WebCompared with temperate birds, tropical birds have low reproduc-tive rates, slow development as nestlings, and long lifespans. These ‘‘slow’’ life history traits are thought to be associated with reduced energy expenditure, or a slow ‘‘pace of life.’’ To test predictions from this hypothesis, we measured exercise-induced 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
