One parent, often the male, incubates the egg during the day, then the duties are shared during the night.

The chick hatches about ...

[ 13 ] The bird displays opportunistic feeding tendencies, although it may be able to fine-tune its meal choice in the moments before capture.
It may be mobbed by birds while there is still light, and by bats, other nightjar species or Eurasian woodcocks during the night.

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.
