[cobirds] Black-billed Cuckoo, July 16, 2021, Elbert County
A Black-billed Cuckoo was reported yesterday by Cecile Lee near the cemetery on the north edge of the town of Elbert – oddly enough in Elbert county. Jeanne and I headed that way with low expectations, but high hopes. It was eleven years ago that we had traveled to Weld county’s Norma’s Grove in search of this species. We did not find the bird, but did have our first opportunity to meet Ira Sanders. Today we found the bird in the trees on the east side of North Elbert Highway across from the intersection with CR-102. We parked in a large pull-off area and walked to the fence on the east edge of the property - about 100 yards in from the road. It took some time before we heard the bird call and then we located it in the trees at mid-level. Fairly large bird with black bill, long tail, dark back and white stomach. We could not ID an eye ring. Tail spots seemed smaller than the YBCU we are used to seeing in Colorado. Call seemed to match recording on Sibley app. Because of all the rain, the grass and weeds are quite high in this location, so long pants are recommended. Of course, I was wearing shorts! Good birding, all. Mel Goff Colorado Springs -- -- You received this message because you are subscribed to the Google Groups "Colorado Birds" group.

Re: [cobirds] odd incident
Interesting observation Dave. To add to that I had a pair of Bullock's Orioles nest successfully in a blue spruce tree in my yard a few years back, so they are indeed adaptable.

[cobirds] odd incident
On July 13 a friend of mine and I hiked up Young's Gulch in Poudre Canyon.

[cobirds] Coopers Hawk Nesting Now in Jefferson Co?
I have a Coopers Hawk who is just starting to build a nest in my backyard. Isn't this kind of late for him to be starting this? Is there any chance for him to attract a mate and for them to be successful this late? I'm also asking because I'm having some limb trimming done on a tree that is right next to one he's building in in the next couple of weeks. It's not major work, but they will be using a chain saw. It won't take them long to do, and I can make sure the crew avoid hitting the tree with the nest. If he does attract a mate, will they return when the work is done without too much stress?
