large shorebirds, Boulder Reservoir (Boulder County)

[David Dowell]

This morning, there was a nice assortment of shorebirds on the northwest side of Boulder Reservoir (that is, the muddy delta accessible from the trailhead near the bend in 55th):

Long-Billed Curlew (2)

Marbled Godwit (8)

White-Faced Ibis (16)

Greater yellowlegs, lesser yellowlegs, Franklin's gulls (many), Bonaparte's gulls, ring-billed gulls, and California gulls were also in the same area, along with typical duck species.

Like Mike Henwood, I have also seen mixed flocks of western and mountain bluebirds, with large numbers of the latter, in multiple locations.  The other bird I've seen in large numbers is Wilson's Snipe:  11 at Boulder Reservoir, 8 at Clover Basin Reservoir, and 26 at Golden Ponds.

After reviewing photos, I think one of the ibises was actually a GLOSSY IBIS (observed late morning on Tuesday, April 16).  It had a dark iris and face lacking a white border, and it had darker legs than the white-faced ibises.  All ibises were adults in breeding plumage.
