Systematic notes on Asian birds. 31. Eastern races of the barn swallow Hirundo rustica Linnaeus, 1758

Abstract

The types of two Far-eastern forms of barn swallow Hirundo rustica saturata Ridgway, 1883 and H. r. mandschurica Meise, 1934 are compared. A significant difference in the colour of the underparts is confirmed and the recognition of mandschurica is recommended
