MassWildlife: Five Years of Bat House Monitoring

Print Story | Email Story
December is a season of gratitude—and this year, we're shining a light on MassWildlife's volunteer bat house monitoring program. Thanks to the dedication of 23 volunteers across Massachusetts, all 34 bat houses at 30 sites were monitored regularly during the summer months in 2025 despite mosquitoes, summer storms, and busy schedules. Over the past five years, a total of 53 volunteers have contributed to the program. Seven volunteers have participated every year since the start of the program, providing consistency and invaluable expertise that guides and strengthen the project.
 
Massachusetts is home to nine bat species. Several, including the little brown bat and northern long-eared bat, have suffered steep population declines due to white-nose syndrome, a fungal disease that has devastated bat colonies across North America. Summer roosts are essential for bat survival because they provide females a safe, warm place to raise their pups.
 
Bats roost in natural areas like tree cavities, and in structures like house attics and barns. Bat houses play an important role in conservation by providing alternative summer roosting habitat when other suitable sites aren't available. Properly designed and placed bat houses can support colonies of dozens to hundreds of bats, giving them a secure location to rest during the day. By relieving pressure on human structures, bat houses also help reduce conflicts between people and bats.
 
Results from bat house monitoring are as follows:
  • Year 1: 16 percent occupied, 26 percent showed potential use
  • Year 2: 7 percent occupied, 10 percent showed potential use
  • Year 3: 10 percent occupied, 23 percent showed potential use
  • Year 4: 6 percent occupied, 15 percent showed potential use
  • Year 5: 15 percent occupied, 9 percent showed potential use
Although bats can take several years to adopt artificial roosts, the signs of activity we see each summer are promising. Bat house occupancy varies, which is expected since bats naturally rotate between multiple roosts. These results show steady signs of bat activity and a strong likelihood that the houses will continue to be used in the future.
 
Volunteer bat house monitoring efforts are helping MassWildlife understand species distribution and abundance in Massachusetts, which bat house designs and placements are most successful, and how bat populations respond to changes in habitat availability. Every observation helps build a clearer picture of bat ecology in our state, informing both research and conservation strategies. Thanks again to all of our volunteers for your dedication to bat conservation.

Letter: When the Justice System Becomes a Tool for Harassment

Letter to the Editor

To the Editor:

I am 74 years old. I spent 45 years in the professional painting trade and have always been known as a dedicated, law-abiding citizen, as well as a passionate self-taught artist and photographer. Yet, I have recently discovered a terrifying flaw in our legal system: it can be easily weaponized by individuals to harass and disrupt the lives of the innocent.

Just over a year ago, what began as a simple, justified complaint about unbearable noise in my apartment — my place of retirement and peace — spiraled into a nightmare. Instead of the system protecting my right to a quiet home, it allowed the upstairs neighbors to fabricate allegations and bring false criminal charges against me.

It is a bitter irony that a senior citizen with a clean record can be railroaded through a court system based on the word of individuals who show a disregard for the law. Even more distressing is seeing a parent stand by and support perjury rather than guiding their family toward integrity.

I am sharing my story because the public needs to know that simply being in the right isn't always enough to protect you. When the court allows itself to be used as a means of retaliation, it ceases to be a system of justice and becomes a system of shame. We must do better to protect our seniors from such blatant legal abuse.

Even though I moved out of that property months ago, on our most recent court date last week, the court again extended a restraining order against me based on completely unjustified complaints by the plaintiff.

We must hold our system accountable to ensure it protects the vulnerable rather than punishing them.

Sincerely,

Luciano Guadagno
Pittsfield, Mass.
