Range
Middle America : Northwest Mexico to Honduras
Habitat
Mountain forest, canyons. Arizona occurrences have been mostly at 5,000-
7,000′ in mountains, in open pine-oak forest or among sycamores in shady canyons. In Mexico, occurs widely in foothills and lower slopes of mountains, especially in oak woodland.

Reproduction
Breeding behavior is not well known.
Nest: Site is in deciduous tree or shrub, sometimes coniferous tree. Two Arizona nests were both in sycamores, 17-25′ above the ground, on horizontal branch or in near-vertical fork of branch. Nes
t (probably built by female alone) is a cup of thin dry grass, other plant fibers, spider webs, the outside covered with green lichens, sometimes with bits of grass trailing below.
Eggs: 2. White. Incubation is apparently by female only. Incubation period not well known, probably more than 2 weeks.
Young: Apparently cared for by the female only. Female feeds young by inserting bill deep into open mouth of young, then regurgitating food, probably including small insects and nectar. Age of young at first flight about 18
-20 days.

Feeding habits
Mostly nectar and small insects.
Feeds on nectar from a wide variety of flowers, including penstemon, thistle, many others. Will feed on sugar-water mixtures. Eats many small insects and spiders.
Behavior: Takes nectar from flowers whi
le hovering on rapidly beating wings; will also feed while perching if a convenient perch is available. Takes tiny insects caught in midair or from foliage, flying out from a perch to capture them or hovering in understory of forest. Will come to hummingb
ird feeders.

Conservation
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Migration
Mexico to Honduras. Sparse visitor and rare breeder in mountains of southeastern Arizona. Migration:
Probably not migratory over most of its range; strays north into United States during summer. In parts of Mexico, may move to lower elevations for the winter.
