The hypothesized population ratios of predatory dinosaurs to their prey is a signature trait of warm-blooded predators rather than cold-blooded ones. Birds are warm-blooded and evolved from dinosaurs; therefore, a change to a warm-blooded metabolism must have taken place at some point.
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.
Some birds, like the ruby-crowned kinglet, use a combination of these tactics. "Crevice-gleaning" is a niche particular to dry and rocky habitats. Gleaning birds are typically small with compact bodies and have small, sharply pointed beaks. Birds often specialize in a particular niche, such as a particular stratum of forest or type of ...
Warm-blooded animals could have gained an advantage by creating an inhospitable environment for many disease-causing organisms, thus reducing the risk of infections. Insulation and Thermoregulation : Homeothermy could have originated as a response to the development of insulating structures like fur, feathers, or other coverings.
Birds of prey specialise in hunting mammals or other birds, while vultures are specialised scavengers. Birds are also preyed upon by a range of mammals including a few avivorous bats.
