Wednesday 9/14: Purgatory Cove had both Green-winged and Blue-winged Teal but no sandpipers.
Thursday 9/15: BBN before work: lots of Blackpolls, lots of things in awful light. Broad-winged at Prospect Hill at lunch and not much else there.
Friday 9/16: Duck ponds: Ovenbird, Parula, Black-and-white, Yellowthroat, couple more got away. Also big flock of geese overhead. Driving down Lexington St later, single nighthawk over the Wal-Lex.
Saturday 9/17: Started at Dunback. Not quite as busy as I hoped but pretty good with 8 species of warbler including Blackburnian and first of fall BT Blue, several Broad-wings and Sharpies, and Philadelphia and Blue-headed Vireo. Stopped at Cambridge Res on the way home, 2 Greater Yellowlegs, Great Egret, Osprey, Semipalmated Plover, 2 Green Heron. Afternoon walk around Arlington Res failed to turn up the Dickcissel but did get 4 shovelers.
Sunday 9/18: Rock Meadow early: big flock of warblers at the entrance including 2 Parula, Redstart, Blackpoll, Black-and-white, BT Green. Gardens had more BT Green and a couple Lincoln’s Sparrows. Looped around, finding a Coyote and not much else. Return trip through the gardens found more Parula, Red-eyed Vireos, and Indigo Bunting. River Walk was quiet (Kingfisher, Spotted Sandpiper) but 4 Pectoral Sandpipers at Purgatory Cove were new for me in Waltham (195). Also a few Semipalmated, Least, and Spotted Sandpipers, 3 Green Herons, and a single Blue-winged Teal. (And most likely a Rusty Blackbird that I skipped over as brownish grackle, oops).
Monday 9/19: Prospect Hill had nothing beyond a big flock of grackles.
Tuesday 9/20: Hardy Pond in the rain, still swifts and swallows.
