Physiological variation in amethyst sunbirds (Chalcomitra amethystina) over an altitudinal gradient in winter.

The Journal of experimental biology - 1 Feb 2009

Lindsay Claire V, Downs Colleen T, Brown Mark

Abstract excerpt

Flexibility of metabolic rates within a species allows for the colonization of different habitats along an altitudinal and thus temperature gradient. The distribution range of amethyst sunbirds (Chalcomitra amethystina) within southern Africa includes an altitudinal gradient from the Drakensberg to the coast of KwaZulu-Natal. We expected that over this altitudinal gradient amethyst sunbirds would exhibit...
