WebIn general, birds are insensitive to the regulation of P(Glu) by insulin. However, there appears to be no phylogenetic or dietary pattern in the avian response to exogenous insulin. Moreover, the high levels of P(Glu) do not appear to lead to significant oxidative stress as birds are longer-lived compared to mammals.

WebThe correlation of basal rate of metabolism with various factors is examined in birds. Chief among these is body mass. As in mammals, much of the remaining variation in basal rate among birds is associated with food habits. Birds other than passerines that feed on grass, nectar, flying insects, or vertebrates generally have basal rates that are similar to … WebDec 3, 2024 · Bird metabolism is fairly high so they use energy at higher rates than mammals. Larger birds lose less body heat because of their size, and so use less energy (per unit of body weight) than small birds.
