Humming serves communication purposes by alerting other birds of the arrival of a fellow forager or potential mate. [72] The humming sound derives from aerodynamic forces generated by the downstrokes and upstrokes of the rapid wingbeats, causing oscillations and harmonics that evoke an acoustic quality likened to that of a musical instrument.
The red-billed streamertail (Trochilus polytmus), also known as the doctor bird, scissor-tail or scissors tail hummingbird, is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Jamaica and is the national bird of the country. [4] [5] [6]
xeno-canto is a citizen science project and repository in which volunteers record, upload and annotate recordings of bird calls and sounds of orthoptera and bats. [2] Since it began in 2005, it has collected over 575,000 sound recordings from more than 10,000 species worldwide, and has become one of the biggest collections of bird sounds in the world. [1]
The broad-tailed hummingbird, Selasphorus platycercus, is a member of the order Apodiformes, in the family Trochilidae. Hummingbird taxonomy has not been extensively studied, but its phylogenic division can be divided as a family into nine clades in which the broad-tailed hummingbird is a member of the "Bee group" and included in the Selasphorus genus.

Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards. Unless otherwise noted, all species listed below are considered to occur regularly in North America as permanent residents, summer or winter residents or visitors, or migrants.
This species uses diving displays (40–60 ft (12–18 m) dives) for territory defense and during courtship, producing an audible sound (a trill) as air passes through their feathers during the plunge. [16] In courtship, males perform "pendulum" display, flying back and forth in wide U-shaped arcs, making whirring sounds on each dive.
Male calliope hummingbird with its purple gorget (neck) feathers slightly extended. The calliope is the smallest breeding bird found in Canada and the United States. [3] [4] An adult calliope hummingbird can measure 7–10 cm (2.8–3.9 in) in length, span 11 cm (4.3 in) across the wings and weigh 2 to 3 g (0.071 to 0.106 oz).
