The Green-winged Saltator (*Saltator similis*) is a strikingly handsome songbird native to the forests and woodlands of eastern South America, from Brazil to Argentina. Its general appearance is sleek and elegant, featuring a soft gray back and head that contrasts vividly with a bright white throat and a bold, white eyebrow stripe. The species’ most distinctive feature is its namesake: the brilliant, olive-green edging on its flight feathers and tail, which flashes beautifully in flight. A special characteristic is its powerful, thick, finch-like bill, which it uses to crush seeds and fruits with ease, though it also actively hunts for insects. Renowned for its clear, melodious song—a series of rich, fluty whistles often delivered from a high perch—this saltator is a favorite among birdwatchers for its vibrant plumage and captivating vocalizations.

Faits amusants

Despite its name, the Green-winged Saltator is not a true saltator—it belongs to the tanager family, Thraupidae, not the cardinal family, making it a taxonomic trickster. It has a quirky habit of “anting,” where it rubs ants on its feathers to use the formic acid as a natural insecticide and feather conditioner. Males perform a curious, bouncy courtship display, hopping sideways along branches while singing a rapid, chattering song that sounds like a tiny machine gun. Its thick, finch-like beak is perfectly adapted for crushing hard seeds and fruits, but it also occasionally snatches small snails for calcium, showing a surprisingly omnivorous streak.

Habitats et répartition

The Green-winged Saltator primarily inhabits forest edges, secondary growth, and dense shrubby areas within the Atlantic Forest biome. It is also found in plantations, gardens, and wooded savannas, often near water sources. This species is endemic to South America, with a geographical range that extends from eastern Brazil through Paraguay, northeastern Argentina, and into Uruguay. It occurs from lowland areas up to approximately 2,200 meters in elevation, though it is most common in the lowlands and foothills.

Comportements & Reproduction

The Green-winged Saltator is generally observed in monogamous pairs during the breeding season, which typically coincides with the austral spring and summer. These pairs form strong bonds and are often seen foraging together or engaging in duet-like vocalizations that reinforce their territory. The social structure outside of breeding is less rigid, with individuals sometimes joining small, loose flocks, particularly during non-breeding periods or when food is abundant. Mating involves a courtship display where the male presents food to the female, a behavior that strengthens the pair bond. The female builds a cup-shaped nest in dense vegetation, where she lays two to three pale blue eggs with dark speckles. A unique reproductive strategy is their reliance on cooperative feeding; both parents share incubation duties and actively feed the chicks, which fledge after about two weeks. They do not exhibit brood parasitism or communal nesting, but their biparental care is thorough, ensuring high fledgling success in their subtropical forest habitats.

Alimentation

The Green-winged Saltator is primarily a frugivore and granivore, with its diet consisting heavily of a wide variety of ripe fruits, berries, and seeds. It is particularly fond of the fruits of the *Cecropia* tree and various melastomes, and it will readily visit bird feeders for offerings like papaya, banana, and sunflower seeds. An interesting fact about its feeding behavior is that it often supplements its plant-based diet with small insects, such as caterpillars and beetles, especially during the breeding season to provide extra protein for its chicks. Furthermore, this species plays a crucial role in seed dispersal, as it swallows fruits whole and passes the seeds intact through its digestive system.

Couleurs

The Green-winged Saltator has olive-green upperparts and wings, with a pale gray breast and whitish throat bordered by a thin white eyebrow stripe and a black malar line. Its underparts are buffy-gray, and the tail is dark with greenish edges. It lacks distinct camouflage adaptations, instead relying on its muted green and gray tones to blend into forest foliage.
