This observation documents a curious moose that is damaging the recorders at my study site.

1- Destroyed microphone. The moose left its loose guard hairs on this and other microphones throughout the site.
2- Another microphone with windscreen eaten and loose guard hairs left on it.
3- Ample moose scat throughout site.
4- Recording of a moose walking up to and mouthing the microphone of an autonomous recorder, the same microphone pictured in (1). Walking sounds start to be more audible at about 25s in. Breathing and chomping audible at about 35s in.

Several moose were seen at my site, on separate days, since I posted this observation. No other large mammals (e.g. elk, deer, bear) have been observed.
