Maine Nightjar Monitoring

Want to help us monitor nightjars, owls, and other nocturnal birdlife on moonlit summer nights? The Maine Nightjar Monitoring Project is seeking new volunteers! Maine’s nightjars, the Eastern Whip-poor-will and Common Nighthawk, are experiencing declines throughout their breeding ranges. Anecdotal reports indicate significant declines in Maine in recent decades. You can help us gather the data needed to inform their conservation here in Maine.

Maine Bird Atlas - Volunteers Needed!

The Maine Department of Inland Fisheries and Wildlife is pleased to announce the 2018-2022 Maine Bird Atlas! This project will map the distribution, and often abundance, of bird species in Maine with an initial focus on breeding birds (atlasing of Maine's wintering birds will begin by late 2018). Maine’s first breeding bird atlas spanned 1978-1983, and with a second atlas we can compare these two data sets and determine changes in our breeding birds.
