Muisca Antpitta
Grallaria rufula
Plump bird with long legs and a short tail that ranges in the eastern Andes of Colombia, barely reaching over the border into Venezuela. Plumage is chestnut brown with an orange tinge to the breast and slightly paler belly; sometimes shows a faint mustache streak. Skulks in the understory of high elevation elfin forest and usually stays on the ground, but sometimes comes up to a low perch to sing. Common vocalization is a sweet, rising whistle followed by a lower pitched gargle, and also gives a series of flat whistles. It used to be called Rufous Antpitta.
Black Swan
Cygnus atratus
Unmistakable large black swan with a red bill. When swimming this species is almost entirely black. Wings show extensive white flight feathers when flying. Juveniles are similar but dark-gray. In Australia, compare with Magpie Goose, which has white belly, and white underwing with black tips. Typically found along inland waterways, rivers, sewage ponds, and coastal lagoons and inlets. Sometimes flocks together in enormous numbers on large wetlands.
Spotted Crake
Porzana porzana
Medium-sized crake with dense whitish spotting and speckling on the neck and breast. Also note greenish legs and short yellow bill with a reddish base. Breeds in freshwater marshes and wet meadows with dense vegetation cover, but migrants and wintering birds may also be found in ephemeral wetlands and brackish marshes. Retiring and rarely seen, but sometimes comes out at muddy edges, mainly early and late in the day. Song is a series of repeated “huit, huit, huit” notes.
