Hawai'i, and archiving bat calls

[Lauren . Golten <>]

grateful for any suggestions:
 
 1. I am headed to Hawai'i (the Big Island) next week. I am interested in
 recording hoary bats, if I can find them. Does anyone know good spot(s) on
 that Island to look/listen for hoaries?  and/or any other information about
 their activity this time of year?
 
 2. I am beginning to research the procedure for archiving bat calls, in order
 to preserve and curate calls at the University of Colorado's Natural History
 Museum. I would appreciate any information out there on format/procedure for
 archiving sound data.
 
 Thank you very much for any tips you can provide. Happy solstice and holidays,
