Jones — Hirds of Cedar Point. 109 



throat and with only a small patch of pale yellow on the breast. 

 It seems to me a little singular that iu the region where the Gokleu- 

 wiug is so scarce and so irregular, and where it clearly does not 

 breed this supposedly hybrid form should prove almost equally reg- 

 ular and numerous. Why should its association, not only here, but 

 elsewhere, invariably be with the Blue-wing rather than with the 

 Golden-wing. 



198. Vermivora ritJjncapilla. — Nashville Warbler. 



Common during the spring migration, less common in fall. It 

 is found ranging through all wood-lands, but less numerous in the 

 deepest woods, and inclined to be more numerous in the shade trees 

 in parks and about human habitations, and in orchards. It has 

 been common on the Cedar Point sand spit each spring migration. 

 I did not find it on any of the islands, except East Sister (Aug. 28, 

 1905), probably because my visits have been too early in the fall. 

 The median date of spring arrival is April 30, and of spring depart- 

 ure ^lay 21, the latest record being May 27, 1901. Fall records are 

 few, but they indicate a fall arrival during the second week of 

 September. My latest record is October IG, 1905. 



199. Venuirora cclaUi. — Orange-crowned Warbler. 



A fairlj- regular but never a common migrant in spring ; none noted 

 in fall. It has been rather more common along the sand spit on the 

 great days of migration than elsewhere. The median date of ar- 

 rival is May G. and of departure, May 19. The extremes are April 

 26, 1909, May 22, 1909. This warbler seems to prefer the brushy 

 areas of rather open woods, feeding near and on the ground. 



200. Yonnivora percovina. — Tennessee Warbler. 



Common, sometimes abundant in the spring migrations, but usu- 

 ally scarce in the fall migrations. Comparing my experiences with 

 this warbler in this region with those in central Iowa, where the 

 birds were far more numerous in the fall than in the spring, I am 

 naturally led to the conclusion that the presence of Lake Erie pro- 

 foundly influences the southward movement. It was tolerably 

 common on Pelee Island on August 29 to September 1, 1905, but 

 was not found on the mainland that fall. It is more numerous in 

 orchards and about human habitations than elsewhere in spring, 

 but it may be found scattered through the woods during the height 

 of the migration. It has always been found in numbers on the 

 sand spit. The median spring dates are, for arrival. May 10, for 

 departure. May 22. Extreme dates are May 4, IS!>9 and 1904, and 

 May 29, 1908. I^all Oberlin quadrangle dates are September 16, 21, 

 26, and October 1. It was common September iO. 1898, hut only one 

 was recorded on each of the other dates.
