Re: [cobirds] Two late nestings at Littleton, Arapahoe Co

Yesterday, I watched a Red-tailed Hawk remove a dead branch from a neighborhood cottonwood (Centennial in Arapahoe Co). Taking off, the bird deftly switched the stick from its beak to its talons, mid-flight. Quite impressive, but I was left wondering if this isn't rather early (or really, really late) for nest building activities for a Red-tailed? The Birds of the World database doesn't suggest this should be happening now. Perhaps some very early rehearsal?

Setting up for banding at Barr Lake this morning.  Greeted at the parking lot by a just fledged family of Western Wood-Pewee.  Two young, still not fully feathered but fledged balls of wild looking feathers were yelling constantly for their parents' attention.    I couldn't tell if they were yelling for food or just the chaos and excitement of first flights.

To add to David's post, although decidedly less interesting, there's an active House finch nest next to my house with noisy nestlings. There was a Barn Swallow nest with 2 young 1-2 days from fledging at Clement Park on Friday. I haven't gone back to check to see if they fledged. They seemed to be pretty late nests. These birds are all in Littleton, Jefferson County.

On 7/27 I found a female Broad-tailed Hummingbird at a new nest in a spruce at Littleton Cemetery, the first hummer nest I've found there. Since then she has been sitting on the nest, apparently on eggs (can't see in), and she was sitting yet today. This suggests maybe at least 18-19 days of incubation which is at the outside end of the norm, and the nest is late for a nest with eggs for this species.

Two fresh juvie Cooper's Hawks appeared begging at St Mary Church along S. Prince St. this morning. They weren't around earlier and seemed pretty new. I see most Cooper's families fledging by early to mid-July. I hadn't had any other families in the greater neighborhood area there this year.
