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. Kavanau said extant birds (David J. Varricchio) [5] evolved and
Allofeeding evolved for different reasons in different species of birds. While sagebrush Brewer's sparrows allofeed to reduce predation during incubation, Sichuan jays allofeed to increase a female's nutritional level prior to egg laying, and chinstrap penguins allofeed to strengthen the bond between the pair during chick guarding.

The black mountain salamander mother broods her eggs, guarding them from predation as the larvae feed on the yolks of their eggs. They eventually break their way out of the egg capsules and disperse. [23] Some species of Gymnophiona (caecilians, with long, cylindrical, limbless bodies) brood their eggs. [24] A brooding female python.
The egg is not retained in the body for most of the period of development of the embryo within the egg, which is the main distinction between oviparity and ovoviviparity. [1] Oviparity occurs in all birds, most reptiles, some fishes, and most arthropods. Among mammals, monotremes (four species of echidna, and the platypus) are uniquely oviparous.
From a food safety perspective, cooking poultry, eggs, and beef to the appropriate internal temperature of 165˚F kills bacteria and viruses, including bird flu, according to the CDC. It’s also ...
All Papuan bowerbirds lay one egg, while Australian species lay one to three with laying intervals of two days. [ 6 ] [ 7 ] Bowerbird eggs are around twice the weight of those of most passerines of similar size [ 8 ] [ 9 ] – for instance eggs of the satin bowerbird weigh around 19 g (0.67 oz) as against a calculated 10 g (0.35 oz) for a ...
