About These Birds
Alagoas Antwren
The Alagoas Antwren is a critically endangered antbird of northeastern Brazil, weighing about 10 g with a wingspan near 10 cm. It is restricted to very small forest fragments in Alagoas state and faces severe extinction pressure from ongoing deforestation and habitat fragmentation.
Black-headed Antbird
The Black-headed Antbird is a compact antbird; males have a bold black head contrasting with gray-blue underparts and brown upperparts, while females are brown with a rufous head. It inhabits dense, humid forests and river-edge vegetation in Amazonia, particularly in Brazil, Colombia, and Peru. It often accompanies army ant swarms, feeding on the small invertebrates they flush from the leaf litter.
