Top 20 Most Common Bird in Oaxaca

The medium-sized, distinctively patterned white-winged Doves practically live on Saguaro cactus, consuming its nectar, pollen, fruit, and seeds. In fact, they are so dependent on this plant that they match their migration schedule to its fruiting schedule. White-winged Doves were heavily hunted in Texas in the 20th century and their population dropped from 12 million to fewer than 1 million by 1939. Since then proactive hunting management and the species ability to adapt to urban living has helped their numbers rebound.

The inca Dove is a small, compact dove with distinctive pale gray plumage and a long tail. It is found in a wide range of habitats, including urban areas, deserts, and grasslands throughout the southwestern United States and northern Mexico. The Inca Dove feeds mainly on seeds, and their cooing call is a common sound in their habitats. They are known for their fast, bouncy flight and their tendency to mate for life.

The turkey Vulture is a common sight, especially around roads, where they keep a sharp eye out for roadkill. Seeing these large birds in the sky can often make you take a second look to see if it’s an eagle or a hawk. Here’s one quick way to tell the difference. When in flight, a turkey Vulture will circle unsteadily, with its wings lifted to make a V shape. Though they are not appreciated, they do the dirty work of the animal kingdom by cleaning up the countryside as they scavenge.

The great Kiskadee is a large bird with bold markings that make this flycatcher easily recognizable. is a bright-colored bird that prefers woodland habitats close to water or open areas. It eats a lot of insects, but also forages for seeds and berries and is known to dive into shallow water for small fish.

The white-throated towhee (Melozone albicollis) is a species of bird in the family Emberizidae that is endemic to Mexico. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude shrubland.

Frequent in urban environments and human-created habitats such as parks and backyards, the little house Finch is known for its loud but pleasant, cheerful singing. It feeds on the ground, mostly on seeds, berries, and other plant material. This bird is highly sociable and very adaptable. It often visits feeders.

A common visitor of birdhouses or anywhere with birdseed, the lesser Goldfinch is a small, notch-tailed bird that enjoys gardens and open wooded areas. Its size has made it commonly overlooked, but listen out for its charming, chiming song. Social birds, they are often seen in large groups of hundreds traveling together at a time.

The vermilion Flycatcher is a bright species of bird found in many open habitats and rarely seen on the ground. These birds sit on a perch until they're ready to take wing and feed on a variety of insects midflight. The vermilion Flycatcher is not a threatened species, but urbanization that eliminates some of thier natural breeding grounds could affect populations.

An adult tropical kingbird is 22 cm (8.7 in) long, weighs 39 g (1.4 oz) and has a wingspan range of 38–41 cm. The head is pale gray, with a darker eye mask, an orange crown stripe, and a heavy gray bill. The back is grayish-green, and the wing and forked tail are brown. The throat is pale gray, becoming olive on the breast, with the rest of the underparts being yellow. The sexes are similar, but young birds have pale buff edges on the wing coverts. Tropical Kingbirds appear to be monogamous. In most parts of the species' range, they are permanent residents and remain together in pairs year-round.(Sibley 2014) The call is a high-pitched twittering trill, tree-e-e-e-e-e-e, with a more complex version sung by the male at dawn. Their breeding habitat is semi-open areas with trees and shrubs, including gardens and roadsides. Tropical kingbirds like to observe their surroundings from a prominent open perch, usually high in a tree, undertaking long flights to acrobatically catch insects in mid-air (hawking), sometimes hovering to pick food off vegetation (gleaning). They also eat some fruit from such diverse species as tamanqueiro (Alchornea glandulosa), the Annonaceae, Cymbopetalum mayanum and gumbo-limbo (Bursera simaruba); foraging for these even in disturbed habitat. As they keep mainly to the upper levels of trees, they find little profit in following mixed-species feeding flocks in the understory. These birds aggressively defend their territory against intruders, even much larger birds such as magnificent frigatebirds, toucans, caracaras or hawks. In a study in Parque Nacional de La Macarena of Colombia, parasitism by microfilariae and trypanosomas (presumably T. everetti) was infrequently recorded in tropical kingbirds. The male and female inspect potential sites together before selecting a site, typically a fork or crotch high in a tree (up to 66 feet high) but sometimes just a few feet above water.(Sibley 2014) The female builds a bulky, sloppy-looking, shallow nest of vines, rootlets, twigs, weeds, and grasses; it is unlined or lined with hair. Nests average about 5.2 inches across and 3 inches tall, with interior cup about 3 inches across and 1.6 inches deep. The female incubates the typical clutch of two to four eggs for approximately 16 days, and the nestlings fledge in another 18 or 19 days. The eggs are whitish or pale pink with variable amounts of dark blotching. The tropical kingbird is one of the most widespread and conspicuous inhabitants of open forest, forest edge, scrub and agricultural land from the southwestern United States south to Argentina (Jahn, Stouffer, & Chesser, 2013). As a result, the bird is considered as being of Least Concern and their population is increasing, according to the IUCN. According to Partners in Flight, global estimates of tropical kingbird breeding population is around 200 million. They rate the species as 4 out of 20 on the continental concern scale, indicating that this species is of low conservation concern.

Just as its name implies, the little house Sparrow socializes with humans more than any other bird species. Able to adapt and thrive in almost any habitat, excluding the extremes such as deserts and mountain peaks, this species was once restricted only to North Africa and Eurasia but now is found across the globe. Unfortunately, this opportunistic eater is not completely harmless—it can cause considerable damage to crops.

In appearance, the social flycatcher resembles a smaller boat-billed flycatcher or great kiskadee. The adult is 16–18 cm (6.3–7.1 in) long and weighs 24–27 g (0.85–0.95 oz). The head is dark grey with a strong white eyestripe and a usually concealed orange to vermilion crown stripe. The upperparts are olive-brown, and the wings and tail are brown with only faint rufous fringes. The underparts are yellow and the throat is white. Young birds have a paler eye mask, reduced crown stripe, and have chestnut fringes to the wing and tail feathers. The call is a sharp peeurrr and the dawn song is a chips-k’-cheery. As the specific epithet similis (Latin for "the similar one") indicates, this species looks much like its closest living relative the rusty-margined flycatcher (Myiozetetes cayanensis), and also like the white-bearded flycatcher (Phelpsia inornatus), white-ringed flycatcher (Conopias albovittatus) and lesser kiskadee (Pitangus/Philohydor lictor). In fact, except at close range, these are all but indistinguishable from appearance alone. They and the two larger similar species mentioned above share much of their range. Though they all are apparently fairly close relatives, the group to which they seem to belong also includes species with rather different head-pattern, like the grey-capped flycatcher which also belongs to Myiozetetes.

The berylline hummingbird (Saucerottia beryllina) is a medium-sized hummingbird. It is 8–10 cm long, and weighs 4-5 g. Adults are colored predominantly metallic olive green with a rusty gray lower belly. The tail and primary wings are rufous in color and slightly forked. The underwing is also rufous. The bill of the male is straight and very slender. It is very dark red in coloration, almost black. The female is less colorful than the male. The breeding habitat is in forests and thickets of western Mexico to central Honduras in Central America. It regularly strays to southeasternmost Arizona in the United States where it occasionally breeds–(the Madrean sky islands). The female builds a nest in a protected location in a shrub or tree. Females lay two white eggs. This hummingbird is essentially non-migratory. These birds feed on nectar from flowers and flowering trees using a long extendable tongue or catch insects on the wing. This species was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the berylline hummingbird was moved to the resurrected genus Saucerottia.

Although quite dapper in appearance, the black Vulture's name comes from the Latin vulturus meaning “tearer" and that is just what that hooked beak is for. These birds are highly social, with fierce family loyalty and will share food with relatives and with their young long after the babies have fledged. Because they lack a voice box, their calls are limited to grunts and hisses.

The Bewick's wren has an average length of 5.1 inches (13 cm) an average weight of 0.3 to 0.4 ounces (8 -12 g), and a wingspan of 18 cm. Its plumage is brown on top and light grey underneath, with a white stripe above each eye. Its beak is long, slender, and slightly curved. Its most distinctive feature is its long tail with black bars and white corners. It moves its tail around frequently, making this feature even more obvious for observers. Juveniles look similar to adults, with only a few key differences. Their beaks are usually shorter and stockier. In addition, their underbelly might feature some faint speckling. Males and females are very similar in appearance.

The medium-sized great-tailed Grackle is notable for its long tail, shaped like a V, and deep black coloring offset by bright yellow eyes. This loud bird can be easily found just by following the sharp sounds of its calls and shrieks. Males in particular shriek and ruffle up their feathers to defend their territory or if they feel threatened.

The grey silky-flycatcher or grey silky (Ptiliogonys cinereus), is a species of bird in the family Ptiliogonatidae. It is usually found only in Guatemala and Mexico, but vagrants have turned up in the southern United States. It is found in montane forest and adjacent scrub, both mesic and xeric.

The blue-gray gnatcatcher or blue-grey gnatcatcher (Polioptila caerulea) is a very small songbird, 10–13 cm (3.9–5.1 in) in length, 6.3 in (16 cm) in wingspan, and weighing only 5–7 g (0.18–0.25 oz). Adult males are blue-gray on the upperparts with white underparts, have a slender dark bill, and a long black tail edged in white. Females are less blue, while juveniles are greenish-gray. Both sexes have a white eye ring. The blue-gray gnatcatcher's breeding habitat includes open deciduous woods and shrublands in southern Ontario, the eastern and southwestern United States, and Mexico. Though gnatcatcher species are common and increasing in number while expanding to the northeast, it is the only one to breed in Eastern North America. Both parents build a cone-like nest on a horizontal tree branch, and share feeding the young. The incubation period is 13 days for both sexes, and two broods may be raised in a season. These birds migrate to the southern United States, Mexico, northern Central America-(Belize, Guatemala, and Honduras), Cuba, Bahamas, Turks and Caicos Islands, and the Cayman Islands. They forage actively in trees or shrubs, mainly eating insects, insect eggs and spiders. They may hover over foliage while snatching prey (gleaning), or fly to catch insects in flight (hawking). The tail is often held upright while defending territory or searching for food.

Adults have a gray head with slightly darker cheeks; a dark unforked tail with a buffy fringe and gray-olive underparts. They have a pale throat and deep yellow lower breast. Juveniles are duller and have pale edges on their wings. Measurements: Length: 8.3-9.1 in (21-23 cm) Weight: 1.6 oz (45 g) Wingspan: 41 cm

It has a total length of 50–65 cm (20–26 in) and a wingspan of 120–132 cm (47–52 in). Weight is 0.9-1.6 kg (2-3.5 lbs), averaging 1,348 g (2.972 lb) in 7 birds from Tierra del Fuego. Individuals from the colder southern part of its range average larger than those from tropical regions (as predicted by Bergmann's rule) and are the largest type of caracara. In fact, they are the second largest species of falcon in the world by mean body mass, second only to the gyrfalcon. The cap, belly, thighs, most of the wings and tail-tip are dark brownish, the auriculars, throat and nape are whitish-buff, and the chest, neck, mantle, back, uppertail-coverts, crissum (the undertail coverts surrounding the cloaca) and basal part of the tail are whitish-buff barred dark brownish. In flight, the outer primaries show a large conspicuous whitish-buff patch ('window'), as in several other species of caracaras. The legs are yellow and the bare facial skin and cere are deep yellow to reddish-orange. Juveniles resemble adults, but are paler, with streaking on the chest, neck and back, grey legs, and whitish, later pinkish-purple, facial skin and cere. It can be separated from the similar northern caracara by its more extensive barring on the chest, brownish and often lightly mottled/barred scapulars (all blackish in northern), and pale lower back with dark barring (uniform blackish in northern). Individuals showing intermediate features are known from the small area of contact in north-central Brazil, but intergradation between the two species is generally limited.

The foraging yellow-rumped Warbler is quick-moving and appealingly colored. Both male and female are a sharp gray, with white on their wings and flashes of yellow on their rump (as the name suggests), sides, and face. Most striking about this bird is the large groups of them that spread across North America in the autumn season.
