These races, how-ever, can be satisfactorily identified only on comparison of specimens, butsince, during the nesting season, one is unlikely to find any two of them atthe same place, the locality at which a bird is found will, at this season, go along way toward determining to which particular race it A Cooperative Study of Bird Migration IN RESPONSE to the request published in the January-February Bird-Lore, fifty-seven reports of the arrival, etc., of the Red-winged Black-bird, Robin and Phoebe have been received. We wish to thank ourreaders for these reports, and especially—in almost every case—for copyingso carefully the form we printed. The arrival of these early migrants is much more irregular than that ofthose species due in May. It is more dependent on the weather conditions,and this year all sections of the country report an exceptionally late mi-gration, owing to the frequent and heavy snow-storms and unusually coldweather in the early spring. The dates given in the following columns, there-fore, are far from normal. The January and February dates must refer, inmost cases, to wintering birds, not to newcomers. The Robin was at most stations the earliest species to appear and to becomecommon. After passing New York City, those that continued along the coa
