Endangered long-tailed bats spotted

Endangered long-tailed bats have been sighted feeding by a street lamp in a residential area of Te Anau, the Department of Conservation says.

Doc hoped to catch some of the bats and attach transmitters so they could be tracked back to their roosting site, biodiversity manager Hannah Edmonds said.

"We suspect these bats are roosting in the Kepler Mountains.

"We would like to confirm this."

The monitoring work would be funded through the Real Journeys Pekapeka/Bat sponsorship and carried out during the next few weeks while it was warm and the juveniles were flying around.

Once rangers located the roost, which could house up to 100 bats, predator protection could be put in place.

In the past, it was thought rats had killed an entire family of bats, she said.

The recent sightings could be the result of the Kepler Challenge Bird Song Project which established a trap line around the length of the track to protect native birds from predation.
