Help Fund Golden-crowned Sparrow Research

by Bryce W. Robinson

GCSP-online-01

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.

Light Morph Ferruginous Hawk Plate

by Bryce W. Robinson

 

In my continued practice at illustration and the design of guide book style plates, I took the opportunity of expanding a needed Ferruginous Hawk illustration into a full plate. I focused on a goal to illustrate light morph adult and juveniles perched and in flight, both topside and underside. I’m currently emulating the traditional plate styles you see in contemporary guides, but as I’ve been illustrating I’ve had some ideas that I may try going forward as I attempt to tune in my illustrations.

For polymorphic species such as the Ferruginous Hawk, illustrating the entire spectrum of plumage types is entirely unreasonable if not impossible. Still, I think there are some plumage types that may deserve attention, apart from the classic rusty bodied birds and dark morphs. I’ve seen some interesting individuals, such as dark birds with white streaking on the breast that is reminiscent of dark morph Harlan’s Red-tailed Hawk. I think including these in an informative plate will communicate two things, one being of course some of the stranger possible plumage types but perhaps more importantly the pitfalls of focusing solely on plumage characteristics for identification.

I’ve produced prints of this illustration for purchase, but I’ve limited them to 25. You can find and purchase a print in the shop by clicking here.
