Audubon guides to birds have been around since 1946. The first guide bearing the National Audubon Society imprint was Audubon Bird Guide; Eastern Land Birds , written by Richard Hooper Pough, and illustrated by Don Eckelberry.

Birding has come a long way since I was a nipper! But one of the most important aspects of these advances in new-age birding is the fact that they have grown hand-in-hand with the almost exponential growth in citizen science. Cornell University has been running a variety of excellent citizen science projects for many years now.

I want to alert you to a recent study (from April) that looks at the plight of bird populations under conditions of climate change in Europe and North America.

Bird communication is a complex and evolving science.

I was going to have something for you this month about the dinosaur-bird thing, but I never got to it. The potpourri covers some interesting bird related science of the last few weeks, and the promise is this: I’ll get to that other stuff soon, I promise! One of the birds most affected by this is Cassin’s Auklets.

In 2007 I was working in a university building that was just begging for bird feeders. This was where I set up my bird feeders, just one at first, then expanding as everyone expressed delight in seeing the Carolina Chickadees, Dark-eyed Juncos, and Downy Woodpeckers. There were no dead birds for weeks. I hoped it was an anomaly.
