For some simple tips on attracting bats, birds, butterflies, hummingbirds, frogs, lizards, insects, and pollinators to your garden, visit the National Wildlife Federation site. There also are links to pages about building a gourd house to attract purple martins, making the perfect bluebird box, and using humane tools for co-existing with deer.
In case you've missed an earlier recommendation for Anna Botsford Comstock's Handbook of Nature Study (Cornell University Press, 1986 reissue edition; $26.00), here it is again. First published in 1911, this book was written for school-aged children by a professor at Cornell University in New York. Almost a hundred years later, it remains a classic, filled with fascinating facts about a wide range of nature subjects, wondrously suitable for all ages. To see color photos of any of the wildlife mentioned, invest in any of the excellent field guides to birds, insects, spiders, and so forth.
