What is "fire-eye"

The fire-eyes, Pyriglena, are a genus of birds in the antbird family Thamnophilidae.The genus contains three species, all found in South America. The fire-eyes are 16–18 cm in length, weigh 25-36 g and have characteristic red eyes that give them their name. They have sexually dimorphic plumage, with the females possessing brown to buff coloured bodies with black tails, and the males being black with small patches of white on the back or wings. The fire-eyes eat a variety of insects, and will regularly follow army ants in order to catch prey flushed by them. Two of the fire-eyes are widespread and safe, but one species, the fringe-backed fire-eye, is threatened with extinction.
