Chatfield Sabine's (2) and Ken Caryl Black-and-white 9/21

[David Suddjian]

This morning around 10 am there were two juv. Sabine's Gulls at Chatfield Reservoir. One was on the Platte Arm of the reservoir mostly on the Douglas portion, located around the buoys that are north of the Swim Beach, and while I was looking at that one from the North Boat Launch area (Jefferson) another juv. flew past me close to the shoreline, heading toward the Marina. It passed by as Rock Wrens jeered from the rocks there, for an odd pairing of Sabine's and Rock Wren. There were at least 6 Rock Wrens on the rocks where the road bends around the outside edge of the north launch parking lot. Also noted were an adult Bald Eagle and 6 Yellow-headed Blackbirds (had not seen any of the latter in the local area for quite a while). 

Earlier, a female type Black-and-white Warbler was in riparian near the historic Bradford - Perley House at the north end of Ken Caryl Ranch, Dutch Creek watershed.

Lot's of Brewer's Blackbirds moving south this morning, and congregating at varied spots. Also Am. Robins and Mountain Bluebirds flying south.
