We have also worked with CSIRO in Atherton to trial both satellite and radiotracking collars on Spectacled flying foxes. There have been similar issues to those with the Little Red trials, with collars rubbing, and some intolerance of them. The CSIRO trials were all done on flying foxes that could fly, but were choosing to live at the bat hospital outside the cage.
Photo left: This bat wore away fur by constantly licking, as did one bat in the Little Red study. One bat in both trials showed this intolerance to the collar, both beginning the licking behaviour in the first few hours. To exclude these bats from use in research, consideration could be given to collared bats being held for at least 24 hours before release. Suitable housing would need to be provided and their stress levels monitored.
Photo right: In both studies, some collars swung around to the front, but in all cases the bats were able to swing them back again.
