Tree and barn swallows, Charles River Peninsula, Needham, MA
What a weird day. I avoided going out early because it was windy (gusts up to 40 mph) and cold (40 degrees). Turns out it probably would have been a good warbler day (blue-wing and multiple parulas without even really looking). But every thing seemed disjointed and out of place. Bobolink in the wrong tree; wrong oriole song for that spot.
And a swarm of swallows of the kind you usually don't see until the late summer; more barns than usual.
No sign of the yellow warbler guys. But yellow warbler female was busy pulling fibers from low-lying plants. Happy Mother's Day!
