​Maine Nightjar
Monitoring
Project

The MNMP is focused on the study of nightjars in Maine. Efforts are primarily directed towards two nightjar species: Eastern Whip-poor-will and the Common Nighthawk. Both species have experienced declines over recent decades, prompting the initiation of our research efforts. 

 

"What are Nightjars?" Nightjars are medium-sized, cryptically colored birds of the family Caprimulgidae, or “goatsuckers”. They are generally either nocturnal (active at night) or crepuscular (active at twilight) and nest directly on the ground. While most are difficult to observe directly, many species can be readily detected and identified by sound. 

 

A third nightjar species, the Chuck-will's-widow, has been documented as a vagrant in Maine since the 1970's. This southeastern nightjar species has been increasing its range along the Atlantic coast throughout the last century and was first documented breeding in Maine in 2023.

 

Profiles for each species can be found below. Visit each profile to view photos, recordings, and descriptions of behaviors you may observe during the breeding season.
