This book is in the public domain, so even if Amazon does not offer it (at the moment I write this Amazon doesn't) you can still get it for free on the web.This illustrated book (2.4 MB, this is quite a lot for a e-book, the version without illustrations only needs 79 kB) explains how to build different kinds of bird houses, what size a bird house needs to be (depending on the breed of bird you are building it for), gives advise on where to place houses, how to build feeding shelfs and shelters, what to feed the birds and more.The book was written in 1916 and is aimed at the North-American public. A lot of the birds in this book only live in America, but there is also information on birds that live in Europe and Asia as well. You don't need to be a boy to enjoy this book! If you're interested in enticing birds to come into your garden this book can help you.
