Zwergtäubchen Columbina minuta

Small, inconspicuous dove of savannas and open grassland with scattered low bushes and palmettos; also found locally in cane fields and pastures. Usually found in pairs or small groups, sometimes associating with other ground doves. Both sexes are rather plain overall, with diagnostic purple marks on the back, although the color is often hard to see. The female can be easily confused with the much commoner Ruddy Ground Dove, which also has a plain breast, but the Ruddy Ground Dove is larger and warmer brown overall; also note vocal differences.
