In One Wild Bird at a Time, Heinrich returns to his great love: close, day-to-day observations of individual wild birds. Heinrich's observations lead to fascinating questions - and sometimes startling discoveries. A great crested flycatcher bringing food to the young acts surreptitiously and is attacked by the mate. Why? A pair of northern flickers hammering their nest-hole into the side of Heinrich's cabin delivers the opportunity to observe the feeding competition between siblings and to make a related discovery about nest cleaning. One of a clutch of redstart warbler babies fledges out of the nest from 20 feet above the ground and lands on the grass below. It can't fly. What will happen next?
