Blake furnishes three early autumn records of the Black-poll Warbler in the Garden in its migration south, namely, one of eighteen birds on September 24 and one of seven birds on October 5, in 1904, and one of a single bird on September 8, 1905. During the last five years and also in 1900 I saw a few Black-poll Warblers in the Garden in October, and in 1904 and again in 1908, the movement to almost the end of the month was continuous and abun- dant, ten birds being recorded on October 17 and th...irteen birds on October 23, in 1904, while in 1908 nineteen were counted on October 10, twelve of them being among the branches of one sycamore maple, twenty-one on October 14, and seventeen on October 19 ; upon the intervening days in i62 BIRDS OF THE PUBLIC GARDEN each instance the numbers were smaller. These figures indicate how abundant the migration of Black-polls was in the autumn of these two years, especially the latter. The latest lingering birds, two in number, were seen in 1900 on November 2.
