212. Dendroica rirens. — Black-tbroated Green Warbler. 



Common during the spring migrations, scarce on the mainhmd 

 but usually common at Cedar Point in the fall. There is good rea- 

 son for believing that an occasional pair nests in the pine ^yoods 

 north of Elyria. I have seen a bird there during every week of 

 the late spring and summer, and its actions betokened the pres- 

 ence of a nest or young. It is found -everywhere that there are 

 trees, and is therefore common all about Oberlin and in city parks 

 as well as in the woods. The median date of spring arrival is 

 April 29, of departure. May 20 (Miay 28, 1907). The birds return 

 the first week in September and remain until October (Oct. IG, 

 1905). I found it on East Sister island on August 28, 1905, but no- 

 where else among the islands. It has been common in both migra- 

 tions at the Cedar Point sand spit, much more so during the height 

 of the migration season. 



213. Dendroica kirtlandi. — Kirtland Warbler. 



There are five records of this rare warbler, all for the Oberlin 

 quadrangle, and all but one for the immediate vicinity of Oberlin. 

 May 9, 1900, one was heard singing in the orchard bordering the 

 Oberlin corporation line on the south, and on May 11 one heard 

 singing in the " South Woods," and the one singing in the orchard 

 where the first one was noted was captured to make identification 

 certain. One singing male was found at Oak Point May 9, 1904. 

 One singing male in the " South Woods," Oberlin, May 2, 1906. I 

 have confidently expected to find tliis warbler on the Cedar Point 

 sand spit, but have failed to so far. 



214. Dendroica vigorsi. — Pine Warbler. 



Recoi'ds of this warbler are hardly more numerous than those of 

 the last species, if those for 1908 are excluded. They are : April 

 29, one male, singing, at Oak Point ; May 13, 1908 ; and from May 5 

 to 10 inclusive, 1908, one was seen and heard singing in pine and 

 maple trees in Oberlin. It may be that the scarcity of pine woods 

 in this vicinity is responsible for the few records. I am surprised 

 that Taverner and Swales were not able to locate it on Point Pelee. 



215. Dendroica i)uJ)narum. — Palm Warbler. 



Common as a migrant, both spring and fall. In the spring 

 it passes through in the brushy and tangle growths, seldom mount- 

 ing into the trees, but in the fall it is seldom seen aywhere except 

 in the fields and along fence rows bordering meadows. On the sand 

 spit it ranges along the crest of the sandy beach and down to the 

 water's edge, either in the bushes or among the grass. It seldom 

 ventures into the bushy growth along the marsh. On the sand spit 

 it is decidedly more numerous than on the maniland, and is even
