  2. Endotherm - Wikipedia

    en.wikipedia.org/wiki/Endotherm

    Penguin feathers are scale-like and serve both for insulation and streamlining. Endotherms that live in very cold circumstances or conditions predisposing to heat loss, such as polar waters, tend to have specialised structures of blood vessels in their extremities that act as heat exchangers. The veins are adjacent to the arteries full of warm ...

  3. Ectotherm - Wikipedia

    en.wikipedia.org/wiki/Ectotherm

    In cool weather the foraging activity of such species is therefore restricted to the day time in most vertebrate ectotherms, and in cold climates most cannot survive at all. In lizards, for instance, most nocturnal species are geckos specialising in "sit and wait" foraging strategies. Such strategies do not require as much energy as active ...

  4. Thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Thermoregulation

    Mammalian skin is much thicker than that of birds and often has a continuous layer of insulating fat beneath the dermis. In marine mammals, such as whales, or animals that live in very cold regions, such as the polar bears, this is called blubber. Dense coats found in desert endotherms also aid in preventing heat gain such as in the case of the ...

    To help the birds survive the cold, Winger said people can offer seeds in bird feeders or thistle feeders. "Backyard bird feeders are good. I think for a lot of our resident birds like chickadees ...

  6. Chionophile - Wikipedia

    en.wikipedia.org/wiki/Chionophile

    Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so.. Chionophiles are any organisms (animals, plants, fungi, etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning "snow", and -phile meaning "lover").

  7. Warm-blooded - Wikipedia

    en.wikipedia.org/wiki/Warm-blooded

    Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes

  8. Homeothermy - Wikipedia

    en.wikipedia.org/wiki/Homeothermy

    Cold-blooded animals are often limited by external temperatures, which can affect their ability to hunt, escape predators, and carry out other essential activities. Homeothermy could have provided a selective advantage by allowing animals to be active for longer periods of time, increasing their chances of survival.

    Many bird leave for the winter, migrating south to warmer climes. Those that stay avoid the hazards of migration and maintain a year-round territory.
