Disease affecting bats poses threat to ecosystem, economy

Several species of bats that call Connecticut home have been devastated by white-nose syndrome, so much so that in 2015 three species were listed as endangered on Connecticut’s List of Endangered, Threatened, and Special Concern Species. 
These species are the little brown bat (pictured), northern long-eared bat (also federally threatened), and the tri-colored bat. 
The eastern small-footed bat was also up-listed from special concern to endangered. 
Although the Indiana bat also suffers from WNS, it was listed in 1967 as federally endangered for reasons unrelated to WNS.

As Halloween approaches, images of bats are everywhere -from holiday decorations to super hero costumes and haunted house tours. 
Unfortunately, in recent years, bats have received far more tricks than treats.
In less than 10 years, the disease known as white-nose syndrome has killed millions of bats throughout the Northeast and beyond, having spread to 29 states and five Canadian provinces. 

The threat posed to our ecosystem and our economy, is no Halloween prank, it is one of the most serious conservation challenges we face. 
  • Bats are the single largest predator of night-flying insects. A single colony of big brown bats can eat roughly 1.3 million insects every year—nearly 9,000 insects per bat. 
  • The value of this insect control to agriculture in the U.S. averages $22.9 billion a year. 
  • This doesn’t include the ecosystem benefits provided by keeping insects populations in check which has ripple effects in many areas such as the forest products industry. In some parts of the country, bats also play a key role in pollination.
The species affected by WNS are known as “cave bats.” In Connecticut, they include the little brown, northern long-eared, tri-colored, big brown, eastern small-footed, and Indiana bats. All of these species except the big brown bat are now listed as endangered under the Connecticut Endangered Species Act. 

In 2015, as a direct consequence of WNS, the U.S. Fish and Wildlife Service listed the northern long-eared bat as a threatened species under the federal Endangered Species Act. 
This species, once common in Connecticut and the Northeast, is now considered to be at risk of becoming endangered in the foreseeable future. 
Meanwhile, biologists and researchers in the United States and Canada are racing to determine whether there are safe and effective ways to treat or control the fungus that causes WNS. 
Many of these efforts have been supported by the State Wildlife Grant program, a critical source of funding for addressing urgent wildlife disease issues. 

Since 2007, the DEEP has been an active participant in WNS response. Biologists continue to monitor for signs of WNS in bats and to document mortality, survivorship, and reproductive success.

“Halloween is good time to dispel myths about bats,” said Jenny Dickson, a Supervising Biologist for the Department of Energy and Environmental Protection Wildlife Division. “Rather than harbingers of doom, bats are a key part of healthy ecosystems and provide tremendous economic benefit to agriculture and forestry through their insect control abilities.”

Here are a few interesting facts about bats:

  • Bats are not flying mice. They are the only mammal capable of true flight and are more closely related to primates (and people) than to rodents.
  • Bats do not get caught in people’s hair. They are adept fliers and rely on sensitive sonar (echolocation) to navigate night skies. Bats that swoop near people are after insects like mosquitoes and moths.
  • Bats are not blind. They have good eyesight, but rely on echolocation to navigate in darkness.
  • Bats are not filthy or covered with parasites. Healthy wings are essential for flight, so bats take great care in grooming themselves.
  • Three species of bats are known as vampire bats. They are found only in Latin America and are parasites of birds and cattle.
  • Worldwide there are more than 1,300 species of bats; Connecticut has nine native bat species.
“Learning more about bats and the important role they play in healthy ecosystems would be a great Halloween ‘treat’ for this troubled and misunderstood group of animals,” Dickson said. 
“Knowing why bats matter is an important first step in efforts to address this unprecedented mortality caused by white-nose syndrome.”
Want to learn more about bats? Check out DEEP’s Connecticut Fish and Wildlife Facebook page (www.facebook.com/CTFishandWildlife) for interesting facts, photos, and videos about bats. You can also make a difference by celebrating Bat Week (Oct. 24-31; www.batweek.org) and helping spread the word about the importance of bats.
As cooler weather approaches and bats settle down to hibernate, the DEEP encourages Connecticut residents to help in monitoring WNS by reporting bats observed outdoors during winter. 
While the characteristic white fungal growth may not be readily visible on a bat’s nose, bats observed outside between mid-November and March are a sign that WNS may be at work. 

Details about what you observed, including the date, location, and digital photos if possible, may be submitted to the DEEP Wildlife Division at deep.batprogram@ct.gov or by calling the Wildlife Division, 860-424-3011.
