Thus, opportunities for conservation exist on both breeding and wintering grounds.
For both breeding seasons, none of the goats exposed to non-stimulated bucks kidded.
The moral patients are the laboratory animals, both breeding stock held by the animal supplier, and experimental animals in laboratories.
Mean hourly nest temperature, as well as mean minimum and mean maximum nest temperature, differed significantly between southern ground-hornbill nests in both breeding seasons.
Molecular analyses of major gene interactions have potential to contribute to both breeding for resistance and improved understanding of virulence impacts on pathogen fitness.
We suggest that landscape-scale conservation of bird functional diversity in both breeding and wintering seasons would increase opportunities for biological control of pest insects in mountain forests.
A great deal of work has also been done on the species' ecological niche in both breeding and wintering warbler assemblages, particularly in the areas of foraging ecology and behavior (Morse 1968, 1976a, 1989a, Katusic-Malmborg and Willson 1988).
Furthermore, both breeding and non-breeding individuals participate in these groups; nesting birds will leave nests for short periods of time to join calling assemblages that are traveling through their territories.
Both breeding and non-breeding individuals gather in loose assemblages of 3-12 individuals that travel together through the forest, calling and flying at one another (see Social and Interspecific Behavior).
The species appears not to defend foraging habitat as it is widely documented to forage regularly in large flocks of thousands in British Columbia in both breeding season and migration (Udvardy 1954) and with other swifts and swallows (Joblin 1955; Lowther and Collins 2002).
To halt these population declines, Professor Bairlein argues it is essential that we preserve and restore habitats on both breeding and nonbreeding areas, and that we must stop the illegal killing of birds along their migration routes.
