APRIL AND MAY BIRD-LIFE NEAR NEW YORK CITY Kl I RANK .. CH.AF.M.W April and May are excitinti; months for the field student. Throut^hout the winter they have been anticipated with an eagerness and enthusiasm which the events that so crowd them never fail to satisfy. Time cannot pass too rapidly until the calendar marks "April i;" then we live in the assurance that each day niay bring some old friend or wi^w acquaintance. The feast of spring follows the famine of winter. From April i to about May 10, birds increase in number daily: then, as the transient visitants pass onward to more northern summer homes, they become rapidly less abundant and by June 5 we have left only the ever-present permanent residents ami the birds which have come to us from the south to nest. As the days become warmer ami the weather more settled, so do the birds return with greater regularity. The times of arrival of the earU migrants may vary several weeks, from year to year, but the birds of May come almost on a given da . Ihe date of a bird's appearance depetuls primariJN , in most instaiucs, on the nature of its food. The length of its journe , or, in other wonis, its winter range, is also to be considered here; but since that is also, to a greater or less e.xtent, determinetl by food, we may consider the ever- important (juestion of fooii as the most potent sitigle factor t:()'ernin<r a bir(i time of arrival.
