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.
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
In terms of their reproductive biology and socio-sexual behavior, accipitrids share many characteristics with other extant groups of birds that appear not be directly related, but all of which have evolved to become active predators of other warm-blooded creatures.
Warm-blooded creatures — including birds, who are descended from dinosaurs, and humans — keep their body temperature constant whether the world around them runs cold or hot.
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.
In western North America during the twilight of the dinosaur age, the unquestioned ruler was Tyrannosaurus rex, one of the largest terrestrial predators in Earth's history. Researchers have ...
Prey is typically struck and captured in mid-air; the peregrine falcon strikes its prey with a clenched foot, stunning or killing it with the impact, then turns to catch it in mid-air. [81] If its prey is too heavy to carry, a peregrine will drop it to the ground and eat it there.
Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
