A few more from last weekend: Blackburnian Warbler, Bay-breasted Warbler, Spotted Sandpiper, Mottled Duck.
My state has lifted the shelter in place order, so I suppose from here on out I am disqualified (yes?) from contributing to the North American list, but I've had a mind to keep tallying anything seen on foot from home. I'll continue to post them at least, and I'll have them in case we collectively decide to transform this into a "green" list as suggested.
Bobolink was a nice yard list addition this morning, a little flyover flock.
