Nightjar Monitoring

 
If you've been following the nightjar monitoring initiative, you know that Michael Wilson (Center for Conservation Biology, College of William and Mary) spearheaded this national effort.  Dave Krueper has been working through the WWG to implement surveys in the west.  Implementation is improving in western states.  It is time to take this to the next level in the west. 
 
See ppt from the Spring 2012 meeting in Reno, attached below.  Help us improve coverage of this survey.   
 
Given the higher detectability of nightjars when the moon is half or more full, and that western nightjars begin calling 1/2 hour BEFORE sunset and drop-off within 2 hours of sunset, the timing of your surveys is somewhat constrained. 
 
This year, 2012, the window of opportunity for evening surveys is from May 28 to June 4.  (The moon at sunset is 1/2-full and waxing until June 4.  After that the moon is waning and more than 1/2-full until June 11, but of course rising 1 hour more after sunset with each day past June 4; the late hour of moon rise is the problem past full moon.)  The other summer window is between June 26 and July 3.
