The chicks of birds in many families, such as the waterfowl, waders, and gamebirds, are usually nidifugous. The opposite of nidifugous organisms are nidicolous ( / n aɪ ˈ d ɪ k ə l ə s / ny- DIK -ə-ləs ; from Latin nidus "nest" and -colus "inhabiting") organisms; a nidicolous organism is one which stays at its birthplace for a long time ...
Birds are vulnerable after they have left the nest, but before they can fly, though once fledged their chances of survival increase dramatically. [5] A pigeon fledgling on a tiled floor. One species, the ancient murrelet, fledges two days after hatching, running from its burrow to the ocean and its calling parents. Once it reaches the ocean ...
Very precocial birds can be ready to leave the nest in a short period of time following hatching (e.g. 24 hours). Many precocial chicks are not independent in thermoregulation (the ability to regulate their body temperatures), and they depend on the attending parent(s) to brood them with body heat for a short time. Precocial birds find their ...

Five butterfly species in the United States have gone extinct since 1950, and dozens more are on the verge of extinction according to the Xerces Society for Invertebrate Conservation.
Some species begin incubation with the first egg, causing the young to hatch at different times; others begin after laying the second egg, so that the third chick will be smaller and more vulnerable to food shortages. Some start to incubate after the last egg of the clutch, causing the young to hatch simultaneously. [10] Incubation periods for ...
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.

The female incubates the eggs for 11–14 days before they hatch. Then the female feeds the offspring while the male teaches them to fly and leave the nest, usually within 18 days of birth. The male also feeds the offspring a little less than half the time, easing the burden on the female.
