Class B First-hand BFRO #15835

Possible Vocalizations heard in Southern Alberta

BFRO YEAR: 1991 or 92 evening but not yet dark Lethbridge, Alberta 1 witness

Account

One evening in summer, the witness sat on the back deck of a home on the coulee banks and heard loud, garbled, female-like vocalizations from below the embankment toward the river. The sounds first suggested someone in trouble, then a mountain lion, but later the witness felt they closely matched a chatter recording. No creature was seen.
