Anna’s Hummingbird Nest Cam 2013

Videos recorded live in May 2013 from the Anna’s Hummingbird Nest Cam 2013 through Ustream.tv. This female selected a high traffic, urban location for her nest, though the nest is well hidden in the dappled shade. See below for information on Anna’s Hummingbirds, the nest, and the previous nest cam. For a series of posts on what happened at this nest – mother did not return, emergency intervention for chicks, delivery of chicks to wildlife rescue, see our Facebook Page: Arizona Hummingbird Nest Cam.

This nest was in a large juniper tree just off a lawn. The nest was 8-9 feet off the ground, about 10 feet from an alley used daily by pedestrians, dogs, and cats, and the tree is beside an active carport. There is a bus stop within 50 feet of the tree, a frequently used sidewalk within 35 feet, and the lanes of traffic are about 40 feet away. The juniper is used as a frequent stop for other birds, including nest raiders, as they move from open areas to the more sheltered yards nearby. Despite these factors, the nest was very well hidden, as was the camera.

Previous Anna’s Hummingbird Nest cam stream – April 2013

We were able to live stream from another Anna’s Hummingbird nest, with a different female, in April 2013. This other nest location had more cover and previous successes, but the April 2013 chicks did not survive. See below for background. The video below is from that nest: Mother feeding chick on its first day, April 2, 2013.

What happened?

In 2012 , this previous female Anna’s Hummingbird was able to raise 2 sets of 2 chicks successfully. When this Anna’s Hummingbird returned in March 2013 to re-use her nest, Curve-billed Thrashers had already established their own new nest in the same Texas Ebony tree, about 10 feet above the hummingbird nest. The Thrashers passed the hummingbird nest each day on the way up to their nest. The Anna’s Hummingbird refurbished her own nest and laid two eggs in March 2013. The hummingbird chicks hatched on April 2 and 3, 2013.

Curve-billed Thrashers eat insects and seeds, according to bird guides and Wikipedia. Unfortunately, the official sources on Thrashers are incomplete. The nest was raided by the Thrashers on April 11, 2013, when the hummingbird chicks were 5 and 6 days old. The chicks were stolen. The female hummingbird abandoned the nest. This was caught on video. Within a couple of days, two Thrasher chicks fledged from the Thrasher nest.

We have since seen the first female Anna’s Hummingbird. Within a day of losing her chicks, she was in the backyard, collecting spiderwebs and flying off. She continues to return to the backyard to feed. We recognize her by a white marking on her left side. We not think that she is the female that has nested in the Juniper tree, in part due to the birds’ markings and in part due to the fact that she seems to fly off elsewhere.

You can sometimes see a female hummingbird collect spider webs, then return to the nest to wipe them from her bill across the sides of the nest. The nest stretches as the chicks grow. See this post for nest pictures of another nest before and after chicks.

Incubation

14-19 days**.

Feeding

The mother feeds the chicks a mixture of insects and nectar that she collects and regurgitates. Hummingbirds eat small insects for protein and nectar from flowers or hummingbird feeders for energy. See Attract Hummingbirds for information on hummingbird plants, feeders, and other things hummingbirds like.

Leaving the nest

18-23 days** until the chicks fledge (leave the nest).

Where is this nest?

This nest is in Tempe, Arizona in a large juniper tree beside a lawn. The nest is 8-9 feet above the ground, about 40 feet from the edge of a busy city street, 35 feet away from a frequently used sidewalk, 10 feet from an alley used by pedestrians, dogs, and cats, and several feet away from an active car port. This particular nest was discovered in April 2013.
