The same wonderful information about various birds as on the radio show and online emails is included in a handily-sized book with high quality paper.
Each bird or group has an illustration, but unfortunately they are not well done (imo) bc of the very thick dark lines used in the drawings.
In fact, some birds i'm very familiar with seeing would not be recognizable at a glance (eg. the VAried Thrush, Robin, Red-winged Blackbird, Nuthatch, loon).
Where drawings are necessary (to show how the Piliated Woodpecker thrusts its tongue into a tree), a small drawing could be in the corner.
I don't understand why the many fabulous, clear photos available weren't used instead.
