Help Fund Golden-crowned Sparrow Research

by Bryce W. Robinson


I had the pleasure of painting one of my favorite sparrows, the Golden-crowned Sparrow (Zonotrichia atricapilla) for someones birthday. Even more, the person to receive this painting studies Golden-crowned Sparrow migration, so it is quite appropriate. Autumn Iverson is working towards a Ph.D. at UC Davis, focused on movement ecology of these sparrows. She plans to outfit sparrows with GPS tags to track seasonal movements and better understand their yearly cycle.

Today, 21 September, is Autumns birthday. Happy Birthday Autumn!

Autumn needs your help to fund her research. She is currently running a fundraising campaign to raise money for the GPS units she will use on the sparrows. Please, consider helping out this research with as little or large of a donation as you see fit. You can find a detailed explanation of her plans, her research, and how to donate at her experiment.com funding page. 


An Illustration of the Accipiters of North America – The Sharp-shinned Hawk, Cooper’s Hawk, and Northern Goshawk.

I continue to illustrate raptors in flight with the genus Accipiter. Accipiter is a rather diverse genus worldwide, with some beautiful variation from large to small. I look forward to the opportunity of illustrating each species sometime down the road. For now, it was a pleasure to create an image of the three Accipiters of North America – the Sharp-shinned Hawk (Accipiter striatus), Cooper’s Hawk (Accipiter cooperi), and Northern Goshawk (Accipiter gentilis). All have rather broad wings and a long tail, but subtle differences between each help create their own unique shape. Although each are unique, correctly identifying an accipiter in the field is a challenge. A focus on multiple characteristics of an in-flight bird apart from plumage details (that are often difficult to see) will allow a correct identification. These characteristics include flight style, wing shape, head projection, tail shape at base and at tip, and others.

I’ve been illustrating raptors in flight for some years now, which really took off when I met Jerry Liguori. Jerry took me under his wing, so to speak, and filled my head with everything he himself has learned over his many years studying the identification of raptors, particularly in flight. His tutelage accelerated my skills and knowledge in raptor identification, and I can confidently say that without his selfless teaching, my illustrations wouldn’t be the same.

I’m currently focused on tuning in my raptors in flight. I am about to start some large illustration projects focused on these taxa, so I am working to develop my technique and process as well perfecting relative shape and sizes. It’s a challenge, because illustrating each correctly involves so much more than the obvious differences in plumage. What makes each unique are shape, proportion, and posture. I’ve found posture to be the most challenging aspect to capture, since this seemingly simple factor has so much power over whether the bird looks real or not. Furthermore, in flight postures and shapes are influenced by the direction and motion of a bird in that moment in time. For instance, a bird soaring has a unique shape but because of the position of the viewer, that shape may be different for each wing because of the birds posture and how wind or resistance bends the outer primaries. To understand and master this effect is going to take repeated sketching and exploration.

Also, be sure to add Jerry Liguori’s unique guidebooks to your library. Jerry has taken raptor identification to the next level, and his guidebooks are a wealth of information for mastering in-flight identification.
