The Zapata sparrow (Torreornis inexpectata) is a medium-sized grey and yellow bird that lives in the grasslands of the Zapata Swamp and elsewhere on the island of Cuba. Measuring about 16.5 centimetres (6.5 in) in length, it is grey and yellow overall with a dark reddish-brown crown and olive-grey upperparts. The Zapata sparrow is confined and endemic to Cuba. It was discovered by Spanish zoologist, Fermín Zanón Cervera in March 1927 around Santo Tomás in the Zapata Swamp and formally described by American herpetologist Thomas Barbour and his compatriot, ornithologist James Lee Peters in 1927.
