In addition to the aforementioned Caspian Tern (photos), I noted the following at Chatfield SP this morning. From the Marina Sandspit had 1 Pectoral Sandpiper, 1 Baird's Sandpiper, 14 Long-billed Dowitchers (flying), 4 Willets (flying), 2 Semipalmated Plovers, a Merlin flying south and 2 Great Egrets flying east.
-- The South Platte Delta area had 1 Baird's, 1 Pectoral, 1 Greater Yellowlegs, 2 Western Sandpipers, 1 Long-billed Dow, 1 Wilson's Snipe, and 1 each Willow, Least and Dusky flycatchers.
The Swim Beach had tight-swimming flocks of migrant Eared Grebes, Ruddy Ducks and American Coots, 1 Common Tern, 1 Osprey, and 1 juv. Peregrine Falcon that was making shallow stoops on various birds sitting on the water, including pelicans and cormorants. These big guys flinched as the falcon jabbed, but it was wasting its time.
There were rather few landbird migrants in the riparian and weedy areas at Chatfield. Of minor interest were three pure white birds that flew in landed along the shore near the Kingfisher parking lot -- Snowy Cotingas? Snow Petrels? Alas, no... 3 pure white Rock Pigeons.
Next I checked Massey Draw below my home in Ken Caryl Valley. [Note: no general public access] Here there were lots of migrants, with particular activity at some Russian olives and in some areas of willows. The best finds were a Baltimore Oriole (HY male?; poor but documentary photos) and a female Hooded Warbler. Also a HY male Red-naped Sapsucker (rare near my home), 3 fly-over Band-tailed Pigeons, 1 W Wood-Pewee, 2 Dusky Flycatchers, 1 or 2 Cassin's Vireos, 2 Warbling Vireos, 6 Red-breasted Nuthatches, 1 Ruby-crowned Kinglet, 3 Gray Catbirds, 2 Orange-crowned Warblers, 1 Yellow Warbler, 3 Audubon's Warblers, 3 Townsend's Warblers, 2 MacGillivray's Warblers, about 40 Wilson's Warblers, 12+ Western Tanagers, 2-3 Black-headed Grosbeaks, and a nice-sized flock of about 28 Bushtits
There was a wide variety of species (22) feeding in the Russian olives, some eating fruit and others seemingly taking insects or other invertebrates amid the fruitful stems.
