Allofeeding is a type of food sharing behaviour observed in cooperatively breeding species of birds. Allofeeding refers to a parent, sibling or unrelated adult bird feeding altricial hatchlings, which are dependent on parental care for their survival. [1] Allofeeding also refers to food sharing between adults of the same species. [2]
Parental care is any behaviour that contributes to offspring survival, such as building a nest, provisioning offspring with food, or defending offspring from predators. Reptiles may produce self-sufficient young needing no parental care, while some hatchling birds may be helpless at birth, relying on their parents for survival.
The behavior of an amphibian hatchling, commonly referred to as a tadpole, is controlled by a few thousand neurons. [4] 99% of a Xenopus hatchling's first day after hatching is spent hanging from a thread of mucus secreted from near its mouth will eventually form; if it becomes detached from this thread, it will swim back and become reattached, usually within ten seconds. [4]
It can be an energetically demanding process, with adult albatrosses losing as much as 83 g of body weight a day. [6] Megapode eggs take from 49 to 90 days depending on the mound and ambient temperature. Even in other birds, ambient temperatures can lead to variation in incubation period. [7] Normally the egg is incubated outside the body.
Often parents change the level of parental care provided to manage the cost and benefits of parental care. Passerine species in North America have a large brood size containing 4–6 offspring and a 50% adult survival rate, and those in South America have a smaller brood size containing 2–3 offspring and a 75% adult survival rate.
The birds hop along tree branches searching for food, sometimes hanging upside down or hovering; they may make short flights to catch insects in the air. Seeds and berries become more important in winter, though insect eggs and pupae are eaten when available. [14] Black-capped chickadees have also been known to eat the fat off of dead mammals. [30]
Scientists can use fecal sacs to learn a number of things about individual birds. Examination of the contents of the sac can reveal details of the nestling's diet, [14] [15] and can indicate what contaminants the young bird has been exposed to. [16] The presence of an adult bird carrying a fecal sac is used in bird censuses as an indication of ...
The smallest species by body mass appears to be the green-backed honeyguide, at an average of 10.2 g (0.36 oz), and by length appears to be the Cassin's honeyguide, at an average of 10 cm (3.9 in), while the largest species by weight is the lyre-tailed honeyguide, at 54.2 g (1.91 oz), and by length, is the greater honeyguide, at 19.5 cm (7.7 in).
