About These Birds
Black-chested Jay
The Black-chested Jay is a medium-sized, boldly patterned jay of humid lowland forests in Central America and northwestern South America, with a blue body, black head and breast patch, and a white forehead patch. It ranges from Honduras south to Ecuador and Venezuela, inhabiting forest edges, secondary growth, and sometimes gardens. It feeds on fruits, large insects, and occasionally small vertebrates.
Eurasian Magpie
The Eurasian magpie is one of the most intelligent animals on Earth and the first non-mammal demonstrated to recognize itself in a mirror. These bold corvids build elaborate domed nests of sticks and have a well-known attraction to shiny objects, though this reputation may be exaggerated.
