Biology and conservation of the endangered Bahama Swallow (Tachycineta cyaneoviridis)

Genetic population structure and dispersal of two North American woodpeckers in ephemeral habitats
… estimate the dispersal dynamics of black-backed woodpeckers (Picoides arcticus), a fire specialist, and compared these patterns to hairy woodpeckers (Picoides villosus), a generalist. I then examined how frequent colonization of ephemeral habitat patches versus stable migration among static …
