Suggestion of westbound coastal aggregation on the evening of April 27

Not a big flight, but coastal transect stations clearly show an unusual pattern of more warbler & sparrow calling in the west. See here for link to station locations and comparative calling data from other nights.

Wind direction and speed charts from Weather Underground for April 27. Wind direction was nearly straight from the east at Niagara Falls (upper chart) at 9PM and had tracked to out of the southeast by midnight. The southward shift was more advanced at Rochester (lower chart).

Snapshot of regional wind direction and speed from Windy.com at midnight on the 28th showing the widespread wind from the southeast across the transect region.
