The Cuban grassquit (Phonipara canora) is a small bird in the tanager family Thraupidae. It is endemic to Cuba. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, subtropical or tropical dry shrubland, and heavily degraded former forest.
The Java sparrow is about 15 to 17 cm (5.9 to 6.7 in) in length from the beak to its tip of tail feathers. Although only about the size of a house sparrow, it may be the largest species in the estrildid family. The adult is unmistakable, with its grey upperparts and breast, pink belly, white-cheeked black head, red eye-ring, pink feet and thick red bill.
