Aldergrove can help regional program document bats as they come out of hibernation

International Bat Appreciation Day occurs annually on Saturday, April 17

Spring is the time when bats are emerging from hibernation and moving to their summer habitat.

Danielle Dagenais, regional bat coordinator, said with the beautiful weather expected on Saturday – International Bat Appreciation Day – people are sure to see bats in the area.

“Local parks and areas with fresh water provided great habitat to watch bats,” Dagenais said. “The BC Community Bat Program is very interested in hearing from homeowners and businesses in the area with the date bats return to roosts.”

In mid-April, bats in the Greater Vancouver Region are migrating from their winter hibernaculum [place where animals seek shelter to hibernate] to their summer habitat.

Dagenais noted that during this time, bats are often reported above people’s doorways.

“Please allow the bat to stay and rest. They need to replenish their fat reserves after hibernating, and females are preparing for pregnancy,” she explained. “They will feed on insects for a few nights and then continue their journey to their summer habitat. There are no concerns if you allow the bat to stay and do not disturb it.”

People are asked to report bat sightings and the date bats return to their roost to Dagenais at 1-855-922-2287 ext. 11.

Other ways to help bats survive the spring is to work with local or regional groups to conserve bat habitats (such as old trees and buildings, and water bodies) on properties and in the community.

People can also participate in monitoring and habitat enhancement programs to help bats. That can include installing bat boxes
