Breeding biology of the Northern Pintail Anas acuta at the edge of its southwestern Palearctic range

One of the most southern breeding sites of the Northern Pintail Anas acuta in the SW Palearctic is in the Guadalquivir marshes (southwest Spain), part of which includes Donana National Park. Breeding was recorded in 45.7% out of 46 years and was more frequent in those seasons in which the preceding...
