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

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.

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.
