Orange-breasted Falcon (Falco deiroleucus) Painting: A Mile Marker

by Bryce W. Robinson

Untitled-2-01

I feel really fortunate for the opportunity to illustrate and paint during the six months I’ve spent in Central America. My time here has really expanded my understanding of birdlife, and strengthened all of my skills with which I employ to communicate this understanding to others. I’ve been a bit more familiar with the Orange-breasted Falcon each time I’ve painted it, and on reflection I think it shows in each painting. This has taught me the value of studying structure, plumage, posture, effects of light, and personality in each species I illustrate. Being familiar with your subject (from field study) is integral to rendering it correctly, which means I’ll need to spend more time in the field looking at birds.

Just Published in Avian Conservation and Ecology: Nest Box Use During the Non-breeding Season

by Bryce W. Robinson

Caitlin just published an excellent paper detailing nest box use in the non-breeding season in Idaho.

This publication is an important contribution because it discusses patterns in nest box use during a period that has received little attention. Additionally, because nest box programs are engineered to supplement natural cavities to saturate an area with nesting habitat geared to benefit species, a full understanding of its impacts throughout the yearly cycle is important. This paper not only reports how nest boxes are used in the non-breeding season, but illustrates some possible negative impacts as well. Such impacts are primarily associated with the variable thermodynamic nature of nest boxes relative to natural cavities, resulting in deaths at temperature extremes.

The paper also details some inter and intraspecific interactions in nest boxes, and patterns of use in other cavity roosting species such as the Northern Flicker and European Starling. With this discussion comes supplementary video of some such encounters, and excellent inclusion to add further context.

Just Published: Applied Raptor Ecology: Essentials from Gyrfalcon Research

by Bryce W. Robinson

The Peregrine Fund just released a new book, “Applied Raptor Ecology: Essentials from Gyrfalcon Research”. This book serves as a techniques manual geared towards providing early career researchers with information and a stepwise guide for conducting various research on raptors. This information is also supplemented by mock data, and R code to help the researcher begin to form skills in R and analysis.

Although I am the clown in orange on the cover, my true contribution is found inside the book. I contributed as an author of a chapter – Quantifying Diet; an appendix – Guidelines for Conducting a Camera Study of Nesting Raptors; and as coauthor of an appendix – A Photographic and Morphometric Guide to Aging Gyrfalcon Nestlings.

*PDF’s of each chapter will be available January 2018

Published in Western Birds: First Record of Eastern Phoebe Breeding in Alaska

by Bryce W. Robinson

My latest publication, and my first in the excellent regional journal Western Birds (Western Field Ornithologist’s), details the first documentation of successful breeding of Eastern Phoebe in Alaska. You can find the pdf on my Researchgate profile. It’s short and to the point, and worth a read for anyone interested in the birdlife of North America.

Last year, while working in Alaska with the US Fish and Wildlife Service’s Migratory Bird Program, I caught word of an Eastern Phoebe documented near Nome. I’m very familiar with Nome, since it is where I studied the Gyrfalcon for my master’s degree. I’ve birded the area heavily in the spring and summer months. There aren’t many Eastern Phoebe records for the state, so a bird showing up in Nome on the western coast is that much more exciting. I planned to be in Nome the following month to work with Red Knots, so I crossed my fingers that the bird would stick around long enough for me to see.

Surprisingly, a second Eastern Phoebe was documented soon after. Then came documentation of nest building, followed by nesting behavior and ultimately confirmed egg-laying and incubation. On my arrival at the start of July, I joined my friend Lucas DeCicco to see the pair on the outskirts of Nome. Since July is a time when the flow of birders ebbs in Nome, no one had checked on the nest for some time.

Sure enough, we found the birds feeding nestlings. After we had photographed and observed, Luke and I resolved to return regularly to document the success or failure of the pair.

In the end, the pair was successful. It was the first documented case of the species successfully breeding in Alaska, and on top of that in a location quite inhospitable and atypical of the species. The coast of Nome is not known for mild weather.

I told Luke that I thought it important to document this novel event in a publication, and he agreed. So we resolved to report the record, and asked for the help of those that originally found the first phoebe in June.

Thanks to Luke for his help with this seemingly simple publication. It wouldn’t be so clear, simple, and clean without him. Also, a big thanks to my co-authors who first found these birds – Aaron Bowman, Scott Hauser, John Wright. Thanks for the help with cleaning up the publication, and of course documenting the birds that led to this record.
