The file contains position of barn swallows Hirundo rustica (n=19). For position determination during migration cycle, we used light-level locators (type Intigeo-P55B1). Fieldwork was carried out in the period 2013-2015 in South Bohemia (48°59'6.619"N, 14°46'48.355"E), Czech Republic. For position determination we used R statistical package GeoLight 2.0.0, when we excluded the period ± 15-21 days around each equinox
