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 …

Population declines are often attributed to either habitat change or increased predation
rates, without a full consideration of the potential for these two factors to interact. This may …

The voices of birds have always been a source of fascination. Nature's Music brings together
some of the world's experts on birdsong, to review the advances that have taken place in our …

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 …

The evolutionary causes of small clutch sizes in tropical and Southern Hemisphere regions
are poorly understood. Alexander Skutch proposed 50 years ago that higher nest predation …

Predation on dependent offspring (ie, offspring that depend on parents for care) forms a
critical source of natural selection that may shape a diversity of life history traits. Selection …

Nestling birds solicit food from adults by using begging displays that appear paradoxically
costly and wasteful. Theoretical work suggests that the evolution of such exuberant offspring …

Habitat loss and fragmentation have been identified as important factors in the decline of
grassland bird populations. However, population declines are apparent even in prairie …

I review the evidence that organisms have adaptations that confer difficulty of detection by
predators and parasites that seek their targets primarily using sensory systems other than …
