How to recognise an Audubon's oriole?

General appearance

The Audubon’s oriole is a medium-sized bird approximately the size of a Robin or 9 1/2 inches (24 cm) in length. Its most distinct feature is the stark contrast of colors with a solid black hood, black tail and mostly black wings against a yellow-green back. The bird's wing and tail shapes are rounded with a wedge-like appearance

Male vs female

Male and female Audubon’s orioles share similar coloration, but the female is slightly duller than the male. Notwithstanding, they both bear the distinctive yellow-green back strongly contrasting with their black regions.

Juvenile

Young Audubon’s orioles present a much duller color scheme than adults, mainly lacking the solid black found on mature birds. Over time, their plumage develops to resemble that of adults, thus indicating sexual maturity.

Icterus spurius

How to recognise an orchard oriole?

General appearance

The orchard oriole is a small bird about the size of a robin. It is smaller than the Baltimore Oriole, with a unique rounded wing shape and rounded, square-tipped tail shape. The bird's size is characterized as 7, measured in 18cm. The oriole’s colour palette consists of black, green, orange, red, white, and yellow.

Male vs female

There are noticeable differences between males and females. The adult male orchard oriole is unmistakable with its striking black and chestnut coloration. On the other hand, the female is smaller and flaunts an all yellow-green appearance. They lack the orange tone seen in the female Baltimore and Bullock's Orioles and have a shorter bill compared to Hooded Oriole.

Juvenile

One-year-old males, or juveniles, resemble the females but have a distinguishing black throat. This characteristic is one of the earliest signs to distinguish between young males and females.

Size

5.9 - 7.1 in/0.6 - 0.9 oz

Habitat

Primary habitat

The orchard oriole typically resides in semi-open habitats with deciduous trees and open spaces including riverside trees, orchards, suburbs, forest edges, and prairie groves. It avoids unbroken forests.

Additional range

In the winter, the orchard oriole migrates to tropical lowlands, favoring brushy areas and woodland edges.

What do orchard orioles like to eat?

Natural diet

The orchard oriole's diet primarily consists of insects, with a strong preference for caterpillars, beetles, and grasshoppers during the summer. Their diet also includes spiders and varies with the seasons. In fall and winter, they tend to consume more berries, while nectar and parts of flowers are common components of their diet year-round.

Bird feeders

At bird feeders, orchard orioles are known to be attracted by offerings such as fruit, nectar, and sometimes jelly due to their natural preference for sugary foods and fruits. However, they may be less frequent at feeders compared to other oriole species.

What does an orchard oriole sound like?

The orchard oriole's vocalization resembles a rapid musical warble, akin to the Purple Finch, albeit less rich in quality. Its call pattern follows a complex, undulating, and descending sequence. Typified by sounds resembling a chirp or chip, the orchard oriole's songs also tend to flute-like and whistle tones, giving its vocal repertoire a distinctive sound.

How to tell the Audubon’s Oriole from the Orchard Oriole

Visual differences

The Audubon's Oriole, approximately 9.5 inches long, is larger than the 7-inch Orchard Oriole. Audubon's features a distinctive black hood and tail with a yellow-green back, while the adult male Orchard sports a striking black and chestnut body, and females exhibit an all-yellow-green plumage. The juvenile male Orchard has a black throat. Audubon's beak is more robust compared to the Orchard's shorter bill. Both birds show rounded wings, but the Orchard has a square-tipped tail, contrasting with Audubon's wedge-like tail.

Key differences and behavior

Audubon's and Orchard Orioles show distinct behavioral differences vital for field identification. Audubon's Oriole, larger and shyer, often visits feeders and is notable for its duets, maintaining year-round pairs in wooded areas of Texas and Mexico. In contrast, the smaller, migratory Orchard Oriole prefers semi-open habitats and travels at night. Unlike Audubon's, it is not strongly territorial, often nesting in proximity. Both species build hanging pouch nests, but Orchard Orioles can share trees with other bird species. Audubon's primarily consumes insects and berries, even at feeders, while Orchard Orioles favor caterpillars and nectar, infrequently appearing at feeders. Bronzed cowbirds often parasitize Audubon's nests, a concern less associated with Orchard Orioles.
