Unicolored Blackbird (Agelasticus cyanopus) - 16-21Aug2022

This blackbird of South American marshes and wetlands mostly inhabits the southern parts of the Amazon basin and Pantanal which is where I saw these.  However, they also have a population in the northeast of South America.  They look a lot like Chopi Blackbirds but don't share the same habitats and have different vocalizations.  Also, more importantly they are sexually dimorphic and the females look nothing like Chopi Blackbirds. An assortment of males and females are below.
