The Grey-headed Chachalaca (Ortalis cinereiceps) occurs from eastern Honduras to northwestern Colombia. Although related to chicken, the large birds are arboreal, climbing in trees and walking along branches in search for fruits and berries. Consequently, they are mostly seen in woodlands, secondary forests, and shrubby areas. Chachalacas are quite social and live in groups of six to twelve individuals. I have seen them in Central Panama in March 2014. Unfortunately, just after I took the photograph above, the bird jumped into cover behind leaves and twigs.
