Lots of birds have a habit of pumping (or wagging) their tails. It’s mostly open-country birds like phoebes, wagtails and pipits, Palm Warbler, Spotted Sandpiper, and others. Many hypotheses have been suggested to explain why the birds do it, but nobody came up with an answer until Gregory Avellis in 2011. He studied Black Phoebes […]
Cackling Goose is a rare fall migrant through Massachusetts and I usually see a couple of them each fall among the hundreds of Canada Geese around Concord. I look forward to the challenge of sorting through the flocks and picking these birds out, and once a candidate is located the identification has usually been straightforward – […]

I have been noticing variation in American Pipit for many years, and last month I had the opportunity to photograph a small flock. The photos here are of three randomly selected individuals in that flock, all taken within a few minutes on October 27, 2014 in Acton, MA. The differences in color are striking: compare […]
I saw a Cooper’s Hawk catch a Rock Pigeon a few days ago. By itself that experience is noteworthy – a Rock Pigeon is a big bird for a Cooper’s Hawk to handle – but more remarkable was the way the attack unfolded.
My newest print to benefit conservation efforts is this 2014 gouache painting of a Semipalmated Sandpiper with American Avocets (more info about my gouache technique here). This is a common scene in the Mississippi River Delta region, where catfish ponds and other managed wetlands create habitat for large numbers of American Avocets, migrating Semipalmated Sandpipers, […]
I have made prints of this gouache painting of a Northern Saw-whet Owl from 2006 (more info about my gouache technique here). This painting also appeared in a weekly newspaper column “Sibley on Birds”, and the original was auctioned to benefit the Ned Smith Center for Nature and Art. A portion of the sale of each […]
Find the Greater Secondary Coverts These are some of my digiscoped photos from a recent trip to Belize, all taken at the fantastic Black Rock Lodge. On each photo body parts are labeled with letters, and your challenge is to identify the greater secondary coverts on each bird. Good luck!
I have made prints of this gouache painting that I did in 2011 for the cover of the Journal of Raptor Research to highlight a paper on Snowy Owls (more info about my gouache technique here). A portion of the sale of each print will be donated to help fund research, such as the work […]
