DOWNLOAD EBOOKOrnithology in Laboratory and Field is intended as an aid to ornithological study at the college or university level. Students who lack the background knowledge usually acquired during a course in general zoology or biology should keep it handy for ready reference a standard elementary text on the subject. This book contains extensive material for purely informational reading, possibly enough to supplant the need of an additional textbook. Its principal purpose still complies with the title of its predecessors for it is essentially a manual to guide and assist the student in direct observations. All twenty sections, except the last (""The Origin, Evolution, and Decrease of Birds""), suggest methods and provide instructions for studies; and all conclude with an extensive list of references, frequently annotated, for further information. The twenty sections of the book can be taken up in almost any order and some may be omitted without affecting the instructional value of the others. A feature of this new edition is an introduction to birds and ornithology, intended for reading at the beginning of a course. The purpose is twofold: to show the significance of birds for study and to give an overall preview of ornithology, the subject, with emphasis on its wide scope, how it is studied, and some of the continuing and exciting opportunities that it offers for investigation.

DOWNLOAD EBOOKMiss Dana's class has front-row seats for one of nature's most awe-inspiring spring performances. In the branches of the fir tree outside their classroom, two blue jays build their nest. Shortly after the nest is completed, the female blue jay lays her eggs. The male brings her all kinds of food-an acorn, a worm, even a piece of a cookie! She guards her eggs closely, but the children are able to get a quick glimpse of them. Days later the children see the newly hatched baby blue jays huddled together in the nest. Three weeks later, the children say good-bye as the blue jays leave the nest for the first time. Without a single lesson, the birds spread their wings and take flight. This charming story with spectacular three-dimensional illustrations will bring out the nature observer in every child.
