Blue-winged Warbler Once More Nesting at South Sudbury, 

 Mass.— On May 24, 1918, in a walk in South Sudbury in the Wayside Inn 

 region, I came upon a Blue-winged Warbler ( Vermivora pinus) singing. 

 The location was within a mile of the nesting in 1909, recorded in ' The 

 Auk,' Vol. XXVI, October, 1909, pp. 337-345. The bird disappeared after 

 several repetitions of his song before I had secured a yiew of him. But 

 there remained in my mind no uncertainty that I had heard the song of a 

 Blue-wing. This assurance, however, was happily substantiated by Mr. 

 Richard M. Marble, to whom I had mentioned the occurrence, who, 

 visiting the locality on June 19 and again on July 2, both times found the 

 bird singing at the same spot where I had heard him on May 26. Mr. 

 Marble writes me that he regrets that he did not have time to look for the 

 nest. But the fact of a male in song being present from May 24 to July 2, 

 a period of forty days, would indicate with reasonable certainty that once 

 more a pair of Blue-wings had nested in this region. The locality was 

 quite different from that of 1909, being a rather dry extent of second 

 growth in the rear of a sandy woodlot of white pines and a variety of 

 deciduous trees, but well supplied with undergrowth. In this woodlot we 

 have been accustomed to find year by year two or three Blackburnian 

 Warblers ( Dendroica fusca) singing throughout the month of May upon 

 their arrival, and continuing in June on the testimony of other observers, 

 giving assurance that the Blackburnian is a resident bird in this wood. 

 The Blue-headed Vireo (Lanivireo solilarius solitarius) is also found year 

 by year singing there much beyond the time of its migration. Both of 

 these species were represented in song on May 24, June 19, and July 2 of 

 the present year. Thus was had the unusual experience of hearing a Blue- 

 winged Warbler sing with one ear and Blackburnian Warblers with the 

 other, as probable nesting species. If the testimony presented may be 

 accepted as furnishing reasonably reliable evidence of a nesting of Blue- 

 winged Warbler in this locality in 1918, it may go on record as the second 

 authentic occurrence in this region of Massachusetts, South Sudbury 

 having the distinction of possessing both nestings within her borders. —
