Breeding (1): Timing of Breeding

Abstract

With regard to the timing of breeding in birds, “by far the most important ultimate factor for nearly all species of birds is the availability of an adequate food supply…. Each species has therefore evolved the timing of its breeding so that it coincides with a maximum availability of its species-specific food” (Immelmann 1971). An exception to this maybe the Double-banded Courser Smutsornis africanus in southern Africa, since it breeds throughout the year, regardless of environmental conditions (Maclean 1967b). “Every species is apparently adjusted to breed at the time of year at which it can raise its young most efficiently” (Immelmann 1971).
