An Egyptian goose (Alopochen aegyptiacus) perching in a tree. Egyptian geese are unusual as geese go in that they sometimes perch, and even nest, in trees. One year, probably back around the year 2000, our resident pair on the large lake nested at the top of the broken trunk of a tree that leaned out over the lake. Normally they nest on the ground among the bushes on the island.
