South Beach, Chatham, Massachusetts: 21 June, 2012
The following three images are of a basic-plumaged Bar-tailed Godwit of the nominate (European) form present on South Beach, Chatham, MA on 121 June 2012. All images were taken with a Canon 40D and Canon 100-400mm lens and are extensively cropped (the bird was very wary and difficult to approach). This presumably is the same bird present a couple weeks previously (6-9 June) on Tuckernuck Island off Nantucket (the fourth image below).
Note the outer two primaries are worn and very faded with
prominent white shafts (very conspicuous in flight). Note also the Black-bellied
Plover has just begun its primary molt (the innermost primaries have been shed).
The state of molt (and drab coloration) indicates that both birds are in their
second calendar year (i.e., about a year old).
The following image is of the Tuckernuck bird present 6-9 June
(image taken by Richard Veit who found the bird); it certainly looks like the
A flight shot of the South Beach bird taken on 21 July 2012 showing that the
bird has begun molting its primaries (the innermost four have been shed and some
new inner primary coverts have appeared).
