About the Golden-winged Cacique
The Golden-winged Cacique, known scientifically as Cacicus chrysopterus, is a striking member of the Icteridae family. This medium-sized bird is native to South America and is particularly prevalent in countries such as Argentina, Brazil, Paraguay, and Uruguay. It thrives in subtropical and tropical moist lowland forests, showcasing a preference for edges and clearings where it can exploit both arboreal and terrestrial resources.
The Golden-winged Cacique plays a crucial role in its ecosystem, acting as both a seed disperser and an insect predator. Its diet primarily consists of fruits, nectar, and insects, which it finds throughout its habitat. By consuming a variety of fruits, this cacique aids in the dispersal of seeds, thus supporting the regeneration of forested areas. Its insectivorous habits help control pest populations, maintaining ecological balance.
Seasonally, the Golden-winged Cacique exhibits altitudinal migration, moving to lower elevations during the winter months to escape colder temperatures. During breeding season, which occurs in the spring and summer, these birds become more territorial, establishing distinct areas where they construct their nests. The cacique's social nature is evident year-round, as they often form small flocks when foraging, contributing to their visibility and audibility in their native regions.
In addition to their ecological roles, these birds are of cultural significance in many South American communities. They are often featured in local folklore and are appreciated for their vibrant plumage and lively vocalizations. Despite facing habitat loss due to deforestation, the Golden-winged Cacique remains a vital and cherished part of the South American avian landscape.
The Golden-winged Cacique belongs to the family Icteridae, within the order Passeriformes. These birds typically live average 7 years, with a maximum recorded of 11 years..
How to Identify a Golden-winged Cacique
The Golden-winged Cacique is easily identified by its striking coloration. Adults sport a predominantly black plumage with glossy feathers that catch the sunlight. The most distinguishing feature is the bright yellow patch on their wings, which is visible even at a distance. This yellow coloration extends to the rump, providing a stark contrast to the rest of the bird's body.
Males and females are similar in appearance, although males tend to be slightly larger and more vibrant in their yellow pigmentation. Juvenile caciques resemble adults but have duller plumage, with less pronounced wing patches and a brownish tinge to their feathers. This difference becomes less noticeable as they mature and molt into adult plumage.
In flight, the Golden-winged Cacique presents a distinctive silhouette with broad wings and a slightly rounded tail. The contrast of yellow and black is often a key identification marker. When perched, they exhibit a slightly hunched posture with a strong, pointed bill that hints at their omnivorous diet. Observers might confuse them with the Yellow-rumped Cacique, but the Golden-winged Cacique's wing coloration and slightly larger size help distinguish it.

Golden-winged Cacique Habitat and Range
Preferred Habitat
Golden-winged Caciques favor subtropical and tropical moist lowland forests. They are often found at forest edges, in clearings, and near rivers, where their foraging opportunities increase. These birds inhabit elevations up to 1,500 meters but descend to lower altitudes during colder months.
In urban areas, they can sometimes adapt to parks and gardens, making the most of fruiting trees and flowering plants. However, they are more commonly associated with rural and forested regions. Their adaptability to various forest types allows them to exploit different ecological niches, although they show a marked preference for dense canopy coverage.
Seasonal habitat shifts are primarily altitudinal, as they move to more temperate zones during winter. While they are not typically a common sight in deserts or open grasslands, they occasionally venture into these areas when searching for food or during migration.
Geographic Range
The Golden-winged Cacique's range extends across much of South America. It is predominantly found in southeastern Brazil, northeastern Argentina, Paraguay, and Uruguay. These regions provide the subtropical and tropical environments that the species favors.
During the breeding season, these birds are more concentrated in forested areas, particularly in the Atlantic Forest region. This area provides ample resources for nesting and feeding. In the winter, the cacique's range shifts slightly, with individuals moving to lower elevations and sometimes further north to escape the cooler temperatures of the southern regions.
Though not strictly migratory, they do exhibit local movements within their range, often dictated by food availability and climatic conditions. Population density is higher in regions with extensive forest cover, while fragmented habitats tend to support smaller, more isolated groups.

What Does the Golden-winged Cacique Eat?
The diet of the Golden-winged Cacique is varied, comprising primarily fruits, insects, and nectar. They exhibit opportunistic feeding behaviors, making use of whatever resources are seasonally abundant.
During the spring and summer, when fruit is plentiful, caciques focus on consuming a variety of berries and fleshy fruits. Their strong, pointed bills are well-suited for extracting seeds, which they help disperse across their habitat. Insects become a more significant part of their diet in the fall and winter when other food sources are scarce.
Foraging often occurs in the early morning and late afternoon, when they are most active. They use a combination of gleaning and snatching techniques, frequently observed hopping through branches or taking short flights to capture prey. The Golden-winged Cacique's ability to adapt its diet to the changing seasons and availability of resources is a testament to its ecological versatility.
Golden-winged Cacique Behavior and Social Structure
Golden-winged Caciques are social birds that often form small flocks, especially outside the breeding season. Their social structure is relatively fluid, with individuals joining and leaving groups as they forage.
Territorial behavior becomes more pronounced during the breeding season. Males establish territories and defend them vigorously, using vocal displays and physical posturing to deter rivals. Courtship involves elaborate displays, where males showcase their wing and rump patches to attract females.
These caciques are diurnal, active throughout the day with peak activity in the early morning and late afternoon. They communicate through a range of vocalizations, which serve to maintain group cohesion and alert others to potential threats. When faced with predators, they often mob the intruder, using their numbers to drive it away.
Flocking behavior provides safety in numbers and increases foraging efficiency, allowing them to exploit a variety of food sources. Their lively nature makes them a prominent feature in the soundscape of their habitat, with their calls often echoing through the forest.
Golden-winged Cacique Nesting and Reproduction
Golden-winged Caciques construct intricate, pendant nests that hang from the ends of branches. These nests are woven from grasses, vines, and other plant fibers, creating a secure environment for their eggs and chicks.
Preferred nesting sites are often found in tall trees, providing protection from ground-based predators and a clear vantage point for approaching threats. Clutch size typically ranges from two to four eggs, which the female incubates for about 14 to 16 days.
Once hatched, chicks remain in the nest for approximately 25 to 30 days before fledging. During this time, both parents participate in feeding and caring for the young, ensuring a balanced diet of insects and fruits. The Golden-winged Cacique usually raises one brood per year, although in optimal conditions, a second brood may occur.
The communal nature of their nesting sites, often with multiple nests in close proximity, provides additional security through collective vigilance. This community approach to nesting further highlights their social behavior and cooperative breeding strategies.
Golden-winged Cacique Sounds and Vocalizations
The Golden-winged Cacique's vocalizations are a defining characteristic, contributing significantly to their identification. Their primary song is a series of melodious whistles and chatters, characterized by a rhythmic sequence with varied pitch and tempo.
