Summer Tanager in Central Park (NYC)

This Summer Tanager was highly cooperative in Central Park on May 13th 2007 - seen at eye level multiple times and also on the ground. The bird appeared to be in molt - the uppertail coverts in particular were both a deep red and also not lying flat. Closer inspection of the photos reveals that one central retrix (R1) was fresh and probably still growing, as well as one or two innermost tertials. The rest of the tail feathers were relatively abraded, as you'd expect. I've decided that this is probably a first spring male, from a combination of factors: the deep red of the undertail and uppertail coverts, the replacement of that central retrix (just the one, although conceivably this could be from damage) and the relatively pointed outermost primaries. Most passerines do not replace their flight feathers (incl. tail feathers) in the pre-alternate molt, although apparently this sometimes happens in hatch year birds (as per Pyle - Identification Guide to North American Birds).

Curlew Sandpiper at Heislerville WMA (NJ)


This adult male breeding plumage Curlew Sandpiper was at Heislerville WMA in NJ on May 13th 2007, one of at least three that were at that site in spring 2007. This was one of a series of five Curlew Sandpipers seen in southern NJ in May 2007 - three at Heislerville (1 male, 2 females), and ones at Stone Harbor Point and Brigantine NWR.

Snowy Owl at Piermont Pier (NY)

Returning to Piermont Pier on Wednesday I found the persistent and relatively tame Snowy Owl in an even more accommodating location only 30 yards off the road devouring yet another unlucky Ruddy Duck. This owl showed the somewhat atypical behavior of plucking Ruddy Ducks from the water, apparently using only one talon, and was quite a success at it too.

Ivory Gull at Piermont Pier (NY)


An adult Ivory Gull turned up at Piermont Pier on the Hudson River in NY and on the morning of Feb 26th was pretty cooperative as was the prior celebrity of the area - the Snowy Owl - perhaps an example of the Patagonia Rest Stop effect. The Ivory Gull was feeding on the remnants of a Ruddy Duck that the Snowy Owl had caught. The Ivory Gull however only remained for a couple of days. North American populations of Ivory Gull appear to be in rapid decline (see this article for example) and it is tempting to point the finger at Global Warming given its impact on other Arctic ice-dependent species like the Polar Bear. Increased vagrancy might be an outcome of a fragmenting population, but then this could just be a random vagrant. Preliminary pics, prior to populating the Gallery with the rest of them.
