The sora (Porzana carolina) is a small waterbird of the family Rallidae, sometimes also referred to as the sora rail or sora crake. The genus name Porzana is derived from Venetian terms for small rails, and Carolina refers to the Carolina Colony. "Sora" is probably taken from a Native American language. Adults are 7.5- 11.8 inches long with dark-marked brown upperparts, a blue-grey face and underparts, and black and white barring on the flanks. They have a short thick yellow bill, with black markings on the face at the base of the bill and on the throat. Sexes are similar, but young soras lack the black facial markings and have a whitish face and buff breast. The sora can be spotted in the COSA during migration, so has been seen from April to May and in October.
