[cobirds] ...Big birds flying across the sky (Arapahoe and JeffCo) 3/20

...throwing shadows on our eyes... (I nod to Neil Young)

On Mar 20 a few first-of-season big birds passed my way. In Arapahoe an Osprey was hunting for a long time in the area of Bufflehead and Cooley lakes at South Platte Park, with 6 Am. White Pelicans going over, and a Turkey Vulture and some heard-only Sandhill Cranes passed over the vicinity of So. Prince Street in Littleton.

Over in Jefferson, more Sandhill Cranes passed over the hogbacks near Deer Creek, and 3 White-throated Swifts appeared briefly over their usual nesting cliff on the Lyons hogback overlooking Deer Creek. I noticed that their favored nesting and roosting crack has recently partially fallen apart in a rock slide. I still need to compare with my pictures of the crack from last year, but I think it is substantially changed and sheltered areas the swifts used inside the rock face in that spot are now exposed.
