2023 Survey Dates

The 2023 U.S. Nightjar Network survey dates are here! Per your requests, new windows have been added so please review the changes and contact us with any questions. These dates are specifically chosen to coincide with the nights of brightest moonlight and greatest nightjar calling frequency. These are important dates to use so survey conditions are standardized across all regions of the Nightjar Survey Network. Contact with questions.
