I love birds and bird-watching. I have several feeders that I keep stocked up with seeds, dried corn and suet. Yesterday, I checked out a bird guide that has an accompanying CD of birdsongs. I've been hearing some birdsongs lately that I can't identify, so I listened to the CD in order to try and figure out whose chirps and trills I've been hearing. With the CD's help I learned that a blue jay has more than one kind of call, so at least one mystery was solved!
