On any given night between May 1 and May 15, we could experience a Big Night, and you can join us!

Maine Big Night (MBN) is a nonprofit community science project established to confront the issue of amphibians becoming roadkill en masse. Amphibians, already facing stronger threats than many other groups of wildlife, can see localized declines due to roadkill, and are especially vulnerable during their punctual annual migrations. MBN organizes volunteers to assist these animals across the road while collecting valuable data to protect them for decades to come.

Be a part of the amphibian action by volunteering with certified Big Night monitor, Anneliese Pugh, in counting and assisting amphibians as they cross Egypt Road in Jefferson. Monitoring will happen when the temperature is predicted to be 45°F or higher with rain, especially heavy rain starting a bit before monitoring. This means we will not know very far in advance when each monitoring evening will be, so if you are interested in joining, please sign up below to be alerted 24 hrs in advance of an upcoming Big Night.  

All ages are invited to participate as long as all can obey traffic rules and verbal directions. Participants need to visit the Maine Big Night website to sign the waiver, but please note you do not need to be certified as we will be working with a certified leader. Monitors must wear a reflective vest and carry a flashlight. 

While this is a free event, we appreciate your sign-up which is essential for our planning.

If you have signed up in a previous month in 2026, you do not need to sign-up again.
