unknown call

["John Hartog" hartogj]

Last weekend while out on a volunteer stream restoration project with
the Oregon Natural Desert Association, I recorded several interesting
call sequences over the night - and here is one of them.   

A creature calls nine times around 3am in this 2:13 min section. 
Earlier around sunset the work crew was mystified by a similar call.
It(or they) also called well into the dawn chorus. (2MB)
