Mystery Solved

It looks like we have ourselves an American Kestrel, a little falcon.  This is good news for us.  They like to eat mice.  We have noticed that a few mice have taken up residence in our backyard by our wood pile, ever since construction began behind our house.  

So if we can put up with a little poop, our little friend should be able to keep our mice problem under control... Yeah!

Thanks dad!
