Two late nestings at Littleton, Arapahoe Co

[David Suddjian]

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.

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.

I too came across a Broad-tailed Hummingbird female sitting on a nest just 2 days ago in Boulder County, at around 7200 ft. I assume there were eggs present, but couldn't check since the nest was up a tall power pole. I also assume the verdant terrain surrounding the site is what's encouraging these late breeding (2nd brood?) attempts.

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.

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?

To follow up on the tardy Broad-tailed Hummer nest at Littleton Cemetery...  I was not able to view it again after 8/15 until today 8/18. The effort has failed. Today the nest was gone from its twig, as if a predator destroyed it, or maybe the wind blew it out. I could not find any remains of it.
