Survey Calendar

Located below is a calendar outlining the survey schedule for the summer 2021 field season. Due to how the arrival dates and lunar cycles are lined up in 2021, there are two lunar cycles this upcoming year.

 

Southern Maine: If a nightjar is detected along a route in southern Maine during the first lunar cycle (May 19 – June 2), the route will need to be re-run 7 or more days later during the 1st lunar cycle or early during the 2nd lunar cycle (June 17 – June 30) to document the level of confidence that nightjars are breeding along the route.

Northern Maine: If a nightjar is detected along a route in northern Maine during the first lunar cycle (May 25 – June 2), the route will need to be re-run during the 2nd lunar cycle (June 17 – July 1) to document the level of confidence that nightjars are breeding along the route. Sunset surveys do not need to be re-run.

A note on the full moon: Full moon conditions offer the best survey conditions so long as there are acceptable weather conditions. The full moons impacting the 2021 field season are May 26 and June 24th.
