Anyway, fastforward to one night last week, when something finally figured out how to unhook the feeder from the carabiner I had it hung from, dropping it on the ground and making for "free for all". Well, I fixed them - yesterday I installed it with a locking carabiner, so they will have to unscrew the "locking" part before they can open the "flap".
So last night as I'm almost drifting off to sleep, I think I'm hearing some unusual background noise that, in my sleepy state, I thought was elsewhere in the house. Then, I come a little more awake, enough to realize it is not background noise, and not in the house. This brings me wide awake. It sounds like an angry animal, or more accurately pair of animals, and it is outside the bedroom... kind of in the direction of the bird feeder. It wasn't a cat fight. I started thinking possum or raccoon (we've seen both in the area). Grabbed a flashlight and shined it out at the tree - the leaves on the branch holding the feeder are SHAKING AND BOUNCING like crazy. And I continued to hear the angry sounds. I call my husband (he was still up), and we go into the living room with our lights and watch for a minute or two more. Then not one but two raccoons come down the trunk out of the tree. One goes over under the bird feeder (reaching up toward it like a little kid trying to get something that's out of reach) and the other "heads for the hills".
I want to go back to having problems with the squirrels, please.
