In Delaware, white-eyed vireos are present through the warm months, arriving around March and heading south again by August.

These windows are set by latitude: Delaware sits in the middle part of this species' range, so timing here tracks the continental average closely. In any given year, weather can move the first arrivals by a week or two either way.

Highlighted months are when white-eyed vireos are expected in Delaware. The edges of the window are the interesting weeks — first arrivals and last departures vary most from year to year.

Getting ready before they arrive

The week before March is the time to act. Have feeders cleaned, filled and out by early March — the first white-eyed vireos into Delaware are scouting for reliable food, and a station that's ready early gets added to their route.

Once nesting begins around April, adults switch to protein-rich food for their young and visits to feeders become quick and purposeful. Expect the busiest activity at dawn.
