It receives the popular names of rolinha-carijó, Fogo-pagô (onomatopoeic), rol-pedrês, rolinha-rattlesnake, felix-cafofo (Paraíba), paruru and chicken-of-God. In the northernmost region of the Brazilian Northeast, precisely in the interior of the states of Rio Grande do Norte, Paraíba and Pernambuco, Columbina squammata is called by local residents as a rattlesnake or a rattlesnake due to the plumage pattern resembling the snake's scales. rattlesnake ( Crotalus durissus). In addition, the sound that the bird makes when flying resembles the sound of the rattle of the snake Rattlesnake.

The Columbina squammata is a dove of generally discreet habits, that walks in couples or small groups by the edges of forests, savannahs, orchards, parks and other types of vegetation, excluding the very open or very closed. Its silence is only broken by the vocalization , which the bird only emits perched in well-hidden places, and by the noise produced by the wings when the bird takes flight, resembling a moan. In the Southeast it is considered as a skittish species, being much more heard than seen in cities like Campinas or Ribeirão Preto, but it is curious to note that in Brasília or Goiânia the fire-out is much closer to people, scratching on sidewalks in the same way. than the purple dove (Columbina talpacoti).

Ornithologists and bird watchers in the state of São Paulo have been reporting a certain decline in the populations of this species. Many attribute this decline to competition with the flocked pigeon (Zenaida auriculata), which has been increasing its distribution and abundance.

Breeding[]
