Jones — On T'irds of Cedar Point. 173 



Cedar Point saud spit. The bullv is gone by the middle of Sep- 

 tember usuall.v. Nests liave been found May 30. While there is 

 considerable variation in the rendition of the song, each bird be- 

 ing able to vary its song to a considerable degree, the song pattern 

 is so distinctive that novices have little difficulty in learning it. 

 As one might readily infer, this warbler is present on the larger 

 Islands where typical habitats are plentiful. 



225. Icteria vireiis.- — Yellow-breasted Chat. 



A summer resident which is increasing in numbers year by year. 

 Nearly every brushy tangle now harbors a pair. When my studies 

 of the birds of the region began in 1891 it was not easy to locate 

 a pair outside of two or three favored localities. Several pairs 

 nest along the sand spit. Three pairs nested within twenty rods 

 of the Lake Laboratory in the summer of 1907. The median date 

 of arrival is May 5. My latest fall record is September 9, 1899. 

 There were three young found in a nest on August (3, 1897. The 

 birds become silent and apparently slip away soutli without at- 

 tracting attention. My visits to Pelee Island have been too late in 

 the season for it. There can be little doubt that it nests there. 



22<;. Wilxoiiia niitiata.- — Hooded Warbler. 



The flrst record for the region is May 9, 1903. when two were 

 found singing in the old "South Woods." None were found the 

 following year, but since 1903, when one was found on May 9 and 

 another on May 22, both in the "South Woods," it has been regu- 

 larly recorded, seldom more than one at a time. It certainly does 

 not remain to breed. It has been found well toward the east end 

 of the sand spit about the middle of May. Apparently individuals 

 do not work much westward. There are no summer nor fall rec- 

 ords. 



227. Wil'<o>iia piisiUa. — Wilson's Warbler. 



Fairly regular as a spring migrant in limited numbers; record- 

 ed but twice in fall. It ranges along the sand spit in the bushes 

 bordering the sand plains. On the mainland it frequents the brushy 

 borders of woods and the siualler growths of the woods. It does 

 not sing much during its stay. The median date of spring arrival 

 is May 13, and of departure northward May 20, the latest spring 

 record being June 2, 1903. The fall records are September 8, 1904, 

 one bird ; September 14, 1906, three males in high color, and two 

 birds in immature plumage. One of the remarkable things about 

 this region as contrasted with central Iowa, is that this warbler 

 passed south in swarms in Iowa and is practically absent in fall 

 here.
