We have quite a variety of birds on our 3 acre plot, and deciphering their unique calls is quite a challenge. We have the cardinal and woodpecker down, but the rest are giving us a run for our money, as many of the birds are out of sight, or don't stay still long enough for us to find the source of the call.
My daughter's recent inquiry as to if a call we heard was an owl (it was a dove), prompted me to search for sources that have birds sounds to show her what an owl in our area would sound like. During my search on the local library's website, I came across The Backyard Birdsong Guide. There are 2 editions: and Eastern and Central guide, and a Western guide.
I picked up the Eastern guide and I have to say that this is one of the neatest books I have seen. There are 132 recorded bird songs included, from birds all over the eastern and central US. Each bird has a 2 page listing featuring an illustration and some details about its habitat, location and song.
If your local library has a copy, ti is worth it to pick it up, especially if you are into birding. For more information, you can visit the companion site at www.chroniclebooks.com/backyardbirdsongs.
