Bats are providing invaluable services to our ecosystem and our economy. What are you doing to help bats in return?

All bats in Canada are insectivores. Every night in spring, summer, and fall they eat large amounts of insects that are agricultural pests, thus acting as a natural pest control. This saves Canada a lot of money and gives us apples, grapes, and other fruits, vegetables and nuts at an affordable price. More bats means fewer insects and fewer pesticides on our crops.
Unfortunately, the fungal disease white-nose syndrome has been responsible for the death of millions of North American bats. We are leading a coordinated response to fight this disease and help bats survive. For more information on what we are doing, see

Mexican free-tailed bats roost in colonies of millions. Depending on the time of year, their diet consists of 30 to 90% moths, including moth species that consume corn. The estimated value of bats to the corn industry is $1 billion annually worldwide!

Bats are among the most diverse group of mammals and represent about 20% of all mammalian species. Worldwide more than 1300 different bat species have been described, from the smallest (the bumblebee bat: 2 grams) to the largest (the golden-crowned flying fox: 1.2 kg with a wingspan of 1.7 meters).
Bats live on all continents, except Antarctica, and fill many niches in the ecosystems they live in. There are bats that feed on insects, fruit, nectar, blood, frogs, fish, other bats, and more. Many bats can use echolocation to navigate in the dark and have faces that are adapted to accommodate this. Others have faces that help guide fruit juice to their mouth.
Today we honour the beauty of diversity with this tribute to the many faces of bats!

Bats are still highly misunderstood animals. Especially on a day like today people think about bats as scary vampires. While vampire bats do exist, they do not live in Canada and generally only take a little bit of blood from live-stock and wild animals (they don’t kill these animals). Did you know that vampire bats feed each other to make sure the whole colony remains healthy? There is much to be learned from their kindness. Here are some more myths on bats that we want to see busted.
Happy Halloween and happy last day of Bat Week. Cheers to the bats.
