【實用娛樂app】How to Study Birds|最夯免費app-綠色工廠好玩App

WATCHING birds, and studying and interpreting their lively ways is, or should be, a round-the-year hobby, for there is no time when there is not something of interest to see in the world of birds. But there is no doubt that when the year is at the spring, then is the time when most is to be seen, for then events crowd fast, one upon the other, with much coming and going, pairing, nesting, and rearing of families, and all the emotional intensity and physical outlay of the breeding phase of birds. We may therefore with reason decide to start our study of a bird's year at the advent of spring, and to this end let us begin our observations on birds with the return of the summer migrants, and see what we can gain from days spent in the fields, or by the sea-shore armed with nothing but binoculars, note-book and most important of all, an inquiring mind.Here is what you will learn inside...★ SPRING JOURNEY★ ENSURING A PLAGE IN THE SUN★ NUPTIALS AND NESTING★ THE EGG, AND THE YOUNG BIRD★ INHERITANCE AND IMITATION★ AUTUMN FLIGHT★ WATCHING BIRDS IN WINTER★ THROUGH THE EYE OF A BIRD★ COLOUR IN A BIRD'S WORLD★ A BIRD IN THE AIR★ PROBLEMS OF POPULATION★ AIDS TO FIELD WORK★ THE MIND OF A BIRD
