SUGGESTIONS FOR THE SEASON'S STUDY Birds and Seasons.— Compare the preceding outlines of the characteristics of the bird -life of Boston, New York, etc., with their accompanying lists of April and Mav birds. Miiiralion.t — I'oo much time cannot be spent in the field during the migration. It possible one ^iiould go out both in the early morning and late afternoon, visiting as great a variety of ground as opportunity permits. A knowledge of what birds to expect greatly increases the probability of seeing a species on or soon after its arrival. Weather conditions should be observed as closely as the migration itself, and the charts issued by the Weatlier Bureau, at Washington, should be studied. The blooming of plants, shrubs and trees and the advance of vegetation in general, together with the ap- pearance of various forms of insert life, calling of hylas, etc., should all be closely noted and these phenomena recorded with ;iv uuich detail as the arrival of birils. The record of each migrant shouUl ^how when it was Hrst observed, the tnimlHT seen. giving, if possible, the sex, if in song on arrival, if migrating singly, in scattered com- panies or in flocks, if observed to migrate during the dav. Succeeding observations of tin- same species should lie entered with as much detail as the first one in order to ascertain its increase or decrease in numliers.
