adult male taken in the vicinity of Ann Arbor on September 9, 

 1896. In 1906, the species was noted but once, on May 2. In 



1907 it was first observed on May 18 and 19, but on May 30 two 

 specimens were taken, and on May 24, 31, June 2 and 9 single 

 birds were seen. In 1908, it was recorded but once, May 17, and in 

 1909 not at all. From the foregoing it may be seen that the species 

 is apparently somewhat more common than when Covert collected 

 in this vicinity, but that it is still far from abundant. 



Oporonis Philadelphia. Mourning AVarbler. — For the past 

 five years we have found the Mourning Warbler fairly common 

 (luring the spring migrations. In 1881 Covert looked upon the 

 ^Mourning Warbler as rare in this County, as shown by the follow- 

 ing statement: "This handsome bird is rare in the county, I have 

 records of but three specimens." Several have been taken between 

 1902 and 1909, but in the season of 1907 they seemed to be particu- 

 larly abundant. On May 28, 1907, four were noted in the vicinity 

 of Ann Arbor, two males being secured at that time. On May 31, 

 1907, Wood took two near the Huron River below Ann Arbor. In 



1908 and 1909, only single records were secured — May 24 in the 

 former year and May 25 in the latter. 



Icteria virens. Yellow-breasted Chat. — In Cook's list 

 (1893) Steere is quoted as stating that the species had not at that 

 time been obser\'ed at Ann Arbor, and Covert does not mention it 

 in his list. On May 20, 1896, Covert in company with Dr. R. 

 Wolcott and P. A. Taverner, found the species in song in an ex- 

 tensive swamp southwest of Ann Arbor. Several were seen on this 

 date and five secured. In 1903, ]\Ir. Covert wrote of the presence of 

 the species in Washtenaw County as follows: "Dr. R. H. Wolcott 

 and the writer found them very common in May, 1893, at various 

 places and secured a fine series of specimens; these were taken about 

 four miles south of Ann Arbor, Washtenaw Co. Again in the same 

 locality in company with Prof. Dean C. Worcester on May 4th, 

 1895, I .secured a pair (male and female) which were nesting." 

 (Bull. Mich. Om. Club, 1903, p. 60.) 



From 1896 to 1906 nothing seems to have been recorded regarding 

 the species, but on INIay 16, 1906, an adult male was taken by Wood 

 in the same general locality as the above. On June 28, 1909, 

 the species was heard singing by Wood in the same swamp, and
