I’ve got a bit of catch-up to do on some field trips. I went to look at the herons at Conant Brook on May 5. It was a raw day and if there were any birds on the nests they were well-hunkered down. I did see a few female mergansers – I suspect hooded because I see the males there, but I did not get them in binocs. Also heard black-and-white warbler, pine warbler, and yellow-rumped warbler.
I then made a quick stop at nearby Dean’s Pond. There were chipping sparrows in the parking lot, as usual, and a cardinal. Also heard a yellow-rumped warbler here.
