Behavior
Eggs
2. White. Incubation is by female only, probably 2 weeks or longer.
Young
Female feeds the young, sticking her bill deep into their mouths and regurgitating tiny insects, perhaps mixed with nectar. May raise two broods per year.
Feeding Behavior
At flowers, usually feeds while hovering, extending its bill and long tongue deep into the center of 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.
Diet
Mostly nectar and insects. Takes nectar from flowers, and will feed on tiny insects as well. Often visits red tubular flowers such as turk's-cap and red salvia. Will also feed on sugar-water mixtures in hummingbird feeders.
Nesting
Breeding behavior is not well known. In Texas, the nesting season extends at least from April to August. Nest site is usually in large shrub or small deciduous tree, such as hackberry or Texas ebony, usually only a few feet above the ground. Nest (built by female) is a cup of plant fibers, stems, shreds of bark, spider webs, lined with plant down. The outside is camouflaged with bits of lichen, flower petals.
Climate Vulnerability
Conservation Status
Numbers probably declined in the past with loss of habitat, but current population seems to be stable.
