Finally a guide with pictures AND actual bird songs through QR codes. No more guessing if the bird you saw says twee wee wee, or whatever. Find a picture of the bird you saw, listen to its song. You can do the reverse too; grab a cup of coffee and your phone, and scan the QR codes for birds that should be in your area. Listen to the songs, and discover who’s hanging out on your property!
I hope they have a Canadian version too.
