摘要
Capsule The spatio-temporal schedule provided by geolocators suggests that a pair of Barn Swallows could have remained together during the non-breeding period. Data from four birds, of which two were a breeding pair, showed winter quarters from West to Central Africa. The tracks of the paired individuals coincided both spatially and temporally at a scale of <200 km throughout the non-breeding period, in contrast to the tracks of an unpaired male and female from the same region.
