Perspective on eastern migration studies: Stopover ecology of migratory landbirds in the Gulf Coast region

Abstract

Millions of Nearctic-Neotropical landbirds move through the coastal habitats of the Gulf of Mexico each spring and autumn as they migrate across and around the Gulf. Migration routes in the Gulf region are not static and they shift year to year and season to season according to prevailing wind patterns. Using data from field and radar studies, we mapped patterns of migration movement and landfall in the Gulf of Mexico region. Map categories include coastal areas where migrant numbers are consistently high, consistently common, sporadically common-abundant, sporadically common, or sparse. Weather surveillance radar data indicates that habitats along the Northwest Gulf Coast are consistently used each year.
