Rufous Potoo

The rufous potoo is 21 to 25 cm (8.3 to 9.8 in) long and weighs 46 to 58 g (1.6 to 2.0 oz). The rufous potoo is the smallest member of its family, and the most unusually colored. It is overall a deep orange-red with large white spots; the color is paler on the throat. The spots on the upper belly have a thin black border and the tail has darker bars. It has long bristles in the loral region. It resembles a dead leaf, an impression heightened by its vertical posture on a roost, where it gently sways. Voice: The rufous potoo's song is "a soft, rapidly descending series of roughly 10–15 notes: “bu-bu-bu-bu-bu-bu..." or "whooo, tooo, tooo, tooo, tooo, tooo, tooo, tooo, tooo, tooo, tooo, toot" that resembles the songs of some small owls. It mostly, and perhaps exclusively, sings during a few days around the full moon. It also makes "wup" or "urt" calls.
