The high metabolic rate of hummingbirds – especially during rapid forward flight and hovering – produces increased body heat that requires specialized mechanisms of thermoregulation for heat dissipation, which becomes an even greater challenge in hot, humid climates. [104] Hummingbirds dissipate heat partially by evaporation through exhaled air, and from body structures with thin or no feather covering, such as around the eyes, shoulders, under the wings ( patagia), and feet. [105] [106]a b Crabtree, H. (1909). An Elementary Treatment of the Theory of Spinning Tops and Gyroscopic Motion. London: Longman, Green and C. ISBN 9781418179892. The heart rate of hummingbirds can reach as high as 1,260 beats per minute, a rate measured in a blue-throated hummingbird with a breathing rate of 250 breaths per minute at rest. [6] [103] Heat dissipation [ edit ] Many hummingbird species use spider silk and lichen to bind the nest material together and secure the structure. [140] [141] The unique properties of the silk allow the nest to expand as the young hummingbirds grow. Two white eggs are laid, [23] [140] which despite being the smallest of all bird eggs, are large relative to the adult hummingbird's size. [140] Incubation lasts 14 to 23 days, depending on the species, ambient temperature, and female attentiveness to the nest. [23] [139] The mother feeds her nestlings on small arthropods and nectar by inserting her bill into the open mouth of a nestling, and then regurgitating the food into its crop. [139] Hummingbirds stay in the nest for 18–22 days, after which they leave the nest to forage on their own, although the mother bird may continue feeding them for another 25 days.

As calculated by displacement of body size, the rufous hummingbird makes perhaps the longest migratory journey of any bird in the world. At just over 3 inches (7.6cm) long, rufous hummingbirds travel 3,900 miles (6,300km) one-way from Alaska to Mexico in late summer, a distance equal to 78,470,000 body lengths, then make the return journey in the following spring. [167] [171] By comparison, the 13 inches (33cm)-long Arctic tern makes a one-way flight of about 11,185 miles (18,001km), or 51,430,000 body lengths, just 65% of the body displacement during migration by rufous hummingbirds.
