until then I’d never even been on an aeroplane!

  
Question 9: Have you ever received any negative feedback on any of your work?  How do you respond to that?

KV: Yes; but only from idiots. And I respond very badly!
But seriously – what hurts most is unjust criticism, without good reason – people making negative comments just to make themselves look clever; and criticism which has no foundation. For example, dozens of reviewers have said The Unfeathered Bird is beautifully written, but one person said the writing is weak. For me, the negative impact of that outweighs all the accumulated effect of the positive comments. I worked so hard, for so long, and sacrificed so much for this book, that it hurts to get niggling little criticisms like that.
However, 99.9% of my reviews have been simply glorious – some, deeply moving - and have far, far, exceeded expectations.

Pomarine Skuas by Katrina van Grouw.

 Question 10: Art and illustration is such a diverse field.  It has also changed dramatically within the past decade or so.  What advice would you have to give an aspiring artist today?
Ooh, nice question – can I give two?


KV: 
Piece of advice No. 1:
Draw. Everything. All the time. Keep a sketchbook. But don’t fret and worry about the drawings looking good to others. Let drawing become an exploration; stay focused and full of integrity about the quality of your observation; be your own hardest critic. A sketchbook is for you and you alone.
Piece of advice No. 2:
Don’t be too opposed to the option of taking a day job. I know; there’s a lot of stigma against it – people think you’ve given up, or sold out, or couldn’t make it as an artist. This is bullshit! As long as you continue to make time for artwork, a part time or even a full time job gives you self-esteem, contact with people, daily routine and money. Money’s really important actually. Life is too short to have to steal leftover food or burn the furniture to keep warm (yes, I’ve done both these things). But always remember: when anyone asks you what you do, say that you’re an artist.
And this one’s for anyone; not just artists:
Be careful what you give up. It might be a long time before you manage to get it back.

Question 11: What is your favorite bird?  Did you have a favorite bird when you were a child?

KV: Well I like jackdaws, for obvious reasons, and that may well have been my favourite species as a child. But it’s seabirds, now, that really turn me on. I love everything about them – even (well, probably especially) the smell. And the sound. There’s nothing so wonderful as being perched on a clifftop above a seabird colony when the breeding season is in full swing.
Fulmars are great – I just love it when they vomit on you.
Storm Petrels are simply magical.
Cormorants are cool (our mutual friend Niroot and I decided that I’d be a cormorant if I were a bird).
But my favourite seabirds of all are Frigatebirds. They’re enormous, black, piratical, primitive-looking things, and you can just imagine Pterosaurs when you see them soaring overhead. They’re so exciting to watch, too. They don’t swim; they can barely perch, but they fly like demons! Best seen against a tropical stormy sky, in pursuit of a shining, white, comet-tailed, tropicbird...

Question 12: Do you have any other hobbies or interests (not necessarily ornithology related)?

KV: Hmm, let me see… I like red wine.

I love going to the cinema. My friends are appalled by the intellectual level of the films I like to see. But I don’t want cultural stimulation – I go there to escape, on my own. Meteorological disaster movies, far-fetched archaeological adventure films, science fiction and anything to do with superheroes do very nicely.

But my greatest passion is for long walks in chalk down landscape – especially the stretch of 100 miles or so that runs between Buckinghamshire (where I live), down through Oxfordshire, Berkshire and Wiltshire and is covered at the far end with ancient earthworks: ditches, burial mounts, barrows, hill figures of horses cut into the chalk; standing stones; and odd isolated clumps of trees. I love the feeling of knowing the landscape intimately, as far as the eye can see. I’ll happily disappear up there for days on end with my dog, Feather. Unfortunately I get slightly afraid of sleeping outdoors on my own at night – or more accurately – I’m scared of getting scared. Probably a good thing, on reflection, as it’s the only thing that keeps me from going completely feral.

Question 13: Your book, The Unfeathered Bird, features many amazing illustrations of bird anatomy all illustrated by you.  Was any particular one especially memorable to do?  Did any give you unexpected trouble?

KV: Unexpected trouble? – oh yes! Drawing the skinned birds was unbelievably difficult. They go all floppy and shapeless. I could just have the skinned carcass lying on the table, and re-construct the position mentally, with reference to images of living birds, or I could rig them up with all sorts of wires and threads and things – whatever would keep them in the position I wanted. The pouter pigeon with its crop inflated was unforgettable. We actually ended up pushing a condom down the bird’s throat then blowing it up like a balloon!
The greatest challenge though was drawing skeletons in lifelike postures from bones that were not articulated; the ones in scientific reference collections in natural history museums. The scientists using these collections need to study the articulating surfaces of individual bones, so it’s important that they’re not glued or wired together. I worked out quite a clever solution: I would draw the skeleton of another bird already prepared in the position I wanted, then rub out and re-draw each bone in turn, with reference to the respective bone of the desired species. It works remarkably well, but you have to really know your birds. The Magnificent Frigatebird (my favourite image from the book) was drawn in this way, from a disarticulated skeleton on loan from the Field Museum, Chicago, and modelled from the position of the Tropicbird it’s chasing. As a huge fan of both frigatebirds and tropicbirds (with feathers on), it was important for me to get it right, and do justice to the dynamism and excitement of a real-live aerial pursuit.

Thank you so much Katrina!  Be sure to check out Katrina van Grouw's website and buy her book!  It has quickly become one of my favorites in terms of imagery alone.  Stay tuned for Sunday's Prehistoric Animal of the Week!  Farewell until then!
