#'Bat Echolocation Calls
#'
#'Bat echolocation calls were recorded across north and central Mexico from June
#'to November 2012 and from February to May 2013. Live trapped bats were
#'measured and identified to species level using field keys and recorded in
#'flight. Echolocation calls were recorded with a Pettersson 1000x bat detector
#'(Pettersson Elektronik AB, Uppsala, Sweden)  set to record calls manually in
#'realtime, full spectrum at 500 kHz. Each recording consisted of multiple calls
#'from a single individual bat. As many individual calls as possible up to a
#'maximum of 100 calls per species are included. In total the dataset consists
#'of 22 species from five families, 449 individual bats and 1816 individual
#'echolocation call recordings. See source material for species level details.
