Ruddy Ground Dove
Columbina talpacoti
Small, well-named ruddy dove of humid open and semi-open areas, often in villages and even towns, where sometimes perches on wires. Often in groups, sometimes even a hundred birds, which flush explosively from underfoot. Male is ruddy overall (but much paler in West Mexico); female is plain grayish brown overall, lacking scaly breast of slightly smaller Common Ground Dove. Like other ground doves, both sexes of Ruddy show bright rusty wing patches in flight.

分布与栖息地
Adapts to artificial environments created by human action. Lives in open areas; the deforestation facilitated its expansion, especially in the areas formed to pasture or grain farming. They entered the big cities in the southeast and midwest regions of Brazil.<p>Very aggressive with each other, although they can form groups, they compete for food and defend territories using one of the wings to strike hard at the opponent. The males are more bellicose. In disputes or when they sunbathe, lying on their side on the ground and with the wing stretched upwards, they show the large area of black feathers under the wing.<p>Bird watchers in the south-central part of the United States have been observing a “replacement” of this species by another pigeon, the Zenaida auriculata, also known as dove-of-band, or amargosinha eared dove . The latter species has been conquering the urban environment more and more effectively and is apparently competing with the dove, which is already less frequent than the flock pigeon in most cities in the interior of São Paulo.<p>In any case, this friendly and even naive species is far from disappearing from the backyards of our houses and from the squares and gardens of our cities, even if they are in large buildings.
