Pipits and Wagtails
Per (Department of Systematic Zoology Alstrom, Zetterstrum
Wagtails are noted for their bold plumage patterns and extensive racial variation. Pipits are a large and difficult group which invariably causes vexation to birders on both sides of the Atlantic. This guide covers the 26 species of northern hemisphere pipits and wagtails in detail. It treats identification in the field and in the hand, and includes colour plates, detailed distribution maps and sonograms of songs and calls.
