The hooded oriole (Icterus cucullatus) is a medium-sized New World oriole. The male of this species ranges in color from a bright orange to a paler yellow, with a black back, face, tail and bib, with the wing containing two white bars. The female is more of an olive color with some yellow accents. [2]
Adults have a curved bill which is completely black and white wing bars. The adult male has a deep yellowish orange head with black on the face and throat; they are black on the back, wings and tail, orange on the underparts. The adult female is olive-green on the upper parts, yellowish on the breast and belly. Their calls consist of whistling and wheets, while their song is a mixture of both.
Their breeding habitat is open areas with trees, especially palms, across the Southwestern United States and northern Mexico. The nest is a tightly woven pouch attached to the underside of a leaf or tree branch. Sometimes their nest is filled with the egg of a brown-headed cowbird which is a parasite bird that lays its eggs in other birds nests for that species to take care of.
These birds migrate in flocks south to Mexico's southwestern coast; they are permanent residents in Baja California Sur, the Mexican east coast, and Belize. Some may over-winter near feeders. They can also be found in Southern California neighborhoods, but are rare in the winter.
They forage in trees and shrubs, also feeding from flowers. It is a nectar robber because it pierces the base of the flower, and does not assist in pollination. These birds mainly eat insects, nectar and fruit, and will also visit hummingbird feeders and bird feeders for seeds.
Diet
The hooded oriole's diet consists of insects, berries, and nectar. [3] Hooded Orioles are acrobatic feeders, often hanging upside down to get the nectar from flowers and to catch their prey. [4] This species feeds on a variety of insects, but may especially favor caterpillars, beetles, wasps, and ants. Hooded orioles forage for food slowly, gathering insects from foliage in the trees and feeding on berries, along with sometimes oranges or other citrus. They also probe flowers for nectar, and may take insects there as well. They are common visitors to insect and hummingbird feeders. [5]
Voice
The song of the hooded oriole tends to be short and abrupt. The notes are rapid and lack the whistling nature of many other oriole species, and often sound nasal and whiny in nature. [6]
There is a high amount of variation both geographically and individually within the song of the hooded oriole. Each male also sings many different types of songs. The hooded oriole has been known to include mimicry in its song, notably in Arizona some individuals have included the songs of the Gila Woodpecker and the Ash-throated Flycatcher.
Common calls of the hooded oriole include a whistled wheet or sweet sound. A chatter call is given as an alarm, somewhat similar to that of the Baltimore oriole or Bullock's oriole. The individual notes of the hooded oriole's chatter are given more quickly however, and it creates a shriller sound. Juveniles commonly give a soft chut and a harsher chuck or chet, however these have also been observed being given by adults. [7]
Nesting
Males arrive at their nesting sites in the last weeks of March and set up breeding territories. The breeding season lasts from April to July in Texas, May to August in Arizona, April to mid-August in California, and May to August in Baja California.
Recent reports state that the nests are constructed and secured on the undersides of palms and banana plants. Location and structure materials vary geographically. Arizona nests are often made of grasses and located in taller trees. Meanwhile, California nests are made from palm fibers and located on the underside of palm plants. The hooded oriole's nest is basket shaped, and much deeper than its relatives. [8]
Female hooded orioles lay a clutch of 3-5 eggs. The eggs are generally white, but can range into a pale blue with darker splotches. The eggs are incubated for 12-14 days, and the nestlings take about 14 days to fledge. This species is also commonly parasitized by the brown-headed cowbird and the bronzed cowbird. [9]
There are five subspecies divided into two groups: those east of the Big Bend in Texas, which are more orange in color, and those found in New Mexico and more south, which are yellower in color. [10]
I. c. cucullatus
This subspecies is found in the Rio Grande Valley in Texas and south through Mexico to Oaxaca and Veracruz. This subspecies is very orange in color. [11]
I. c. sennetti
This subspecies occurs from the lower Rio Grande valley of Texas south along the coastal plain into Tamaulipas. This subspecies is similar in color to cucullatus but is notably paler and more yellow. [12]
I. c. igneus
This subspecies occurs in southern Mexico from East Tabasco and the Yucatán Peninsula south into Belize. This is the brightest most orange form. It has been reported that females of this subspecies may display a more greyish throat patch. [13]
I. c. nelsoni
This is the western form of this species, found from California south to North Baja California, and east into Arizona and New Mexico. This subspecies is noticeably more yellow than the others. This subspecies also has a much more slender bill, and longer wings and shorter tail. [14]
I. c. trochiloides
This subspecies is found in Baja California and Mexico. This is a yellowish-orange combo, and has a much longer and thinner bill. [15]
Icterids or New World blackbirds make up a family, the Icteridae, of small to medium-sized, often colorful, New World passerine birds. The family contains 108 species and is divided into 30 genera. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" comes from the Ancient Greek ikteros via the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques.
The Altamira oriole is a New World oriole. The bird is widespread in subtropical lowlands of the Mexican Gulf Coast and northern Central America, the Pacific coast and inland. They have since spread to southern Texas, but this was not until 1939.
The western meadowlark is a medium-sized icterid bird, about 8.5 in (22 cm) in length. It nests on the ground in open grasslands across western and central North America. It feeds mostly on bugs, but will also feed on seeds and berries. The western meadowlark has distinctive calls described as watery or flute-like, which distinguish it from the closely related eastern meadowlark. The western meadowlark is the state bird of six states: Kansas, Montana, Nebraska, North Dakota, Oregon, and Wyoming.
The Baltimore oriole is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17th-century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole Icterus bullockii, led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.
Bullock's oriole is a small New World blackbird. At one time, this species and the Baltimore oriole were considered to be a single species, the northern oriole. This bird is named after William Bullock, an English amateur naturalist.
The orchard oriole is the smallest species of icterid. The subspecies of the Caribbean coast of Mexico, I. s. fuertesi, is sometimes considered a separate species, the ochre oriole or Fuertes's oriole.
The Venezuelan troupial is the national bird of Venezuela. It is found in Colombia, Venezuela, and the Caribbean islands of Aruba, Curaçao, Bonaire, Trinidad, and Puerto Rico. Together with the orange-backed troupial and campo troupial, it was previously part of a superspecies simply named the troupial that was split.
The giant cowbird is a large passerine bird in the New World family Icteridae. It breeds from southern Mexico south to northern Argentina, and on Trinidad and Tobago. It may have relatively recently colonised the latter island. It is a brood parasite and lays its eggs in the nests of other birds.
The bronzed cowbird, once known as the red-eyed cowbird, is a small icterid.
Euphagus is a small genus of American blackbirds. It contains two extant species: Brewer's blackbird, Euphagus cyanocephalus, and rusty blackbird E. carolinus.
Audubon's oriole, formerly known as the black-headed oriole, is a New World passerine inhabiting the forests and thickets of southeastern Texas and the Mexican coast. It is the only species to have a black hood and yellow body. It is divided into four subspecies and two allopatric breeding ranges. The westernmost range extends from Nayarit south to southern Oaxaca, whereas the eastern range stretches from the lower Rio Grande valley to northern Querétaro. The most common in the western range are the subspecies I. g. dickeyae and I. g. nayaritensis; I. g. graduacauda and I. g. audubonii can be found in the eastern range. Like most Central American birds, it is not a migratory species and does not display significant sexual dimorphism. DNA analysis of the ND2 and cyt-b genes strongly suggests that I. graduacauda is most closely related to I. chrysater, the yellow-backed oriole. It is a member of the genus Icterus and therefore should not be confused with the Old World orioles.
The Martinique oriole is a species of bird in the family Icteridae. It is endemic to Martinique, French West Indies. Martinique is a part of the Lesser Antilles, and is located in the Eastern Caribbean.
The yellow-backed oriole is a species of bird in the family Icteridae.
The Saint Lucia oriole is a species of bird, in the family Icteridae and genus Icterus. It is endemic to Saint Lucia.
The black-cowled oriole is a species of bird in the family Icteridae. It is common and widespread in the Caribbean lowlands and foothills from southern Mexico to western Panama. It lives primarily in humid or semihumid forest, as well as in clearings, along forest edges, in plantations, in semi-open areas with scattered trees and bushes, and in gardens. The adult male is black, with yellow on the belly, shoulder, rump, wing lining, and crissum. The female's plumage varies depending on location. In the south of its range, it is similar to that of the male. In the north, its crown and upperparts are olive-yellow, while its face, throat, upper breast, wings, and tail are black.
The orange-backed troupial is a species of bird in the family Icteridae. It is found in Guyana, Brazil, Paraguay, and eastern Ecuador, Bolivia, and Peru. It is closely related to the Venezuelan troupial and Campo troupial, and at one time, all three were considered to be the same species.
