I am copying this with permission from a post a friend of mine posted on the osprey message board. Someone had mentioned that when she tuned in to the cam at night, she heard a call in the distance that she couldn't identify. Here's the post that followed. It's very cool, if your computer allows you to hear it:
"I've been thinking about your question about those screeching sounds that you heard through the cam mic, at night, last spring...and I'm thinking that you might be referring to the weird call of the Eastern Spadefoot Toad. I did hear it a number of nights and a few days, after heavy rains. They have a bizarre life cycle...they live underground, sometimes for years and then burst up in to the temporary ponds that form after really heavy spring rains. For the few days that the water stands they go wild mating and calling with this very loud, raspy, screechy sound (one description I read said that they sound like a young crow). When the pond dries up they disappear again and may not be seen until the next year or even longer. This year we had an incredibly rainy winter followed by a very wet spring and they came out in record numbers. The noise was so loud that we had to run fans to drown them at at night.
If you go to this site you will see a picture of them:
