Grassquits are small, seed-eating tanagers found in the American tropics and West Indies, known for their distinctive songs and courtship displays. Males perform intricate display flights for courtship, which can include wing vibrations and unique calls. These include the "johnny jump-up" flight of the blue-black grassquit and the wing-vibrating dance of the yellow-faced grassquit. Male grassquits often have striking plumage, while females are duller, and they typically build domed, grass-lined nests low in bushes or grass tussocks. They are common in weedy fields, grasslands, savannas, and the edges of woods across Central and South America and the Caribbean.
