In early spring, a narrow strip of scrub and chaparral along the Pacific Coast starts buzzing with the sights and sounds of the coppery and green Allen's Hummingbird. Males flash their brilliant reddish orange throat and put on an elaborate show for the females, swinging in pendulous arcs before climbing high into the sky and diving back down with a sharp squeal made by their tails. These early migrants mostly spend the winter in Mexico, but some stay in southern California year-round.
