The enigmatic and charismatic Spoon-billed Sandpiper may be headed for extinction according to a Bird Life International report. The population estimate, never more than a few thousand pairs, has recently plummeted to only 200 to 300 breeding pairs. The reasons for these losses are complex, involving changes to habitat during migration and loss of breeding

A fascinating story of two flamingos, one from the Yucatan that provides a very rare undisputed US record of a wild bird, and another from the Old World (via a Kansas zoo) that shows how widely an escaped bird can wander. Details and a great comparison photo are on the Louisiana Ornithological Society website

In my previous post about Siberian birds I made a tenuous connection between an above-average season for vagrants in the Bering Sea and a few vagrants farther south and east. Updates from Gambell by Paul Lehman show a continued surge of Siberian birds, highlighted by North America’s first Sedge Warbler, and even more of the

An Op-Ed in today’s New York Times by Vaclav Havel makes reference to the larger issues of consumption and the environment. He minimizes the debate over climate change, saying that whether it is primarily human-caused or not action is important, and there are other equally serious anthropogenic issues which are simply Nature’s response to the

Update 24 Sep 2007: Seen on the 22nd was Gambell’s 3rd Siberian Accentor, 4th Dusky Warbler, and 6th Little Bunting of the season; while St Paul, Pribilofs turned up their 2nd Siberian Accentor and first Pechora Pipit of the season. And the big news, adding some weight to my tenuous connection – a Common Rosefinch

Here’s a neat tool from American Public Radio – an educational game that calculates your global ecological footprint. Overconsumption is at the core of virtually all environmental problems, and most of that consumption is stuff that we don’t even think about. Especially in the fast-paced world of the US middle class, we do things the
I’ve thought more about the “square-peg-in-round-hole” analogy in my previous post, and made a few simple drawings to expand that analogy. In many ways, bird identification is like a matching game. The observed bird (here in black) must be identified by matching it to illustrations in a diagnostic key (the gray shapes here). This is

Last week I had the pleasure of spending four days birding at Barrow, Alaska, working on an eider identification project with the US Fish and Wildlife Service. While there I was able to study hundreds of Greater White-fronted Geese that were grazing on the tundra – surprisingly numerous and surprisingly approachable. I’ll write a separate

Another note from the comments under Sandwich Tern by Joseph Kennedy on 4 September, this deserves a separate discussion (Thanks, Joseph). He writes: I have received a note Stu Wilson concerning the black tern pictures posted from the same date. I guess that I should check feet on the rest of my tern pictures. According

In an interesting 4 September comment under the Sandwich Tern bill color discussion, Joseph Kennedy presents a photo of a juvenile Royal Tern with partly yellow-orange legs. Compared to one of his photos of juvenile Sandwich with yellow legs, the Royal appears to have brighter leg color. Presumably that is variable, but it would be
