Our understanding of migratory birds' year‐round ecology and evolution remains patchy
despite recent fundamental advances. Periodic reviews focus future research and inform …

Nest predation is an important factor in the ecology of passerines and can be a large source
of mortality for birds. I provide an overview of factors affecting nest predation of passerines in …

Food limitation is generally thought to underlie much of the variation in life history traits of
birds. I examined variation and covariation of life history traits of 123 North American …

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 …

Recognition and analysis of spatial autocorrelation has defined a new paradigm in ecology.
Attention to spatial pattern can lead to insights that would have been otherwise overlooked …

Recent declines in Neotropical—Nearctic migrant songbird populations are often attributed
to events during the nonbreeding season, such as tropical habitat conversion and drought …

The nature and extent of population regulation remains a principal unanswered question for
many types of organisms, despite extensive research. In this paper, we provide a new …

Summary 1 Identifying the habitat features that influence habitat selection and enhance
fitness is critical for effective management. Ecological theory predicts that habitat choices …

1. The distribution of individuals among habitats and their relative success in those habitats
can have important consequences for population dynamics. To examine these processes for …

Abundances of forest birds in an unfragmented, undisturbed, and relatively mature
temperate deciduous forest at the Hubbard Brook Experimental Forest, New Hampshire …
