The scaled dove (Columbina squammata), also known as scaly dove, Ridgway's dove, mottled dove, and South American zebra dove, [2] is found in Brazil, Bolivia, Argentina, Colombia, French Guiana, Paraguay, Trinidad and Tobago, and Venezuela. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and heavily degraded former forest.
It measures between 18 and 22 centimeters in length and weighs between 48 and 60 grams. [3] The species has grayish-brown upper parts and a pinkish-gray face and chest. The throat is white and the distal wing coverts are also white and form a visible white spot on the wings when they are closed. [3] The tail is dark with the tips of the rectrices being white, forming a white band on the side of the tail, noticeable when the bird is in flight. [3] The species has dark eyes, pink legs and gray beak. It has a “scaly” appearance caused by the dark edges of the feathers. The most striking feature of this species is the scaling pattern of the plumage, which provides it with efficient camouflage. When in flight you can see a white stripe at the base of the wing. Its primaries are brown in color. [3]
The etymology of the scientific names comes from Latin, with the genus Columbina meaning "dove-like" from the Latin columba (meaning "dove") and with the specific epithet squammata meaning "scaled" from the Latin squamatus (also meaning "scaled), in reference to the bird's plumage. [4]
In Brazilian Portuguese, this species has a variety of popular names, including: rolinha-carijó, Fogo-pagô (onomatopoeic), rol-pedrês, rolinha-cascavel, felix-cafofo (Paraíba), paruru and galinha-de-deus. In the Brazilian states of Rio Grande do Norte, Paraíba, and Pernambuco, this species is sometimes referred to as rolinha-cascavel, meaning "rattlesnake" due to the plumage pattern resembling the snake's scales and the sound that the bird makes when flying, which resembles the sound of the rattle of the local species of rattlesnake ( Crotalus durissus ). [3]
There are two recognized subspecies:
Columbina squammata is a dove of generally discreet habits, that walks in pairs or small groups by the edges of forests, savannahs, orchards, and other types of vegetation, while tending to avoid very open or very closed habitats. [3] It is normally silent, except when vocalizing, which the bird only does while perched in well-hidden places, and except for the noise produced by the wings when the bird takes flight. [3] In southeastern Brazil, it is considered as a skittish species, being much more heard than seen in cities like Campinas or Ribeirão Preto, but in other parts of Brazil, such as Brasília or Goiânia this species can be found much closer to people, scratching on sidewalks in the same way as its congener, the ruddy ground-dove ( Columbina talpacoti ).
Ornithologists and bird watchers in the state of São Paulo have been reporting a decline in the populations of this species, [3] potentially attributing this decline to competition with the eared dove ( Zenaida auriculata ), which has been increasing in both range and abundance. [3]
It makes a nest of twigs in the shape of a cup, usually 1 or 2 meters above the ground, but may sometimes also nest on the ground. [3] This species usually lays 2 white eggs.
It feeds on the ground, walking with its belly almost dragging on the ground. [3] When scared, it flies sharply to nearby trees. The tree species Trema micrantha is one of the favorite fruits of this species. [3]
Columbidae is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on plants, and can be taxonomically divided amongst granivores, that feed mostly on the ground on seeds, and frugivores, that feed mostly on fruits, from branches. The family occurs worldwide, often in close proximity with humans, but the greatest variety is in the Indomalayan and Australasian realms.
The rock dove, rock pigeon, or common pigeon is a member of the bird family Columbidae. In common usage, it is often simply referred to as the "pigeon", although this is the wild form of the bird; the pigeons most familiar to people are the domesticated form of the wild rock dove.
The emerald dove or common emerald dove, also called Asian emerald dove and grey-capped emerald dove, is a widespread resident breeding pigeon native to the tropical and subtropical parts of the Indian Subcontinent and Southeast Asia. The dove is also known by the names of green dove and green-winged pigeon. The common emerald dove is the state bird of the Indian state of Tamil Nadu. The Pacific emerald dove and Stephan's emerald dove were both considered conspecific.
The common ground dove is a small bird that inhabits the southern United States, parts of Central America, the Caribbean and northern South America. It is considered to be the smallest dove that inhabits the United States. As its name suggests, the bird spends the majority of its time on the ground walking but still has the ability to fly.
The white-tipped dove is a large New World tropical dove. Its scientific name commemorates the French naturalists Jules and Edouard Verreaux.
The ruddy ground dove is a small New World tropical dove. It is a resident breeder from Mexico south to Brazil, Peru and Paraguay, and northern Argentina, and on Trinidad and Tobago. Individual birds can sometimes be seen in the southwestern USA, from southern Texas to southernmost California, primarily during winter.
The scaled pigeon is a large New World tropical dove. It is a resident breeder from southern Mexico south to western Ecuador, southern Brazil, northern Argentina, and Trinidad.
The pale-vented pigeon is a large pigeon found in the tropical Americas. Formerly often placed in Columba, it actually belongs to a clade of the older New World genus Patagioenas. With its relatives it represents an evolutionary radiation extending through most of the warm-temperate to tropical Americas. Grey-hued birds, even their males generally lack iridescent display plumage, although the present species has some coppery gloss on the nape.
The blue ground dove is a small New World tropical dove. It is a resident breeder from southeastern Mexico to northwestern Peru and northern Argentina, and on Trinidad in the Caribbean.
The Tataupa tinamou is a type of tinamou commonly found in dry forest in subtropical and tropical regions in southeastern South America.
The chestnut-headed sparrow-lark or chestnut-headed finch-lark is a species of passerine bird in the family Alaudidae. It is found in eastern and north-eastern Africa. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical dry lowland grassland, and hot deserts.
The black wood pigeon or Japanese wood pigeon is a species of bird in the family Columbidae. It is found in East Asia along shorelines of the Pacific's Korea Strait, Philippine Sea and East China Sea. It is believed to be the largest representative of the genus, Columba, and has a weight of around 550 grams (1.2 lb) and an overall length of 43 cm (17 in). Its natural habitats are temperate forests and subtropical or tropical moist lowland forests. The species is in decline owing to habitat loss, habitat degradation, deforestation and hunting. This wood pigeon is endemic to the laurel forest habitat.
The plain-breasted ground dove is a species of bird in the family Columbidae. It lacks the scaled appearance to the feathers of the similar and typically more abundant common ground dove.
The Picui ground dove or Picui dove is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Brazil, Chile, Colombia, Paraguay, Peru, and Uruguay.
The white-bibbed fruit dove is a species of bird in the family Columbidae.
The Taiwan green pigeon is a bird in the family Columbidae. The species was first described by Robert Swinhoe in 1863. It is found in Taiwan and Batanes in the Philippines.
The black-cheeked gnateater is a species of bird in the family Conopophagidae endemic to Brazil. The male is distinguished by its orange crown, black face and white throat, while the female has brown plumage.
Columbina is a genus of small doves in the family Columbidae that live in the New World. They range from the southern United States through Central America and much of South America. Columbina doves are normally found in pairs or small flocks and generally occur in open country. They have maroon irides and pinkish legs. In flight, some species show a distinctive flash of rufous in the wings, while others show black-and-white wing-patterns.
