When water temperature is raised due to thermal pollution, chum salmon tends to dive into deep water for thermoregulation. This reduces the time chum salmon spent in surface water column and reduce the chance for chum salmon to approach natal river since the chemical cue for natal homing is concentrated on surface water.
In many species, parents continue to care for their fledged young, either by leading them to food sources, or feeding them. 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

The majestic Emperor Penguin is most renowned for being the largest penguin species in the glacial habitat of Antarctica, widely recognized by the yellow patch on their neck. These endearing birds ...
They do not go far from the nest, return to it at night, and take some weeks to completely leave the nest. Many fledglings are found on the ground and in low shrubs during this period, where they continue to be cared for until they can make their way up into the trees. These birds are often mistakenly 'rescued'. The fledglings seek out siblings ...

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 ...
