Patterns in the Calling Activity of the Pauraque Night jar, Nyctidromus albicollis

Victor C. Quesnel


The Pauraque, Nyctidromus albicollis, is a very vocal night jar with a varied repertory of sounds. I have heard five distinctly different calls that are common and two others that are not common. As is to be expected, the sounds are used in different situations. The first call seems to be a declaration of territorial ownership, but additional uses are discussed later. The second call seems to be used for communication between members of a pair or family group. The third call seems to be an alarm. The fourth call accompanies a ritualized display that I interpret as courtship. The fifth call I have heard only mixed with other calls and its use is not at all clear. This paper mainly concerns the first call.
