Allen's Hummingbird Information This hummingbird was named after Charles Andrew Allen (1841-1930) who was a naturalist from Massachustts who moved to California. This hummingbird was originally named Selasphorus alleni to honor Charles Andrew Allen, but was later changed to Selasphorus sasin. The reason for this is that it had already been described and given this scientific name prior to Allen discovering it. It closely resembles the Rufous hummingbird, however, there are ways to tell them apart. More

The Allen's Hummingbird constructs its nest out of plant fibers, down, and weed stems, coating the nest with lichens to give it structure. The nest is placed above ground on a tree branch or the stalk or stem of a plant. The female lays two white eggs, which she will incubate for 15 to 17 days. The young will leave the nest about three weeks after hatching. The mother will continue to feed the fledglings for several more weeks, then the young are left to fend for themselves. More
