Distribution‐wide effects of climate on population densities of a declining migratory landbird
Summary Increases in global temperatures have created concern about effects of climatic variability on populations, and climate has been shown to affect population dynamics in an increasing number of species. Testing for effects of climate on population densities across a species’ distribution allow...

Summary Increases in global temperatures have created concern about effects of climatic variability on populations, and climate has been shown to affect population dynamics in an increasing number of species.

Using autoregressive population models, we tested for effects of the North Atlantic Oscillation (NAO) and the El Niño Southern Oscillation (ENSO) on annual population densities of a North American migratory landbird, the yellow‐billed cuckoo Coccyzus americanus , across the species’ breeding distribution over a 37‐year period (1966–2002).
