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.

Singing Coastal Cactus Wren Perched on Coastal Cholla

by Bryce W. Robinson

 

 

The Cactus Wren (Campylorhynchus brunneicapillus) is a polytypic wren (Family: Troglodytidae) that occurs in the arid southwest of North America. The species comprises five subspecies (Following Rea and Weaver 1990). Birds on the coast of southern California differ in appearance slightly from interior groups, primarily in being paler on the flanks where they have less rich and warm tones. The taxonomy of this coastal group has been in flux, but it is currently recognized by Clements, Howard & Moore, and others as C. b. sandiegensis.

A few years ago, I had the pleasure of getting to know this species well while working with nesting birds along the I-10 corridor in California. I can still hear their iconic rattle song as they sing atop cholla in the intense heat of the Sonoran desert. Their nests also stick in my memory. Often in dense and formidable cholla, the species construct a tunnel nest out of grass. These are some of my favorite nests I’ve encountered in all of my time in the field.

I had the pleasure of illustrating this bird for silent auction at the Sea and Sage Audubon Society’s annual benefit dinner. Hopefully it generates some funds for them and finds a good home.

California Gnatcatcher – Polioptila californica

by Bryce W. Robinson

FullSizeRender-1

This month I found myself fortunate to have the opportunity of illustrating a “Coastal” California Gnatcatcher (Polioptila californica californica). I was asked to do an illustration for Sea and Sage Audubon in southern California, and I decided to illustrate the California Gnatcatcher because it is perhaps the most pressing avian conservation issue facing southern California.

A few decades of rapid urban development in southern California’s coastal sage scrub habitat has left California Gnatcatcher’s with shrinking suitable habitat and a fragmented range. These pressures have taken their toll on the United State’s only California Gnatcatcher populations, to a point that in 1993 the gnatcatcher received threatened status.

Today it seems that the California Gnatcatcher’s presence and future in the coastal sage scrub is that of small fragmented populations. In essence, the damage has been done, and efforts now focus on preserving what quality habitat is left and ensuring that the small populations remain.

My choice to illustrate this bird was founded on 1. maintaining awareness for the plight of this incredible bird, 2. supporting a feeling of identity for those that live in the area and invoking the California Gnatcatcher as an important part of that identity, and 3. a reminder that these birds act as a symbol for the broad impacts human development has to the ecosystem, a symbol that goes well beyond single species conservation.

Illustrating for the 2015 San Diego Bird Festival

by Bryce W. Robinson

San Deigo Audubon's Bird Festival Flier

I was invited by San Diego Audubon to illustrate their pamphlet art for the 19th annual San Diego Bird Festival in March of 2015. I illustrated the Osprey above, as well as some pencil drawings included in the brochure. Additionally I’ve been invited to lead a bird illustration workshop.

ORNITHOLOGI will also have a booth at the festival, selling artwork and prints. I plan to have a good stock of both originals and prints for sale.

I have a lot of friends in San Diego, of which I’m looking forward to birding with again. I hope to see them at the festival, and make many more new friends as well. I don’t think I’ve ever been so excited for March!
