Habitat

NatureServe records woodland, shrubland and chaparral, suburban and orchard areas, urban areas, and riparian (streamside) habitat[12]. The bird also uses gardens and meadows, in lowlands and, in some seasons, in the mountains[13]. Nests are placed in trees, vines, shrubs or man-made spots, at many heights up to about 9 meters[13].

Habitat types recorded by NatureServe[12]

Size, diet and lifespan

Anna's Hummingbird is about 10 cm (4 in) long[14] and weighs about 4 g[15]. Its diet is estimated at 90% nectar and 10% invertebrates[16]. It also takes tree sap and catches small insects and spiders[17]. A clutch is 2[18], and the female incubates them for 14 to 19 days[18]. Young leave the nest in 18 to 26 days[18].[19] The longest recorded lifespan in the wild is 8.5 years. The oldest known banded bird was at least 9 years 5 months old[4].

When to look for it

Anna's Hummingbird is active during the day[25]. NatureServe calls it a non-migrant or local migrant, and this can differ by population[24]. Some birds move up into the mountains after breeding, while others move north, south or east[26]. Observation records on GBIF are highest in January, March and April[27]. These records show when people look and report, not how many birds there are[27].

Status, range and habitat come from NatureServe Explorer (CC BY 4.0) and USFWS ECOS at the snapshot date. Listings change by federal rule. State lists are where NatureServe records the species, not a promise that you will see it there. Never name a place smaller than a state. GBIF and park records count observations and checklists. They show where and when people report the species, not how many animals live there.
