- Summary:
- During this study, birds that are closely related and morphologically similar but who have thermally dissimiliar habitats were studied. These are the Palila, a bird that is confined to the cool, montane forests of the island of Hawaii, and the Laysan Finch that is restricted to the low, treeless atoll of Laysan Island. Since significant thermoregulatory differences exist in similar species from dissimlar climates, this, together with the fact that avian basal metabolic rate (BMR) is climatically adaptive, suggests that physiological capacity may play a greater role in determining bird distribution than was generally believed. As a result, thermoregulatory studies of closely related species from differing climates, such as the Palila and the Laysan Finch, were done in an effort to resolve this issue.
