Great book and very useful tool to have
Format: Paperback
I had the older edition and lived it, but someone at my last job *borrowed* it and I never saw it again. This edition sends even better than the last, and I have that one five stars. Great pictures and the number of species covered means it's good in at least all states I've worked in.

Simply unputdownable
Format: Kindle
B N William’s field guide is fascinating. The book uncovers the bizarre reality beneath the polished propaganda of the Second World War, exploring the wonderfully weird truths where the line between brilliant innovation and sheer insanity vanishes completely. Every unusual piece of information has been verified using official declassified archives. I loved the story of Wojtek, a Syrian brown bear, who became a beloved and legendary figure, known for his unique story as an enlisted soldier. Read many more such stories and episodes in this book. You will enjoy them thoroughly.

Wonderful reading
Format: Paperback
It is a pleasure to “listen” to MLK Jr, and his description of the Montgomery boycott, mostly after reading the newest biography King, a life. Both books are highly recommended.
