 62 Bird -Lore The openinL^ of ponds and bays is followed, as we have seen, by the return of the Ducks and Geese ; the Woodcock coines when the thawing ground releases his fare of earthworms; the Sparrows appear when the melting snow uncovers the remains of the preceding season's crop of seeds. It is not, therefore, until a higher temperature brings into activity myriad forms of insect life that we may expect to find Warblers and Flycatchers. The region about New York is a favored one during the migrations. The nearness of the coast, the great highways of migration formed by the Hudson River valley and Long Island Sound give to the observer exceptional opportunities. But in no place, hereabout, can the migration be studied to better advantage than in Central Park, in the heart of New York city. The park, in effect, is an island surrounded by a sea of houses, and during the migration receives a greater number of bird visitors than any area of similar size with which I am acquainted. As a matter of local interest, therefore, in place of general notes on the spring migration in this vicinity — which have already been published in the ' Hand -Book of Birds ' and ' Bird -Life ' — I append records of the spring migrations of 1899 and 1900, in the Park, which have been contributed bv Mr. S.
