Hummingbird Update

The Anna's hummingbird nest across the street remains active.

Yesterday, I saw two medium-sized nestling bills.

The nestlings are 13 to 18 days old and will be in the nest for another five to ten days.
The nestling period of hummingbirds is much longer than other small, open-nesting birds. Females care for young without help from males, so nestling growth rate is probably limited by the amount of food a tiny single parent can deliver.

The little nestlings here have already been hardened by cold and wet weather, so they should have no trouble making it out of the nest.

I saw my first Rufous today! Last year I saw juv. Anna's and could only ID them due to their smaller bills. Fun to see!
