Nocturnal Surveys

If you are a principal atlaser or otherwise plan to spend significant time atlasing, you’ll need to come up with a plan for surveying for crepuscular and nocturnal species. These Nocturnal Survey Guidelines provide information and tips to help you successfully search for owls, marsh birds, and nightjars for the PA Bird Atlas. The following playback sound files can be downloaded and used in conjunction with the Nocturnal Survey Guidelines if you opt to use playback while atlasing.

Playback has the potential to negatively impact birds and should be used sparingly and thoughtfully. Do not use playback at locations where target birds have already been reported.
