Definition
-
Agelasticus xanthophthalmus is a species of bird commonly known as the Yellow-eyed Blackbird. It belongs to the family Icteridae and is native to South America, particularly Argentina, Uruguay, and southern Brazil.
The Yellow-eyed Blackbird is a medium-sized bird, measuring around 18 to 20 centimeters in length and weighing approximately 60 grams. It has a predominantly black plumage, except for its distinctive yellow eyes, which give it its name. The male and female individuals exhibit sexual dimorphism, with the males possessing a brighter and glossier black coloration, while the females have a slightly duller appearance.
This species is typically found in wetland habitats, such as marshes, swamps, and reed beds. It is known for its preference for areas with tall grass and thick vegetation, as it uses these habitats for nesting and foraging. The Yellow-eyed Blackbird primarily feeds on invertebrates, seeds, and small fruits.
The breeding season of Agelasticus xanthophthalmus usually occurs between October and March. During this time, the male performs elaborate courtship displays, including singing and aerial maneuvers, to attract a mate. The female constructs a cup-shaped nest from grass and other plant materials, typically hidden among reeds or tall grass. After mating, the female lays a clutch of two to four eggs, which are then incubated by both parents.
Despite being a widespread species, the population of Yellow-eyed Blackbirds has experienced some decline due to habitat loss, pollution, and agriculture expansion. Efforts are being made to protect their wetland habitats and ensure their conservation.
Etymology of AGELASTICUS XANTHOPHTHALMUS
