This bird (2240-12602) was initially banded on 19May 2001,
during our annual bandathon. At that time it was aged as ASY
based on plumage criteria in the "Identification Guide
to No. American Birds (1997)" by Pyle. The PCOVs, RECTs
and Head all indicated an ASY. The bird was recaptured 12
days later by another bander at our MAPS site and again aged
ASY by plumage. We caught the bird for a third time on 14
June 2002 and a third bander aged the bird ASY by plumage.
The PCOVs, Head and Upperparts were indicative of ASY; the
primaries showed extensive wear on P4-P6 of both wings indicating
a possible SY bird, and the SCOVs and Terts, and Underparts
Pyle's Molt section includes "some AHYs occasionally
suspend flight-feather replacement during fall migration".
I assumed that a suspended migration would complete on the
wintering grounds, but perhaps that is not the case. Or on
this bird that is not the case. Hopefully we'll again recapture
this bird, and can further study it.
