Introducing the Streak-Backed Oriole: A Fascinating Avian Species with a Stunning Combination of Gold and Black Plumage. These Birds Stand Out for their Beauty and Rarity in the United States.
The icterid family includes a medium-sized bird called Icterus pustulatus, also known as the streak-backed oriole. This bird measures approximately 7.87 inches (200 mm) in length, including its tail, and has a wingspan of 3.54 to 4.65 inches (90 to 118 mm), weighing around 2.47 to 3.00 ounces (70 to 85 grammes). Generally, males are larger than females. The subspecies of “New World Blackbirds: The Icterids” can be divided into three groups with distinct characteristics. The males living in the northern range have bright colors, while the females are usually plain.
As we move towards the southern regions, the female birds appear more vibrant and colorful, resembling the male birds found in the southernmost area they inhabit. Interestingly, females with brighter plumages are more actively involved in protecting their territories compared to their duller counterparts in the north. Although this bird is occasionally seen in the United States, it is primarily found in Central America and Mexico.
Streak-backed orioles typically inhabit open forests and semi-arid shrublands. They tend to prefer areas with prickly Mimosa plants in the understory, but will also choose regions with other prickly shrub species if Mimosa is absent. These birds primarily feed on insects and spiders but also consume fruits, berries, seeds, and nectar.
During the mating season, streak-backed orioles practice seasonal monogamy by remaining with one partner. They reproduce once a year, with nesting activity occurring mostly between mid-spring and late-summer. Nest building is solely done by the female using plant fibers, forming a large hanging basket that measures around 28 inches or 70 centimeters in length. The nests are attached to branch tops. A typical clutch consists of three to four eggs, with an incubation period of 12 to 14 days. Before leaving the nest, the young remain there for almost two weeks and are cared for by both parents. There may be slight variations in these behaviors depending on the habitat.
The number of Streak-backed Orioles is believed to be consistent, as per the IUCN’s classification of them as a species that faces minimal risk.
