Gnatcatchers are tiny relatives of wrens, native only to the New World. Most are resident throughout their range, but the Blue-Gray Gnatcatcher migrates south from its breeding range in the USA into Mexico and Southern USA. These birds all hail from the family Polioptilidae and genus Polioptila, which translates from the Greek words polios, meaning “grey”, and ptilon for “plumage”.
The four species shown in the galleries below are all the members from the clan found in the USA. Central and South America host two other genera in this family. Birds from the genus Microbates and Ramphocaenus are similarly small birds known as gnatwrens.
