In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
The level of divergence is the highest of any genus of birds, being more typical of the divergence between genera or even families. 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 .
The hunt ends as dusk becomes night, and resumes when night becomes dawn. [13] Nighttime feeding (in complete darkness) is rare, [ 4 ] even on evenings with a full moon.

Developing conservation strategies for some species presents a particular challenge in that scientists do not have enough data to determine whether or not a species is endangered due to the difficulty in locating, identifying, and/or categorizing their limited number (e.g. 10,000) known to exist, a good example being the Vaurie's nightjar in ...
Breeding has been recorded as typically February to August, but depending on the portion of this bird's range breeding birds can be met with almost year-round. [11] The nest is a slight depression on a thick tree branch, [ 12 ] at least 10 m (33 ft) above ground, with a single white (slightly spotted) egg measuring about 5.2 cm × 3.8 cm (2.0 ...
