What is "motacillidae"

The Motacillidae are a family of small passerine birds with medium to long tails. There are around 65 species in 6 genera and they include the wagtails, longclaws and pipits. The longclaws are entirely restricted to the Afrotropics, and the wagtails are predominantly found in Europe, Africa and Asia, with two species migrating and breeding in Alaska. The pipits have the most cosmopolitan distribution, being found across mostly in the Old World but occurring also in the Americas and oceanic islands such as New Zealand and the Falklands. Two African species, the yellow-breasted pipit and Sharpe's longclaw are sometimes placed in a separate seventh genus, Hemimacronyx, which is closely related to the longclaws.
