Behavior
Eggs
2. White. Incubation is by female only, probably more than 2 weeks.
Young
Female feeds the young, sticking her bill deep into their mouths and regurgitating tiny insects, perhaps mixed with nectar.
Feeding Behavior
At flowers, usually feeds while hovering, extending its bill and long tongue deep into the flower. At feeders, may either hover or perch. To catch small insects, may fly out and grab them in midair, or hover to pluck them from foliage; sometimes will take insects from spider webs.
Diet
Mostly nectar and insects. Takes nectar from flowers, and eats many tiny insects as well. Favors red or orange tubular flowers such as bouvardia or desert honeysuckle. Will also feed on sugar-water mixtures in hummingbird feeders.
Nesting
Male has soft jumbled song, not often heard; seems to defend territory mostly by perching high, watching for intruders and chasing them away. Nest site is in deciduous shrub or low tree, saddled on horizontal or drooping branch or placed in fork, usually 3-9 feet above the ground. Nest (built by female) is a relatively loose cup of grasses, plant fibers, spider webs, lined with plant down. The outside is camouflaged with bits of leaves or bark; unlike many hummingbird nests, outside usually not decorated with lichens.
Climate Vulnerability
Conservation Status
Very common in limited range in U.S. and in parts of Mexico.
