During cold temperatures, Anna's hummingbirds gradually gain weight during the day as they convert sugar to fat. Territorial vocal signals may be produced in rapid succession to discourage aggressive encounters, with the chirping rate and loudness increasing when intruders persist. The bee hummingbird ( Mellisuga helenae) – the world's smallest bird – evolved to dwarfism likely because it had to compete with long-billed hummingbirds having an advantage for nectar foraging from specialized flowers, consequently leading the bee hummingbird to more successfully compete for flower foraging against insects. Hummingbirds also possess the most sophisticated hovering flight of all birds, a necessity for rapidly visiting many flowers without perching. Dozens of hummingbird species live year-round in tropical mountain habitats at high altitudes, such as in the Andes over ranges of 1,500 metres (4,900ft) to 5,200 metres (17,100ft) where the partial pressure of oxygen in the air is reduced, a condition of hypoxic challenge for the high metabolic demands of hummingbirds.

During a day of nectar consumption with a corresponding high water intake that may total five times the body weight per day, hummingbird kidneys process water via glomerular filtration rates (GFR) in amounts proportional to water consumption, thereby avoiding overhydration.

While most hummingbirds do not migrate, the rufous hummingbird has one of the longest migrations among birds, traveling twice per year between Alaska and Mexico, a distance of about 3,900 miles (6,300km). Gastrointestinal and renal responses to water intake in the green-backed firecrown (Sephanoides sephanoides), a South American hummingbird". They may be set in motion by twirling a handle with the fingers, by pulling a rope coiled around the body, or by means of a built-in auger (spiral plunger). During courtship, some male species dive from 30 metres (100ft) of height above a female at speeds around 23m/s (83km/h; 51mph). Here, Sonic's Humming Top look like it did in Sonic Advance 2, except its winds are white instead of blue.

Functional art tops have become collectibles built using varied techniques in metal-working, glass-working, and wood-working.

Anna's hummingbird is the official city bird of Vancouver, British Columbia, Canada, [122] and is a non-migrating resident of Seattle where it lives year-round through winter enduring extended periods of subfreezing temperatures, snow, and high winds.
