Nesting Habits of the Allen's Hummingbird
Despite their tiny size, male Allen's Hummingbirds are very aggressive and territorial. If a random male should stray into its domain, the male Allen’s hummingbird will chase it out. They have been known to attack and chase off other hummingbird species as well as much larger predators.
The male Allen's Hummingbird attracts a female using a complex aerial show which includes vocalizations. This flight of courtship is a frantic back and forth ascending and descending arc, like the swaying of a pendulum, covering around 25 feet. In this flight of love, the male Allen's hummingbird makes vocalizations with shuttling, followed by a j-shaped, speed dive of about 100’.
Allen’s hummingbirds make their nest from down, weed stems and plant fibers and coat it with lichens to provide structure. Females lay two white eggs that will be incubated for up to 17 days.
Although the young Allen's Hummingbirds leave the nest three weeks after hatching, the mother will feed the young for several more weeks. After that, the baby Allen’s hummingbirds are on their own!
