Another beautiful day for outdoor work. Steve checked woodland boxes, Kristin did the meadow ones, with a big team to help. Stanley left a bag of Burke Rd. bats in my garage to keep cool.

 

 

 

Kristin has done her Working at heights training and with harness and helmet, checked half the boxes. Most of the bats were in the ones Steve checked.

 

 

 

 

 

Tim Bawden of Birdlife Aust. joined us again. 7 boxes had bats, so 18 were empty – lots of ladder-climbing to find just bat droppings or Huntsmen. One of the new boxes, B26, shows signs of being used a lot by the bats. There were three in it this month.

 

 

Soon after 5 we moved to my overcrowded back deck and processing got under way, Evie, Caroline and Helen assessing.We also had a new recruit in Lauren Nankervis.

 

 

Steve’s laptop has a complete history of all banded bats, which Rebecca checked each time a new bat was brought out of its bag, to ensure only real band numbers were recorded, and good decisions about repro con were made.

 

 

There was one Broadnosed male bat, banded in Jan. 2015, recaptured in April, and now a 3rd time.

 

 

Processing, with Steve taking genetic samples for Danielle’s project, was over by 7 p.m., and I went down to release the bats at 8:30. They all flew off quickly.

 

 

There were 47 bats, all Gould’s except the one Broad-nose, 1.6 females per male, the reverse at Burke Rd.
