Still no Blue-winged Teal! Now I am on the lookout for Green Heron. Every year right around this date I get a Black-and-white Warbler in Millbury. Today was no different. Same spot 3 years in a row for me. Always "early". Yesterday I was able to photograph a very cooperative Blue-headed Vireo! I have never seen them so low in the trees before. There were 2 birds chasing each other all over the place constantly! Hopefully some rarities will show up. I need to head to Bolton Flats tomorrow to see if any shorebirds came in.
