[cobirds] Marston Reservoir,Denver County, 4/28/16

Hi all,

Looking at Marston from the East side[Bow Mar Dr.], there was another gorgeous, alternate breeding plumage, Common Loon.  There were 4, Common Mergansers also.


Looking at Marston from the West side, from the fence, birds were more diverse. 4, Semipalmated Plovers,[seems like today was one of their main arrival days along the front range] 1, Killdeer, 2 Least Sandpipers, 4, Long-billed Dowitcher, 1, Willet, and 14, Wilson's Phalarope. The usual Green-winged Teal, and  Gadwall ,were present. Looking out in the middle of the lake from the west side, was a raft of around 32, Western Grebe[no Clark's that I could see], another raft of 30, Lesser Scaup, with 1,  pair of Greater Scaup and 1, pair of Ring-necked Duck.  Close to the Lesser Scaup were around 20, Redhead.


The Swallow numbers were incredible. Many, many , Violet-crowned, and Tree, and Barn, with Violet-crowned being the most common.  At least 1000 , Swallows were present feeding over the lake. Many of the Violet-crowned were trying to stand on the top of Willow stems. They had a hard time balancing themselves on the tippy top of the branches and some were swaying back and forth on the branches and looked like they were about to fall off the the tips, but managed to remain on the branch tips. What a balancing act. This also was seen from the western side next to the Water Board fence.


Happy Birding!!
