The Nesting Season June 1 - July 31, 1977 NORTHEASTERN MARITIME REGION Reports were received from nearly every part of the /Peter D. Vickery Region. Such excellentcoverage makes the task of com- piling a seasonalreport easierfor the regional editor and Throughout the month of June rain plaguedmuch of more comprehensivefor the reader. the central part of the Region. Although this diminished the number of singing birds and made Breeding Bird LOONS -- In recent years the Corn.

New swallows, did not appear to suffer greatly from the wet England, however small numbers continued to breed in weather. Clearly, the severewinter in the south had a Connecticut and Massachusetts.This summer two pairs serious effect on many semi-hardy species. In New bred successfullyin Connecticut (NSP), and several pairs fledgedyoung in w. Massachusetts(RAF). In New Hampshire only 23 young were fledged; this figure be- ing dangerously low if the state is to maintain a stable population. Uncommon as a summering bird was the Red-throated Loon in Litchfield, Conn. (RAP). TUBENOSES -- Northern Fulmars remained off the New England coast into early June; two birds were seen off Chatham June 5 (WRP et al.) while 300_+ (3 dark- phase) were observed off George's Bank in early June (RRV). By the end of the month numbers had declined to 50 birds (BN). In the Bay of Fundy, two N. Fulmars were noted from the "Bluenose" June 24 (EWP). Cory's Shearwaters off George's Banks June 18-22, numbered 200 but by mid-July some 1500 were observed (B.O.E.M., RRV). Off Cox's Ledge, 23 Cory's Shear- waters were observedJune 28 (DLK, CW). Along the coast of Newfoundland an enormous concentration of shearwaters, with well over 100,000 birds visible at one time (80% Greater, 20% Sooty), was observed near Hampshire the following specieswere down from 1976 Cape St. Mary's in mid-June (JW, fide BMcT).
