Biotic interactions are believed to play a role in the origin and maintenance of species
diversity, and multiple hypotheses link the latitudinal diversity gradient to a presumed …

ABSTRACT A growing body of work suggests that breeding birds have a significant capacity
to assess and respond, over ecological time, to changes in the risk of predation to both …

Summary 1 Demographic data from both breeding and non‐breeding periods are needed to
manage populations of migratory birds, many of which are declining in abundance and are …

Estimates of the incidence of major classes of parental care by birds are drawn from
classical studies that preceded both the publication of a massive secondary literature and …

Behavioral Ecology of Tropical Birds, Second Edition provides the most updated and
comprehensive review on the evolution of behavior in tropical landbirds. The book reviews …

Alexander Skutch hypothesized that increased parental activity can increase the risk of nest
predation. We tested this hypothesis using ten open-nesting bird species in Arizona, USA …

Correlations between the amount of energy received by an assemblage and the number of
species that it contains are very general, and at the macro-scale such species–energy …

Nest predation is a key source of selection for birds that has attracted increasing attention
from ornithologists. The inclusion of new concepts applicable to nest predation that stem …

Life history theory predicts that parents should value their own survival over that of their
offspring in species with a higher probability of adult survival and fewer offspring. We report …

Avian life history theory has long assumed that nest predation plays a minor role in shaping
reproductive strategies. Yet, this assumption remains conspicuously untested by broad …
