Why do hummingbirds make a sound?
A hummingbird is named for the prominent humming sound its wingbeats make while flying and hovering to feed or interact with other hummingbirds. Humming serves communication purposes by alerting other birds of the arrival of a fellow forager or potential mate. The humming sound derives from aerodynamic forces generated by both 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 humming sound of hummingbirds is unique among flying animals, compared to the whine of mosquitoes, buzz of bees, and 'whoosh' of larger birds.
Why are hummingbirds bright?
To serve courtship and territorial competition, many male hummingbirds have plumage with bright, varied coloration resulting both from pigmentation in the feathers and from prismal cells within the top layers of feathers of the head, gorget, breast, back and wings. When sunlight hits these cells, it is split into wavelengths that reflect to the observer in varying degrees of intensity, with the feather structure acting as a diffraction grating. Iridescent hummingbird colors result from a combination of refraction and pigmentation, since the diffraction structures themselves are made of melanin, a pigment, and may also be colored by carotenoid pigmentation and more subdued black, brown or gray colors dependent on melanin.

How big are hummingbird eyes?
Although hummingbird eyes are small in diameter (5–6 mm), they are accommodated in the skull by reduced skull ossification, and occupy a relatively larger proportion of the skull compared to other birds and animals. Further, hummingbird eyes have relatively large corneas, which comprise about 50% of the total transverse eye diameter, combined with an extraordinary density of retinal ganglion cells responsible for visual processing, containing some 45,000 neurons per mm 2. The enlarged cornea relative to total eye diameter serves to increase the amount of light perception by the eye when the pupil is dilated maximally, enabling nocturnal flight.
