In the Southwest, most common in canyons and along rivers. In arid areas, most often found near cottonwood, sycamore, willow, salt-cedar, sugarberry, and oak. Birds wintering along Gulf very often spend time in shade of oaks.Back to top

Most Black-chinned Hummingbird nests have been found an average of 6 feet and at most 12 feet above the ground, but this may be because nests at this height are easier for observers to find. The nest is often on an exposed small horizontal dead branch well below the canopy.
When newly built, the nest is a compact, deep cup constructed of plant down, spider silk and cocoon fibers. As the nestlings grow, the nest stretches into a wider, shallower cup. Nests from cooler areas are thicker-walled than nests from warmer areas.

After feeding may perch on high, bare branch for several minutes, surveying territory. Captures small insects in flight (or, in the case of spiders, while ballooning) or on flowers and even on the ground. May fly from perch to grab a single flying insect and then return to perch. May capture many insects in rapid succession in a swarm. Extracts nectar from flowers by extending tongue into the corolla while hovering. During courtship and territorial defense, males display by diving 66-100 feet.Back to top
Black-chinned Hummingbirds populations increased by approximately 0.3% per year between 1966 and 2019, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 8.8 million and rates them 9 out of 20 on the Continental Concern Score, indicating a species of low conservation concern. In some places, populations are increasing owing to the popularity of hummingbird gardens and hummingbird feeders. In much of the arid western U.S., Black-chinned Hummingbirds depend on intact streamside habitats, so these areas are important to preserve.Back to top
