Kavanau (1987) was the first to find that unique bi-parental care seen in modern birds probably evolved from extinct birds. They developed the ability to provide protection, escorting, nurturing and egg guarding abilities for their young. Evolution of homeothermy and flight most likely occurred in bi-parental birds with precocial chicks.
In birds, this parental care system is generally attributed to the ability of male birds to engage in most parental behaviours, with the exception of egg-laying. Due to their endothermy and small size at birth, there is a huge pressure for infant birds to grow up quickly to prevent energy loss.
In contrast to the large clutch sizes found in many bird species with biparental care, bats typically produce single offspring, which may be a limitation related to lack of male help. It has been suggested, though not without controversy, that paternal care is the ancestral form of parental care in birds. [9]

Allofeeding refers to a parent, sibling or unrelated adult bird feeding altricial hatchlings, which are dependent on parental care for their survival. [1]

[1] [2] Parental investment may be performed by both males and females (called biparental care), females alone (exclusive maternal care) or males alone (exclusive paternal care). Care can be provided at any stage of the offspring's life, from pre-natal (e.g. egg guarding and incubation in birds, and placental nourishment in mammals) to post ...
While taking care of pet birds and wild birds are different, they do share some overlap — such as investing in a good bird bath for your feathered friends to splash about in. A shallow bird bath ...
Experts say kids can benefit from a "bird nesting" situation where the kids stay in the house post-divorce, and the parents travel between two homes.
