Not to present too provocative of an opinion, but there may be an argument
that this bird is a Eurasian Curlew.  The second photo shows significant
barring in the secondaries extending into the inner primaries.  This
feature is absent in both “European” and “Eurasian” Whimbrel, which show a
clean demarcation between the secondaries and primaries, with the primaries
being darker and only slightly barred on the inner webs of the innermost
feathers.  This is depicted in figures 9 and 10 on p. 110 of O’Brien,
Crossley, and Karlson.

However, this feature is obvious in Eurasian Curlew as drawn in Svensson
and Grant.  A quick Google image search shows the characteristic as well.
Perhaps birders with greater palearctic experience could corroborate this
conclusion.

While O’Brien et al refers to European Whimbrel as a spring vagrant to the
east coast and Eurasian Curlew as a fall visitor, records are sporadic
enough that no trend is obvious.  In addition, on eBird most Eurasian
Curlew records from the Massachusetts/New York area appear to be from the
late winter-early spring time frame.

Depending on one’s perspective, the sole verbal description of the bird as
having a “...long curved bill...” could be seen as additional support for
Curlew, as compared with the relatively shorter curved bill of Whimbrel.
However, lacking further description by the observer including body
coloration, structure, underwing pattern, and vocalizations, neither
species can be conclusively supported IMO.
