Observation details

**scarce but very regular in this context - continuing SY individual; a rather small-billed bird for WESA but blocky-headed and dumpy-looking overall. Across multiple angles and feeding positions (and in better lighting than our visit on 14 June), this bird seemed more top-heavy and forward-leaning in posture. Also, note the contrast between the brownish coverts and scaps, and some replaced very pale-gray feathers more consistent with WESA than SESA. It should also be noted the regularity of WESA in this context (SY birds over-summering along the south shore inlets), in a phenomenon similar to certain species of rare shorebirds and terns that occur more regularly in this context. This is contrasted by the relative rarity of SY SESAs in this context - possibly attributed to their wintering ecology, ranging much further south in the winter and SY individuals only dispersing a shorter distance northward in summer (vs WESA wintering in the SE US and dispersing to the mid-Atlantic and NE US in summer).
