Motacillidae

This bird family contains small passerines, such as Wagtails, Longclaws and Pipits. They are divided over six genera, two of which show hybridization (Motacilla and Anthus).

 

Anthus

A hybrid between Meadow Pipit (A. pratensis) and Water Pipit (A. spinoletta) was confirmed by genetic analysis (Bures, Nadvornik & Saetre, 2002).

Motacilla

A few Russian studies report hybridization between (sub)species or populations of Wagtails. The complicated taxonomy of these birds hinders interpretation of the results. In the Yamal Peninsula, White Wagtails (M. alba) are separated into tundra and forest populations. The zone between these habitats may contain hybrids (Ryzhanovskii, 2006). In addition, two subspecies of Siberian White Wagtails (M. a. alba and M. a. personata) interbreed, resulting in introgression (Semenov, Yurlov & Khaydarov, 2010).
