How often do you see two species of Potoo in two days?!
This bird was roosting in a tree along the road between the towns of Pilcopata and Atalaya, well into the foothills.

There was some debate on our boat about whether this was a Nazca or a Masked Booby
Birds (class Aves or clade Avialae) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates. Aves ranks as the tetrapod class with the most living species, approximately ten thousand. Extant birds belong to the subclass Neornithes, living worldwide and ranging in size from the 5 cm (2 in) Bee Hummingbird to the 2.75 m (9 ft) Ostrich.
