Hummer and the Hawk

She was no bigger than a finger, and he was larger than a chicken but that did not mean they could not be partners. The huge oak tree had room for both. It was the same for a pair of the two-legged animals. When one of them with a problem meets another with a different problem, sometimes both problems can disappear. For both the birds and the girls, it was like one minus one equaled zero, so both pairs of animals could concentrate on the things they shared. This is the ninth book of the Twenty Books Series, Wildwood Village Summer camp where 25 girls, ages ten to twelve, could spend a summer with each other and the local animals of central Oklahoma.
