One parent, often the male, incubates the egg during the day, then the duties are shared during the night. Changeovers to relieve incubating parents and feed chicks are infrequent to minimise attention to the nest, as potoos are entirely reliant on camouflage to protect themselves and their nesting site from predators. The chick hatches about ...
Hatching success is 90% and the fledging survival rate is 70–90%. Average mortality is 70–80% in the first year and 40–70% for the adult. Although the record age is more than 11 years, most survive less than four years. [7] Barn swallow nestlings have prominent red gapes, a feature shown to induce feeding by parent birds.
Bird feeding is the activity of feeding wild birds, often by means of bird feeders. 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 ...
Sunflower seeds are readily taken from bird feeders. The birds take a seed in their beak and commonly fly from the feeder to a tree, where they proceed to hammer the seed on a branch to open it. [31] Like many other species in the family Paridae, black-capped chickadees commonly cache food, mostly seeds, but sometimes insects, also. [32]

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.

Nankeen night heron hatchlings are altricial and fledge around six to seven weeks after birth. [10] The chicks are aggressive to all adults, including parents, that approach the nest. [9] They may leave the nest after around two weeks, and return to be fed. [10] They are fed away from the nest by the third week of hatching. [9]
