ence are the Blackburnian, Cape May, Tennessee, Bay-breasted and Wil- 

 son's Warblers. 



Contrary to the usual dates, the Blackburnian Warbler has arrived in 

 the past three years on April 29, Maj^ 5 and May 1, respectively. This 

 year the height of its migration was reached on May 19, when eight were 

 observed. It was last seen on the 29th. The Cape May Warbler also has 

 been coming ahead of schedule time, on May 4, 8 and 2. In 1916 it was 

 pretty steadily present until the 27th and five were observed on three occa- 

 sions. 



But the most remarkable increase has been shown by the Tennessee 

 Warbler. Up to 1915 I had only one spring and one autumn record of the 

 species. In 1915 it was observed several times from May 6 to 20, three 

 being recorded on the 19th. In 1916 it did not arrive until the 10th, but 

 immediately became the most conspicuous and constant songster of the 

 entire family, as many as half a dozen answering each other from adjacent 

 tree-tops. The climax of its migration was reached on May 22, when 

 sixteen were recorded and it remained common until the 29th. One 

 straggler was observed on June 2. 



I usually see not more than five or six Bay-breasted Warblers in a season, 

 but this year they were constantly present from May 11 until the 29th, 

 twelve being recorded on the 19th. Wilson's Warbler also arrived on the 

 11th and stayed till the 29th, singing freely and as many as four being seen 

 on two different days. 



One other unusual occurrence was a visit from a Blue-winged Warbler 

 in full song on May 19, as Dutchess County is beyond the normal range of 

 this species. The 19th of May marked the turning point of the warbler 

 migration and twenty-three species were noted on that day. — Maunsell

Mockingbird {Mimus polyglotios polyglottos) in Wayne County, 

 Michigan.^ Authentic records of the Mockingbird in southern Michigan 

 are extremely rare. The first known Wayne County record is that of 

 Mr. J. Claire Wood who found a pair breeding on Aug. 13, 1910, in Ecorse 

 Township, the nest containing three young (' Auk,' 1911, 269). This 

 locality is but a few miles from Grosse He where the second record was 

 estabhshed. Mr. George Thrall had a Mockingbird that remained practi- 

 cally thi'oughout the summer of 1913 on his grounds on the eastern side 

 of Grosse He. The bird was first noticed early in May, and had the 

 habit of singing vigorously from the peak of the barn, especially during the 

 early mornings. He was not aware as to whether it nested or not. From 

 a long residence at New Orleans Mr. Thrall is perfectly famihar with the 

 species. 



Major A. H. Boies wrote Prof. W. B. Barrows Aug. 6, 1906, from Am- 

 herstburg, Ont. " that a man there took a nest of the Mockingbird (pre- 

 sumably during that year)." Amherstburg is directly across the Detroit 

 River from the lower portion of Grosse He. It has been detected several
