Observation details

*Rare; juveniles (although one more advanced in terms of molt than the first; more below) seen well and photographed foraging on the flats at the S end of the island. Long, decurved bill; big-headed and "chesty" appearance; pale breast; and bright rufous upper scaps (really only present in one of the birds) all noted. The more advanced bird mentioned above was originally called an adult in the field, but review of photos has shown an apparent contrast between the scapulars (which it appears to be in the midst of replacing) and coverts (one slightly more advanced in its molt timing than the other individual), which points to a juvenile. Furthermore, I'd expect an adult WESA at this time of year to retain at least a few of its flank and belly spots and to appear slightly less pale-chested, which this bird does not. Faded rufous upper scapulars bordered by a thin buffy line and light buff on the breast are also visible in at least one of the images as well. Photos 1091 and 1111 are of the 'classic' juvenile and the rest are of the 'advanced' juvenile.
