The Thick-billed Saltator (Saltator maxillosus) is a species of saltator in the Cardinalidae family. It is found in highland Atlantic Forest in southeastern Brazil, far northeastern Argentina (only Misiones Province), and perhaps far eastern Paraguay. Unlike most other saltators, it is sexually dichromatic: Females resemble a Green-winged Saltator, but with a thicker bill, greener face and buff throat. The male Thick-billed Saltator is unique with its long white eyebrow, grey back, and black and orange beak (amount of orange varies).
