hummingbird
Synonym discussion
Sense: noun/1
Hummingbird is the standard English name for any bird of the family Trochilidae, known for its small size, iridescent feathers, and ability to hover. The informal shortening hummer appears in casual US speech and birdwatching blogs but is too informal for academic writing. The swift is a different bird family (Apodidae) — swifts are larger, fly faster, cannot hover, and lack the long thin beak that hummingbirds use to reach nectar. A quick way to tell them apart: if the bird is hovering in front of a flower, it is a hummingbird; if it is racing through the sky in a curved path, it is probably a swift.
Etymology
The name 'hummingbird' was first recorded in English in the 1600s. It combines 'humming' (referring to the buzzing sound of the bird's fast-beating wings) with 'bird'. Early European explorers in the Americas noticed the sound before they could see the tiny bird clearly. The scientific family name Trochilidae comes from the Greek word 'trokhilos', a name the ancient Greeks used for a small unidentified bird.
