If predators were cold-blooded while their prey were warm-blooded, the predators might have struggled to hunt efficiently in cooler conditions. Homeothermy in prey species could have provided a competitive advantage by allowing them to maintain consistent performance across a wider range of temperatures.
Warm-blooded is a 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.
Birds are a group of warm-blooded vertebrates constituting the class Aves ... (meaning "true birds", ... Birds of prey are highly represented, though some nations ...
Some birds, like the ruby-crowned kinglet, use a combination of these tactics. "Crevice-gleaning" is a niche particular to dry and rocky habitats.

Bird meanings and symbolism are open to wide interpretation and can vary across cultures and traditions. Popularly, owls are associated with wisdom, and doves are widely associated with peace.
Birds, especially waders, often have very well-developed heat exchange mechanisms in their legs—those in the legs of emperor penguins are part of the adaptations that enable them to spend months on Antarctic winter ice. [9] [10] In response to cold, many warm-blooded animals also reduce blood flow to the skin by vasoconstriction to reduce ...
Warm-blooded prey includes mice and the eggs and chicks of other beach-breeding birds; least terns, little terns and members of its own species may be victims. [57] [58] [59] The greater crested tern will also occasionally catch unusual vertebrate species such as agamid lizards and green sea turtle hatchlings, and follows trawlers for discards ...
As Wilson notes, smaller birds will attack and annoy red-tails, representing outside forces trying to hamper our ability to take flight. But the red-tail's signature crimson tail feathers help ...
