Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

Reports of declines in abundance and biomass of insects and other invertebrates from
around the world have raised concerns about food limitation that could have profound …

Predator effects on prey demography have traditionally been ascribed solely to direct killing
in studies of population ecology and wildlife management. Predators also affect the prey's …

Human disturbance drives the decline of many species, both directly and indirectly.
Nonetheless, some species do particularly well around humans. One mechanism that may …

The rate of reproduction, age at maturity and longevity vary widely among species. Most of
this life-history variation falls on a slow-fast continuum, with low reproductive rate, slow …

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 …

Birds inhabiting hot, arid regions are among the terrestrial organisms most vulnerable to
climate change. The potential for increasingly frequent and intense heat waves to cause …

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 …

Oviposition-site choice is a major maternal effect by which females can affect the survival
and phenotype of their offspring. Across oviparous species, the ultimate reasons for females' …

When approached by humans, virtually all species flee, but we lack an understanding of the
factors that influence flight response among species. Understanding this variation may allow …
