Hancock, and May 21 Mrs. E. K. Warren saw one at \'ine 

 Cottage Place and heard his wonderful vocal performance. 

 This is only a short distance from Dr. Hancock's, and it may 

 have been the same bird, as he was about all of June and July, 

 1918. At Warren Woods a pair were at the northwest edge 

 of the big south swamp May 24 and 26, 1919, and Dr. Han- 

 cock again reported a pair nesting at his place in June, 19 19. 

 Wilsonia citrina. Hooded Warbler. — This is a rare migrant 

 and a possible summer resident, as Dr. Gibbs found it nesting 

 in Kalamazoo County June 10, 1876, and in June, 1878. Bar- 

 rows, 1910, records it from several southern counties and says 

 "it undoubtedly breeds." At Birchwood Beach an immature 

 bird was taken on the dunes August 31, 1917, and September 

 4 two others were seen, one of them an adult male. 



Wilsonia piisilla pusilla. Wilson's Warbler. — This not rare 

 migrant was first seen at Birchwood Beach September 5, 19 17, 

 and as late as September 10. It was noted May 15 and 24, 

 1918, but was more rare than in the preceding fall. At War- 

 ren Woods only three were noted from May 15 to 21, 1918. 

 At Warren Dunes it was quite common from May 20 to 30, 

 1920, in the willows about the streams and ponds. 



Wilsonia canadensis. Canada Warbler. — This was not a 

 common migrant. In 1918 a few were noted from May 15 

 to 25, at Birchwood Beach. At Warren Woods a few were 

 seen from May 9 to 22, 19 19, and at Warren Dunes from 

 May 18 to Jvine 4, 1920. This species prefers the underbrush 

 and thickets for its habitat. 



Setophaga ruticilla. Redstart. — A common summer resi- 

 dent seen at Birchwood Beach in July, August, and September, 

 191 7, and after May 6, 1918. At Warren Woods it appeared 

 daily after May 7, 1919, and at Warren Dunes after May 8, 

 1920. It is usually found in the middle forest levels.
