Habitat-specific foraging strategies in Australasian gannets
Knowledge of top predator foraging adaptability is imperative for predicting their biological response to environmental variability. While seabirds have developed highly specialised techniques to locate prey, little is known about intraspecific variation in foraging strategies with many studies deriving information from uniform oceanic environments. Australasian gannets (Morus serrator) typical...
متن کاملStopover Ecology and Habitat Use of Migratory Wilson's Warblers
--The conservation of long-distance migratory songbirds is complicated by their life-history characteristics and the spatial scales that they traverse. Events during migratory stopovers may have significant consequences in determining the population status of migratory songbirds. Using Wilson's Warbler (Wilsonia pusilla) as a focal species, we investigated effects of age and sex on stopover par...
متن کاملHabitat Associations of Song Characteristics in Phylloscopus and Hippolais Warblers
Ai•sTRACT.--Bird-song functions, such as mate attraction, species recognition, and territory defense, are closely linked to individual fitness. Thus, habitat characteristics that affect song transmission and degradation should exert a strong influence on the evolution of song attributes. Whereas different acoustic environments may influence the evolution of song characteristics, factors such as...
متن کاملDetermining habitat quality for species that demonstrate dynamic habitat selection
Determining habitat quality for wildlife populations requires relating a species' habitat to its survival and reproduction. Within a season, species occurrence and density can be disconnected from measures of habitat quality when resources are highly seasonal, unpredictable over time, and patchy. Here we establish an explicit link among dynamic selection of changing resources, spatio-temporal s...
