A wet month but a dry day for us, bringing a mix of new recruits and regulars to help gather bats.

 

 

 

Ashley Mooney brought along two friends, Adam and Sharif Lebban

 

 

 

 

 

Melissa did all the ladder-climbing but there were bats in only one box, B11, so a rather small catch of only 3 bats.

While Stanley, Helen and Melissa went off to Burke Rd to extract bats from two tubes, Danielle did the 3 little bats from Wilson Reserve, with recruit Evie Clarke scribing.

 

 

 

When she left, my grandson, Finley took over.

 

 

Melissa found 6 bats in the tubes so there was a little more work to be done. One was a PIT-tagged Gould’s male, 735B6D6, micro-chipped in January and now captured 5 times. In January he was in a big group of 35 Gould’s, 7 elder Females, 12 young females and 16 young males. The elders were White-spot, two 4-year-olds, two 3-year-olds and two 2-year olds. In Feb. he was in B19 with 3 elder females and 10 young Gould’s. By March he was independent and roosted with 9 other young Gould’s, mostly other males. In May he was in B2 with 9 young Gould’s. This month he was just with White-spot, who may be his mother, or grandmother, or great-grand-mother. So he has moved from dependence to independence.

The solitary Broadnose, 96518, has now been captured 5 times as well, first in Jan 2015 in B4, with two other Broadnosed bats and 8 Gould’s. Then again in May 2015 with 23 Gould’s. In Feb this year he was in B19 with 735B6D6 (maybe they like each other) and 12 other Gould’s. In April he was in B02 with 9 Gould’s. And this month with White-spot and 735B6D6 again, in B11. So he has not been seen from July to December, but only visits from summer to early winter. So our boxes are not quite “home”, but he commutes between them and other unknown roosts.
