Verbreitung und Lebensraum

The highland guan is found on either side of the mountain ranges in Central America. In Mexico it is uncommon, but it is present in moderate numbers in the El Triunfo Biosphere Reserve. It is also common in some localities in Guatemala, but rather rarer in Honduras, north-central Nicaragua and El Salvador, and it may be extinct in El Salvador. Its habitat is humid broad-leaved mountain forests, mainly cloud forests and pine-oak forests, but it has also been observed in secondary forests and plantations. The bird forages for fruit, in the trees and on the leaf litter.
