The Anna's Hummingbird is a common year-round, breeding resident on campus, mirroring its general status and distribution in southern California. They can be seen almost anywhere on campus, but especially near nectar sources (flowering trees, plants, etc.).

High Count: 25, Average Count: 4-8

The adult male Anna's Hummingbird can be identified by its bright pink gorget (iridescent feathers on its head). This pink color, however, comes from the reflection of sunlight, so it can appear dark from different angles. Female Anna's Hummingbirds are similar in size and shape to males, but lack the pink gorget. Females can be distinguished from female Costa's Hummingbird by relatively dingier (usually green or gray) underparts (throat, breast, and belly), and when perched the tail extends beyond the wingtips. Immature males look like females but often have iridescent pink feathers scattered about the throat and/or head.
