Marston reservoir, Denver

[Tina Jones]

I looked from Bow Mar dr. today, at Marston Reservoir. I could see flying,  3, Bonaparte's Gull, 1, ad. Herring Gull, and at least 80, Ring-billed Gulls.
 
There were about 12 Horned Grebes in the lake, but they were far out, like the Gulls were.  2, Say's Phoebe were on the metal fence[which encloses Marston on the east side].
 
Happy Birding !
