Abstract

In August and September, 1957, 22 netting stations were operated on and near the Atlantic coast from Nova Scotia to North Carolina. Two were manned for the entire two-month period, half of the others from 1 to 5 weeks, and the remainder for only a few days. Total bandings amounted to 11,613 individuals of 130 species, of which passerine birds made up 97 per cent of the total individuals. Nearly half the birds handled belonged to two families, Parulidae and Fringillidae. The 3 top species, Catbird, Song Sparrow, and Swainson's Thrush, comprised 30 percent of the total. A brief summary of location, habitat, and principal species banded is given for each station. At Middletown, R. I., 92 specimens of 3 species of Hippoboscidae were collected from netted birds. Eleven direct recoveries were reported in 1957, as compared with one each in the 2 preceding years. Two of the 11 were subsequently taken at another coastal netting station, and a third was trapped at a feeding station. The shortest interval of recovery was 5 days for a Northern Waterthrush that was banded at Plum Island, Mass., on September 2 and recaptured at Island Beach, N. J., on September 7, 1957. Observed direction of migration and of local movement at netting stations is discussed, as is distribution of recovery records. Three of the first four recovery records came from north or east of the netting station, quite contrary to the expected direction of fall migration. All cold-frontal passages during August and September are discussed, together with a brief review of their effects on migration at various coastal netting stations. The movement of a high pressure cell from the Great Lakes toward the Maritime Provinces results in a sustained northerly (southward) flow of polar air for two or more days after passage of a cold front; this produces several days of migratory activity, the second frequently being the best. If, however, the High drifts southeastward, stations to the north of its center soon experience a shift to warm, southwesterly winds and a rapid diminution of migration. The status of 21 species of 'rarities' is discussed. The importance of repeat records is reviewed, and examples are given of transients that remained at netting stations from one to four weeks. Station returns from prior years are summarized. Plans for the autumn of 1958 are announced.
