So last night at 11:50 PM, my sister woke me up telling me that she heard “a chorus of screams.” I told her it was probably a fisher and to go to bed. I played a fisher scream and barred owl shriek to her, and she said none of them matched. She described it as short spurts of screams every 5 seconds, and the scream was about half to three quarters of a second long. They started at a low pitch and worked they’re way up to a high pitch. Any input would be great.
