We don't currently have any birdsong CDs in stock. There is still one commercially available that I know of (Stokes Field Guide to Bird Songs: Western Region), but overall these products have declined in popularity with today's abundance of online/app options. Check out Cornell's "All About Birds" website or free Merlin Bird ID app, for instance. All the major field guides (Sibley, National Geographic, Peterson, etc.) now have digital app versions with integrated audio recordings as well.
Jack is very accurate and has good advice. If you can, download Merlin from the Cornell Ornithology Department on a smart phone. Then you can download their varias databases of birds, depending on where you might travel in the future. The application (app) is very easy to use once you try it. Each bird identification also has several versions of their songs recorded briefly. I use mine to attract some birds that I wish to photograph. Happy Birding.
