by Bryce W. Robinson

ADFG Conservation Stamp - GOEA 2019-01

Support the conservation of Alaska’s wildlife through the purchase of the 2019 Alaska Department of Fish & Game Conservation Stamp!

I had the pleasure of creating this years conservation stamp, highlighting one of Alaska’s most important avian predators, the Golden Eagle (Aquila chrysaetos). Biologists with ADF&G, such as Travis Booms, are currently working on research that aims to learn more about Alaska’s eagle populations and the threats they face, to ensure that this captivating species remains a fixture of Alaska’s wilderness.

American Ornithological Society Conference 2019 Logo

by Bryce W. Robinson

AOS2019-Logo-draft I-01

I am privileged to share the logo that I created for the American Ornithological Society’s 2019 conference. The logo features three Bar-tailed Godwit (Limosa lapponica baueri), a flagship bird for Alaska and a focal species for some of Alaska’s most influential ornithologists.

I worked closely with the conference planning chair, Colleen Handel of the USGS Alaska Science Center. We created a logo that ties in closely with the theme of the meeting – Birds on the Edge: Dynamic Boundaries. Colleen is part of a team of researchers headed by her husband, Robert E. Gill (also of USGS), that are responsible for discovering the incredible, sometimes 9 day non-stop flight of Alaska’s Bar-tailed Godwits as they return to Alaska from their wintering grounds in southeast Australia and New Zealand (see Gill et al. 2008). As such, one can see why the species is a great choice to celebrate the AOS meeting being held in Anchorage.

Illustrating the Harpy Eagle

by Bryce W. Robinson

Untitled-3-01.jpgOver the past few years I’ve had the opportunity to illustrate the Harpy Eagle (Harpia harpyja), with the cover art for the Raptor Research Foundation‘s Journal of Raptor Research, and private commission work. Recently, I’ve focused again on the Harpy for a large and exciting project I’ve started with The Peregrine Fund (Stay tuned for details), and I’ll soon be returning to the species for Costa Rica focused work that I’ve also undertaken. I hope you enjoy the products of these upcoming endeavors as much as I’ll enjoy creating them.

Prints highlighting some of these Harpy Eagle images can be found in the shop.

Differentiating Adult and Juvenile Gyrfalcon (Falco rusticolus)

by Bryce W. Robinson

Gyrfalcon_Plate-01

Given that much of my career has been focused on the world’s largest falcon, the Gyrfalcon, I often get questions about their life history and Identification. A recurring question is the age of individuals that are observed in winter. Most often, folks ask about juvenile vs. adult, so I decided to make available a simple illustration with annotations as a reference for those with these questions.

What I’ve realized is that fleshy parts confuse a lot of people, since an adult should have yellow legs and cere, whereas a juvenile should have blue. However, it takes female birds much longer to change (well into their second year), and the coloration is also influenced by individual quality and hormones. Some adults, particularly females, tend to be quite dull in the winter (compare this with observations of gull legs in winter, e.g. California Gull). Adults that are likely three years or older (given presence of retained feathers in the upper wing, etc.) can have surprisingly dull legs that may appear blue under certain conditions. The key then is to take a step back and focus on the plumage, since in most cases it is quite straight forward.

The illustration above aims to highlight the key points for aging a Gyrfalcon between adult and juvenile. Eventually I’d like to visually describe more micro-aging factors, but for now I think this will be a helpful resource for those more unfamiliar with this species.

Please, feel free to send me feedback and suggestions. Constructive criticism is always welcome.
