    The owls have nested there and have hunted in the fields and circled in the night skies as time slowly slipped by. Every night, as the moon rises, a barn owl awakens and flies out to hunt. Feathered against the endless starry night, he swoops and sails to the darkened wheat field below and catches a mouse in his nimble talons. With outstretched wings, this barn owl returns to his barn nest and his hungry family, repeating the ageless ritual his ancestors have practiced here, in this barn, for at least one hundred years. Following the life cycle of the barn owl, this gentle poem evokes a sense of warm sunshine and envelopes readers with the memory of the scent of a wheat field.

    Because of his studies of the Eskimos, his discoveries of land, the application of new ideas and new methods of exploration, Stefansson was considered the foremost polar explorer of his day, and one of the few great explorers of all time. During a period of three or four years Mr. Stefansson has produced a creditable list of books about the Arctic. In some respects his service in publishing the results of his Northern studies has differed from that of earlier explorers. He has challenged our preconceptions about the Arctic. “Hunters of the Great North” gives details of Northern life such as have doubtless come within the experience of all Arctic explorers, but which are new to the average American reader. In short, it is an elementary text-book of the Arctic. Stefansson lived among the Eskimos of the Mackenzie River, studying their language and adopting their mode of life, and spending ten winters and thirteen summers in the polar regions. Among Stefannson's most famous discovery was that of a race of blond Eskimo on Coronation Gulf. Stefansson writes: "In the present book I have tried by means of diaries and memory to go back to the vivid impressions of my first year among the Eskimos for the story of what I saw and heard." In describing his confrontation with a polar bear, Stefansson writes: “I heard behind me a noise like the spitting of a cat or the hiss of a goose. I looked back and saw, about twenty feet away and almost above me, a polar bear. I had overestimated the bear's distance from shore, and had passed the spot where he lay. From his eye and attitude, as well as the story his trail told afterward there was no doubting his intentions: the hiss was merely his way of saying, "Watch me do it!" Or at least that is how I interpreted it; possibly the motive was chivalry, and the hiss was his way of saying Garde!” Contents I. PREPARATIONS FOR A LIFEWORK OF EXPLORATION II.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.
