Wednesday 5/22: Went to Rock Meadow and BBN. Good numbers of warblers including a Blackburnian, at least two Black-billed Cuckoos, and a few other things but my main highlight was a singing Alder Flycatcher, which is Waltham #204.
Thursday 5/23: Wandered to Mt. Auburn eventually. Worked for thrushes in the Dell with minimal success, then took a short wander where I found 2 Turkey Vultures in trees. Also an Indigo Bunting and late-ish Yellow-rump but struck out on the Mourning. Quick trip around the Cambridge Res had 2 Common Loons.
Friday 5/24: Quick loop of Prospect Hill had the adult ravens down near the start of the road, a few warblers (BT Green, Parula, Ovenbird were the most interesting), and 4 Indigo Buntings. Nothing on Cambridge Res or Flint’s Pond. Got a little brighter out, so continued to Great Meadows and had a beaver swimming right below the new platform and first Blue Dashers of the year.
Saturday 5/25: Cruised Cambridge Res, Flint’s Pond, Heard Pond, Purgatory Cove, etc without finding anything.
Sunday 5/26: Tried again for storm-blown birds. Lots of swallows including Bank at Heard and Hardy but nothing else of note.
Monday 5/27: Dunback had lots of the usual breeders (including bluebirds) but the only things resembling migrants were Redstarts. Quick stop at Hanscom got meadowlark and a Broad-wing.
Tuesday 5/28: Harvester at the duck ponds. Very good nighthawk show at Great Meadows at dusk but no Cave Swallow.
