The study also found a great deal of genetic divergence between the species, suggesting that these species are themselves very old. The level of divergence is the highest of any genus of birds, being more typical of the divergence between genera or even families. This raises the possibility that there are several cryptic species to be discovered. For example, the northern potoo was for a long time considered to be the same species as the common potoo, but the two species have now been separated on the basis of their calls. In spite of this there is no morphological way to separate the two species. Their typical foraging technique is to perch on a branch and occasionally fly out in the manner of a flycatcher in order to snatch a passing insect. They occasionally fly to vegetation to glean an insect off it before returning to their perch, but they do not attempt to obtain prey from the ground. Beetles form a large part of their diet, but they also take moths, grasshoppers and termites. One northern potoo was found with a small bird in its stomach as well. Having caught an insect, potoos swallow it whole without beating or crushing it.

SPECIES

Potoos (family Nyctibiidae) are a group of Caprimulgiformes birds related to the nightjars and frogmouths. They are sometimes called poor-me-ones, after their haunting calls. There are seven species in one genus, Nyctibius, in tropical Central and South America.Acomplete skeleton of the genus Paraprefica has been found in Messel, Germany. It had skull and leg features similar to those of modern potoos, suggesting that it may be an early close relative of the modern potoos. Because the only fossils other than these ancient ones that have been found are recent ones of extinct species, it is unknown if the family once had a global distribution which has contracted, or if the distribution of the family was originally restricted to the Old World and has shifted to the New World.

Potoos (pronounced POE-toos) are members of the bird family Nyctibiidae, which contains two genera, Nyctibius and Phyllaemulor. There are seven different species of potoo, which are found in Mexico, Central and South America, and the Caribbean. They're cousins of the nightjars (the family that includes nighthawks and whip-poor-wills), but despite their big eyes and nocturnal habits, they're not closely related to owls.
