Bats at Wilson Reserve and Burke Rd. Billabong, 23 September 2017

September usually brings a flock of bats back into the boxes, so we had a good turnout. Shaun Coutts and daughter Essie, who helped scribe for Dani.

 

 

 

And one of Casey’s students at Uni Melb: May Lingzi with her friend Jensen, here with Stanley

 

 

 

Stanley had left one bat from Burke Rd in my garage, and there were another 22 from Wilson Reserve.

 

 

 

Back at my house, Olwyn did some of the assessing.

 

 

 

And Andrej Hohmann, back from 4 months in California studying Spotted Owls in a very long-term project.

 

 

 

May and Jensen were interested observers, learning about what happens with field bat research, and scribing.

 

 

Steve had several new Large Forest bats to band, and a couple of new bats to microchip, with the new supplies paid for by a Bendigo Bank grant of $1,700, which is most helpful for our project. I went down to the boxes to release the bats at 7 p.m., with a huge chorus of Pobblebonk frogs all around after several rainy days.

We collected 23 bats altogether, of three species, with 6 escapees, that flew out when the ladder bumped the box and almost 3 females for each male.

 

8910Old female, White spot, 4408006

After a month’s absence, she was back again, the only one of her generation to reappear, feisty as ever. She’s now been captured 64 times, her weight about normal for Sept. We won’t be able to tell until next month whether she’s pregnant and still interested in reproducing.

 

Large Forest Bats

The 6 females this month take the total of this species to 18, 9 of them last Sept. We get males in Apr-May, and females in Sept. One female, 16964, was among those found a year ago, and is the only one ever to appear twice.

Sugar Gliders

Steve did the woodland boxes, and peeking into glider box 3 (same tree as bat box 16), found a glider staring up at him. He’s sure there were two others further down in the box. It’s the first time this box has been occupied.
