The Baby New Year is a personification of the start of the New Year commonly seen in editorial cartoons.

Extremely precocial species are called "superprecocial". Examples are the megapode birds, which have full-flight feathers at hatching and which, in some species, can fly on the same day. [ 3 ] Enantiornithes [ 4 ] and pterosaurs [ citation needed ] were also capable of flight soon after hatching.
A pair of welcome swallow chicks, Hirundo neoxena, taken the day after they fledged. All birds are considered to have fledged when the feathers and wing muscles are sufficiently developed for flight. A young bird that has recently fledged but is still dependent upon parental care and feeding is called a fledgling.

A possible evolutionary timeline by Kavanau suggests that basal theropod dinosaurs evolved into birds that evolved unique bi-parental care, after which avian birds evolved homeothermy and flight. Burley and Johnson (2002), Tullberg et al. (2002), Prum (2002), and Varricchio et al. (1999) questioned the male evolutionary shift from no care to ...
The other significant advantage is the chance for the healthiest young animals to be favored from a group. Rather than it being a conscious decision on the part of the parents, the fittest and strongest baby competes most successfully for food and space, leaving the weakest young, or runts, to die through lack of care.
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.
