Very good. Only a matter of time that one was found with all the swift watching
nowadays.
Tough to id swifts in silhouette but it can be done. Proportions look very good
for chimney and too long-winged for Vaux's relative to body length. Even though
more of a long shot, would be good to eliminate other tropical swifts. Seems to
be a Chaetura by shape and amount of head projection, but white-chinned and
spot-fronted swifts can appear very similar to chimneys in silhouette. Swifts
are super tough to nail down! Even great looks in good light can leave
lingering doubt.
Cheers
Doug
