Hello all, Yesterday myself and Jim Merritt (fully vaccinated) did some birding in Otero County and nearby areas. Both Holbrook Reservoir and Horse Creek Reservoir are very low right now with excellent shorebird habitat, although Horse Creek is still deep enough it has some diving ducks on it

I should add since it has since been brought to my attention, that it is John Drummond who first found and tentatively identified this individual. So thanks to John Drummond's sharp eye for this great El Paso County species. Cheers, David On Thursday, April 15, 2021 at 9:54:33 PM UTC-6 David

Hello all, I'm generally slow to get invested in local identification challenges and only do so if there is an ongoing situation and/or questionable validations in eBird that are brought to my attention. In essence, it is with some hesitation that I bring bad news to Colorado listing,

Hey Max, Indeed it appears you found two Lesser Black-backed Gulls; a near adult 4th cycle bird (notice the fleck of black in the bill for age) and a 2nd cycle. Lesser Black-backed Gulls have contrasting dark wings compared to the rest of their plumage even in younger plumages, and get a pale eye

I believe it was determined that all the birds reintroduced in Missouri were banded, and this one isn't. But I suppose it could be an offspring to them if those birds successfully bred and the young weren't banded. David El dom., 24 de octubre de 2021 10:03 a. m., Dave Cameron escribió: >

Hi all, Edward Landi and I have been looking at a 2nd cycle Glaucous-winged Gull here at Pueblo Reservoir's South Shore Marina. It's been flying around aggressively chasing other gulls and occasionally landing briefly. Look for a massive gull with pale uncontrasting wingtips and a smudgy black

Hi all, I was asked to post here that the bird thus far being reported as a Common Tern at Horseshoe Lake in Larimer County is in fact a (hatch-year) Arctic Tern. I am not the first to ID it as such, and I believe (correct if wrong) Josh Bruening is the original finder. Here is a list with pics.

Hey Colorado Birders, It's worth noting that there are currently two KING EIDERS at Lake Hattie near Laramie, Wyoming, a first state record found by Jonathan Lautenbach. This is only about 20 miles from Colorado as the crow (or eider) flies, and would be a new species for Colorado's list as well.
