Birds Call 

Birds Call

Many of the calls of birds are purposeful, being used to express pleasure or anger, or to apprise members of a flock of one another's presence. Others appear to serve no useful end. These are simply the utpourings of superfluous energy, the expressions of the supreme happiness that perfect health engenders. Since the vigour of birds is greatest at the nesting season, it follows that that is the time when they are most vociferous. Some birds sing only at the breeding season, while others emit their cries at all times. Hence the avian choir in India, as in all other countries, is composed of two sets of vocalists- -those who perform throughout the year, "the musicians of all times and places," and those who join the chorus only for a few weeks or months. The calls of the former class go far to create for India its characteristic atmosphere. To enumerate all such bird calls would be wearisome. For the purposes of this calendar it is necessary to describe only the common daily cries--the sounds that at all times and all seasons form the basis of the avian chorus.
