Top 20 Most Common Bird in Cochabamba

It has a total length of approximately 18 cm (7 in). It is overall ashy-brown with contrasting black lores and rufous wings. The taxon fringillarius has more black in the face and is overall more rufescent (less ashy). It is social and commonly seen in small groups. Unlike the "true" cowbirds in the genus Molothrus, this species is not a brood parasite. In contrast, the screaming cowbird is a brood parasite of the grayish baywing, and while adult screaming cowbirds are overall blackish, juvenile screaming cowbirds closely resemble grayish baywings.

The rufous Hornero is a medium-sized ovenbird, found in South America. It is recognized as the national bird in Uruguay and Argentina. Scientifically known as Furnarius rufus, you can differentiate the male from the female depending on how quickly their wings beat while they sing.

The most widely-spotted dove of South America, the small eared Dove thrives in high altitudes. You can find this dove in the scrubland of areas that are around 4500 meters above sea level. Their easy association with humans has made them acclimate more easily to urban environments and rising human population levels.

The rufous-collared Sparrow is a small songbird known for its pleasant vocalization and numerous "dialects." The songs peak at dawn and some individuals can sing continuously for half an hour. Found in a wide range of habitats and comfortable around humans, this ground-feeding bird is easily approachable. On the other hand, it's aggressive towards other birds that enter its territory. Individuals have their favorite perching spot where they appear repeatedly.

The Chiguanco thrush (Turdus chiguanco) is a species of bird in the family Turdidae. It is found in Ecuador and the Altiplano. Its natural habitats are subtropical or tropical high-altitude shrubland and heavily degraded former forest.

The sayaca tanager (Thraupis sayaca) is a species of bird in the family Thraupidae, the tanagers. It is a common resident in northeastern, central, and southeastern Brazil (Portuguese: sanhaço [sɐ̃ˈɲasu], sanhaço-cinzento [sɐ̃ˈɲasu sĩˈzẽtu]), and Bolivia, Paraguay, Uruguay, and northeastern Argentina (where they are known as celestinos or celestinas). A few are recorded from far southeastern Peru, but its status there is unclear, in part due to the potential of confusion with the very similar juveniles of the blue-grey tanager. It occurs in a wide range of open to semiopen habitats, but generally avoids the interior of dense forest (such as the Amazon). This tanager visits farmland in search of orchards and adapts readily to urban environment, as long as some arboreal cover and a supply of fruits are available. It feeds on flowers, buds, and insects, and this omnivorous lifestyle has helped it to become perhaps the most — or one of the most — common urban birds in southeastern Brazil, along with the rufous-bellied thrush.

Watch out for the small yet aggressive house Wrens; they are extremely territorial and think nothing of harassing other birds and their nestlings if they want to take their spot! They have been known to kill nestlings and even adult birds to get a nest hole they want. Once house Wrens lay eggs, the nest needs to stay below 100 degrees and above 65 degrees or the eggs will not survive—this could be the reason they are so particular about their nesting spots.

Hooded siskins are 10 to 14 cm in length. The male is largely green above and yellow below with a black head. It has a narrow yellow collar and a yellow rump. The tail is black with yellow sides to the base and the wings are black with a broad yellow band. Females are duller with a green-brown head, yellow-green breast and sides and a whitish belly. The twittering song may be uttered from a perch or in flight. It is varied and fast, and may contain imitations of other birds.

The saffron Finch is a common finch with a widespread distribution, the male is easy to spot with its bright yellow feathers. It is seen in open areas like agricultural fields and gardens. The bird tends to gather in flocks as they search for seeds. Its large range across multiple warm weather climates keeps it off the vulnerable species list.

The golden-billed saltator (Saltator aurantiirostris) is a species of saltator in the family Thraupidae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay; also the regions of the southern pantanal, along the Paraguay River. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical dry shrubland, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.

The grey-hooded parakeet is a small, slender parakeet growing to a length of about 20 cm (8 in). The upper parts are green and the flanks and underwing coverts are greenish-yellow. The forehead and crown are brownish-grey, and the chin, throat and breast are whitish-grey, sometimes with a bluish tinge at the side of the breast. The belly is green with a bluish tinge. The upper side of the long, narrow, pointed tail is green and the underside is grey. The beak is flesh-coloured, the iris is brown and the legs and feet are brownish-grey. The sexes are similar in appearance, but the male often has a more vivid grey breast, and immature birds have shorter tails.

The blue-and-white Swallow is a temperate species commonly found in open grasslands and farmlands and, in Central America, it is also common at high elevations. These birds are insectivores and will flock together around swarms of termites. Unfortunately, deforestation has started to affect wild populations, though the extent is unknown.

The creamy-bellied thrush (Turdus amaurochalinus) is a species of bird in the family Turdidae. It occurs in a wide range of wooded habitats in a large part of central and eastern South America. It is generally common, even in human altered habitats such as gardens and parks. While the plumage varies from overall greyish to brownish, and the bill from dusky to yellow, adult creamy-breasted thrushes always have distinctive blackish lores. This separates it from other similar thrushes (e.g. the pale-breasted thrush) found in its range.

The Picui ground dove (Columbina picui) is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Brazil, Chile, Colombia, Paraguay, Peru, and Uruguay. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.

The red-tailed comet is one of the largest hummingbirds, and males reaching a length of 22 cm, females up to 15 cm. The plumage of males is largely green, with a shining gorget. The head is green, while the back and rump are reddish violet. The male has a deeply forked, spectacular, long, iridescent, golden-reddish tail, longer than the length of the body, while the female has a shorter reddish-bronze tail. The species has a hoarse chattery call.

The sparkling violetear is the largest violetear at 13 to 15 cm (5–6 in) long. Male birds weigh 7.7 to 8.5 grams (0.27 to 0.3 oz) while females weigh from ounces 6.7 to 7.5 grams (0.24 to 0.26 oz). This hummingbird resembles the lesser violetear, but that species generally prefers more humid habitats, is obviously smaller and lacks the distinct purple-blue chest-spot and gorget of the sparkling violetear. According to one study, it has the smallest mean blood-air barrier thickness (0.183 µm) and the highest mass-specific respiratory surface area in birds (87 cm²/g).

The grey-bellied flowerpiercer (Diglossa carbonaria) is a species of bird in the family Thraupidae. It is found in the Bolivian Andes and far northwestern Argentina. Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, and heavily degraded former forest.

In Bolivia, the giant hummingbird is known in Quechua as burro q'enti, the Spanish word burro referring to its dull plumage. Members of P. gigas can be identified by their large size and characteristics such as the presence of an eye-ring, straight bill longer than the head, dull colouration, very long wings (approaching the tail tip when stowed), long and moderately forked tail, tarsi feathered to the toes and large, sturdy feet. There is no difference between the sexes. Juveniles have small corrugations on the lateral beak culmen. The subspecies are visually distinguishable. P. g. peruviana is yellowish brown overall and has white on the chin and throat, where P. g. gigas is more olive green to brown and lacks white on the chin and throat. The giant hummingbird occasionally glides in flight, a behavior very rare among hummingbirds. Its elongated wings allow more efficient glides than do those of other hummingbirds. The giant hummingbird's voice is a distinctive loud, sharp and whistling "chip".

The bare-faced ground dove (Metriopelia ceciliae) is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Chile, and Peru. Its natural habitat is subtropical or tropical high-altitude shrubland.

The blue-and-yellow tanager (Rauenia bonariensis) is a species of bird in the tanager family Thraupidae. It is found in Argentina, Uruguay, Brazil, Paraguay, Bolivia, extreme northern border Chile, and Andean Peru and Ecuador. Some southern region birds migrate northeastwards in the austral winter into eastern Bolivia and northeastern Argentina; also Paraguay where the birds are only migratory non-breeding residents. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, subtropical or tropical high-altitude shrubland, and heavily degraded former forest. This species was formerly placed in the genus Thraupis. It was moved to Pipraeidea based on the results of a molecular phylogenetic study published in 2014. It was moved to Rauenia based on the study published in 2020. It is monotypic in that genus.
