“…6). This value is considerably higher than the figures reported for most other birds, except for goatsuckers and frogmouths (Bartholomew et al, 1962;Dawson W. R. & Fisher, 1969;Lasiewski, 1969;Lasiewski et al, 1970). T h e relatively high values evident in these birds all seem to reflect relatively low metabolic levels (see below regarding metabolic level of western plumed pigeons) as well as excellent capacities for effecting evaporation.…”

Abstract-1 . Standard ferruginea) averages 0.88 of eva~orative water loss for metabolic rate of western plumed pigeons (Lophophaps ml 0, (g hr)-I during summer. This rate and the rate by these birds at 2S°C are well below levels anticipated birds .of comparable size (81 g).2. Summer and late fall birds did not have significantly different minimal thermal conductances, the means for both approximating 1.8 kcal (m2 hr "C)-I. 3. A relatively low level of metabolism and effortless evaporative cooling restrict the caloric burden for western plumed pigeons in the hot and arid regions of northwestern Australia where these birds live. Other pigeons closely associated with hot and arid environments also have relatively low metabolic rates.

SUMMARY Over the past two decades, comparative biological analyses have undergone profound changes with the incorporation of rigorous evolutionary perspectives and phylogenetic information. This change followed in large part from the realization that traditional methods of statistical analysis tacitly assumed independence of all observations, when in fact biological groups such as species are differentially related to each other according to their evolutionary history. New phylogenetically based analytical methods were then rapidly developed, incorporated into `the comparative method', and applied to many physiological, biochemical, morphological and behavioral investigations. We now review the rationale for including phylogenetic information in comparative studies and briefly discuss three methods for doing this(independent contrasts, generalized least-squares models, and Monte Carlo computer simulations). We discuss when and how to use phylogenetic information in comparative studies and provide several examples in which it has been helpful, or even crucial, to a comparative analysis. We also consider some difficulties with phylogenetically based statistical methods, and of comparative approaches in general, both practical and theoretical. It is our personal opinion that the incorporation of phylogeny information into comparative studies has been highly beneficial, not only because it can improve the reliability of statistical inferences, but also because it continually emphasizes the potential importance of past evolutionary history in determining current form and function.

“…Occasionally, periods of extremely hot weather cause catastrophic mass mortality events, sometimes involving thousands of individuals [26,27]. Even at air temperature (T air ) below avian T b, metabolic heat gain, or heat gained from solar radiation, means that birds must frequently dissipate excess heat via evaporative and non-evaporative mechanisms, such as panting/gular flutter and wing-drooping, respectively [14,[28][29][30]. The demands of heat dissipation behaviour (HDB) can lead to trade-offs that have potentially far-reaching implications for body condition, survival and reproduction [13,31,32].…”
