They also eat small flying insects, which they catch by darting about within a swarm or by sallying out from a perch. Insects provide protein, vitamins, and minerals that are an essential part of the hummer’s diet. Throughout the hummingbird family, breeding systems follow just a few distinct patterns. Many North American species rely on spectacular stylized display flights that trace a “J,” a “U,” or an “O” in the air. Often their flights are oriented to permit the male to catch sunlight with his splendid iridescent throat feathers, or gorget, to impress a nearby female. Other species add song to the display. Hummer songs are not usually a lilting melody, but rather a few strident, scratchy notes given from a perch.
