WebFeb 13, 2016 · Among birds, many studies have shown that tropical species have a slower pace of life than temperate-breeding species. The pace of life has been hypothesized to affect metabolism and, as predicted, tropical birds have lower basal metabolic rates (BMR) than temperate-breeding birds. WebTropical birds typically exhibit a 'slow pace of life' relative to higher latitude species. This is often manifested as slow development, low fecundity, and high survival.

WebBirds are a group of warm-blooded vertebrates constituting the class Aves (/ ˈ eɪ v iː z /), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 … Webechnie 2008). Accordingly, if life history predicts the ener-getic ‘pace of life’, then tropical birds should have lower metabolic rates than temperate birds. Early work on tropical bird energetics was ambivalent, with low metabolic rates reported in some species (Weath-ers 1979; Hails 1983; Tieleman et al. 2006) but not others
