Conservation efforts are most effective when we have complete demographic information for
a species of concern. Nevertheless, fundamental gaps in our knowledge of demography still …

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

The food value theory of territoriality predicts an inverse relationship between territory size
and food density. However, several non‐mutually exclusive hypotheses can explain this …

The conservation of species with declining populations requires information on population
demography and identification of factors that limit population growth. For landbird species …

From 1995 to 1999, we mist-netted birds in regenerating clearcuts within a primarily forested
landscape of West Virginia and Virginia to determine the extent that both resident and …

Environmental variation along elevational gradients can strongly influence life history
strategies in vertebrates. We investigated variation in life history patterns between a horned …

Fecundity is fundamental to the fitness, population dynamics, conservation, and
management of birds. For all the efforts made to measure fecundity or its surrogates over the …

Brood-parasitic young are reared in the nests of different species and can derive no genetic
benefit from the survival of host offspring. However, although the nestlings of many parasitic …

Recent population declines among bird species that breed in early-successional shrubland
habitats in the eastern United States have been associated with declines in habitat …

The consequences of climate change for ecosystem structure and function remain largely
unknown. Here, I examine the ability of climate variation to explain long‐term changes in …
