Knowra Hummingbird Hummingbird A small bird native to the Americas in the family Trochilidae, distinguished by hovering flight, rapid wingbeats, and frequent feeding on flower nectar.
Hummingbird flight : The flight behavior of hummingbirds, including hovering, backward flight, and rapid maneuvering. Figure-eight wing strokes generate lift on both the forward and backward strokes, enabling sustained hovering.
Trochilidae : The bird family comprising all hummingbirds, with more than 350 recognized species. Every hummingbird belongs to this New World family.
Hummingbird garden : A garden designed to provide hummingbirds with nectar-rich flowers, shelter, and suitable habitat. Native flowering plants can support hummingbirds without relying solely on feeders.
Ruby-throated hummingbird : A hummingbird that breeds across eastern North America and winters mainly in Central America. Its trans-Gulf migration is a well-known example of long-distance hummingbird travel.
Climate change and birds : The effects of long-term climatic shifts on birds, including their ranges, timing, and survival. Changing temperatures and flowering schedules may disrupt hummingbird food and migration timing.
Hummingbird metabolism : The processes that supply and regulate the exceptionally high energy demands of hummingbirds. Their intense flight requires rapid energy use, balanced by nightly torpor and frequent feeding.
Bird : A warm-blooded vertebrate in the class Aves, characterized by feathers, a beak, and egg-laying. Hummingbirds share the defining anatomy and evolutionary history of birds.
Hummingbird feeder : A device that supplies sugar water to attract and feed hummingbirds. Feeders offer supplemental food, but need regular cleaning to limit microbial growth.
Anna's hummingbird : A medium-sized hummingbird native to western North America, including coastal and urban habitats. Its year-round presence in parts of the West illustrates hummingbird adaptation to human-altered landscapes.
Habitat fragmentation : The division of continuous habitat into smaller, separated patches. Fragmented landscapes can limit access to flowers, nesting sites, and migration stopovers.
