The other morning I was passing a farm field near my house. It’s a place where I often go birding and as I glanced around I was thinking “maybe there could be a Rough-legged Hawk today”. But I’ve never seen a Rough-legged Hawk here in [...] posted June 25th, 2011; last edited June 25th, 2011 –– David Sibley Thanks to all who donated (and to Audubon California for facilitating), the Sandpiper Information Center at Pak Thale is ready for its grand opening on 26 June!

From the National Snow and Ice Data Center.

Apparently fledging rates [...] posted April 10th, 2008; last edited April 10th, 2008 –– David Sibley Prompted by some good discussion I’ve read on TexBirds and elsewhere: I want to stress the point that the danger to birds is not so much the height of the wall, but more the wide swath of habitat that would be cleared for the wall and service roads. Chachalacas, Pygmy Owls, Green Jays, etc will [...] posted April 7th, 2008; last edited April 7th, 2008 –– David Sibley Revised 8 Apr 2008 – Do something: Write or call Congress.
