Slaty-backed no, Glaucous-winged yes, @Black Hollow Reservoir, Weld County

[willc...@gmail.com]

Hi All,

While fruitlessly searching for the Slaty-backed Gull reported this morning at Black Hollow Reservoir, Nathan Pieplow and I stumbled upon a Glaucous-winged Gull. Photos should be up on eBird shortly. As mentioned previously, it is hard to view the reservoir, with best viewing from on top of the hill along Weld CR 19. 

Good luck to any who chase the gulls in Weld,
