The Western Great Lakes Bird and Bat Observatory will undertake several new efforts with a group of partners this year, focused on Aerial Insectivores:
- New monitoring and research project in Milwaukee: If you would like to participate in new citizen-assisted monitoring for Chimney Swifts and Common Nighthawks this year, please contact >
- Wisconsin Bird Conservation Initiative Annual Meeting, devoted to Aerial Insectivores, is scheduled for September 7 and 8, 2018. Location, agenda, and program are currently being determined. Please check back here for news and updates.

The Decline of Aerial Insectivores
There is growing concern about the apparent population decline of many “aerial insectivores” – those species that feed on their insect prey in flight. These species belong to a number of avian orders and families, and include swallows and martins, chimney swifts, some forest flycatchers, plus nightjars such as whip-poor-wills and nighthawks.
The WGLBBO is involved in several initiatives aimed at improving monitoring of these birds, and at research into their populations declines. Check back at this page in the coming year to learn more.
