Abstract Studies of the relationship between heart rate (f(H)) and rate of oxygen consumption ((V) over dot(O2)), which are then used to predict field metabolic rate, frequently fail to incorporate body mass as a predictive variable. This is a potentially important omission in the study of animals whose body mass fluctuates substantially during their annual cycle. In an attempt further to improve estimates of field metabolic rate from f(H), we re-evaluated data on M-b, f(H) and (V) over dot(O2) from previous studies of macaroni penguins (Eudpytes chrysolophus) and king penguins (Aptenodytes patagonicus) and derived a new relationship to integrate these three quantities. This relationship is at least as accurate and precise as previously deter-mined relationships. We applied this same principle to published data on 11 of the 20 recognised penguin taxa to derive a relationship to predict,, from f(H) and M-b in penguins of any species. This result has interesting implications in terms of reducing the logistical burden in studies of field metabolic rate. (C) 2005 Elsevier Inc. All rights reserved.
