Must-have. Encyclopedic. If you like birds, get it!

Frequently updated: thanks!

Great fun to get the birds into a sing-along.

Read *carefully* the description of a bird sound. (E.g., dont necessarily pick one of aggression) and you can get the birds to check you out from curiosity.

Sometimes call by region is also important. Get close to where you are. Dialects?
