Verenna Winn, age 10, of Walnut Creek, California, for her question:

Can a bird see from both eyes at once?

Human eyes are set side by side and rather close together. They look out together and see the same view. But a robin's bright eyes are placed farther apart. Actually, he has an eye on each side of his head. Obviously he cannot use them to look straight ahead and see the same view, as we do. But he does see from both of them at once. His left eye has a fine view of the scenery on his left side. The right eye surveys the scenery on the right. Eyes of this sort show a bird what goes on to the left, to the right and also slightly ahead and behind. From the corner of one eye or the other, he can spot trouble coming from almost any direction. This is fine for the general picture. But when he wants a close up view of this or that, he turns his head and observes it through one eye    or the other.
