Chirping Spider?

Anyone know anything about any spiders making noise? While up in NH my mother and I found a large dark grey spider (we think it may have been something related to a fisher spider.) it looked kind of sick so we poked it on the butt. It did not move, but it let out a LOUD chirp! any ideas?

Stridulation
Several different groups of spiders make sound by rubbing body parts together, technique know as stridulation (that's how crickets chirp). Wolf Spiders are one of the more common of those groups, and some do, indeed, look sort of like Fishing Spiders.

Schizocosa ocreata is a North American species whose use of stridulation in courtship has been studied recently. We don't have it in the Guide, but we have some images of unidentified Schizocosas:


Most of the references about Wolf Spider stridulation I can find on the web have to do with its use in courtship by the male. I assume, though, that it could also be used to startle a predator so the spider could escape.

I have no idea what this stridulation sounds like.

 
Thanks!
If my mother had not heard it also I would have thought I was going nuts!!! I've never heard of a spider making noises before, and this was definately not a noise one would have related to a spider!

Perhaps
I don't know about your specific situation, but according to this site some spiders can make noise.

 
Thank you!
Great site! The noise was more like a squeak or a chirp, not a whistle, but the way they describe how it is made, I can see how it may have produced the noise!
