The Zapata wren (Ferminia cerverai ) is a medium-sized grayish-brown bird that lives in dense shrubs of the Zapata Swamp, Cuba. It is the only member of the monotypical genus Ferminia, which is endemic to Cuba and endangered. This species was first described in 1926 by Thomas Barbour and named after its co-discoverer, Fermín Zanón Cervera.
Measuring about 16 centimetres (6.3 in) in length, it is brown overall, though striped with black and with grayish underparts. Its tail is long. The bird's song is similar to that of the house wren, in that it is high-pitched and loud, described as a "musical warble preceded by guttural note, given in series of three or four phrases."
