Dusky woodswallow (Artamus cyanopterus) parent feeding a wasp to chicks. 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]
Bi-parental care is the most common form in birds, especially in passerines. A mating pair equally contributes to feeding and guarding the offspring. It occurs in approximately 85% of bird species. [11] The hatchling benefits from the mutual care at the cost of the parents' future reproductive success.
The span between precocial and altricial species is particularly broad in the biology of birds. Precocial birds hatch with their eyes open and are covered with downy feathers that are soon replaced by adult-type feathers. [17] Birds of this kind can also swim and run much sooner after hatching than altricial young, such as songbirds. [17]

With a recorded history dating to the 6th century, [ 1 ] the feeding of wild birds has been encouraged and celebrated in the United States and United Kingdom, with it being the United States' second most popular hobby having National Bird-Feeding Month ...

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.

Children can identify different species of birds with a field guide and can learn about the birds' feeding and living habits. These observations can then provide excellent research opportunities for school projects and reports. Feeding wild birds in the backyard is an easy hobby to start and need not overtax the family budget.
