196. Termii-ora pin us. — Rlue-wingecl Warbler. 



Locally coinmon in swainpy woods durln,t!: the summer. I have 

 looked for it in vain in the swampy woods within a mile of the lake 

 shore, even in the migrations. The only Cedar I'oint record is April 

 27, 1908, when one was found a half mile east of the Lake Labora- 

 tory. What the influence is which keeps this warbler away from 

 the vicinity of the lake where typical breeding habitats are more 

 numerous than elsewhere I am unable to suggest. Of course it has 

 not been found on any of the islands. The median date of arrival 

 is April 29. Nests have been found May 10. My latest fall record 

 is September 21, lOOCi. 



197. Yennivora cliri/fioptcra. — Golden-winged Warbler. 

 Irregular and scarce in the spring migrations. The first record 



is May 7, 1894. It was not again seen until May 6. 1901, and was 

 five times recorded during that spring, the last date being May 1(">. 

 On May 9 a pair was watched for a considerable time because they 

 seemed to be getting ready to build a nest, but were not again seen. 

 In 1902 one was seen May 4. and three May H and 7. In 1903, one 

 May 11. 1904. one May 7. 1905. one May 17, and one May 23. 

 1906, one May 14. 1908. one May 11. All of these records are for 

 the immediate vicinity of Oberlin. most of them in a wood one mile 

 south of the town. All but one of the birds noted were in low sec- 

 ond growth woods or the brushy border of larger woods, where 

 water stands until June. It is hardly likely that this warbler nests 

 anywhere in the region. 



Vcnnlvord IciicoliroiicliiaHs. — Brewster's Warbler. 



Although this is regarded as a hybrid between the last two spe- 

 cies, enough interest attaches to its distribution to warrant sjie- 

 ciflc treatment here. It was first found in a thin woods just out- 

 side of the corporation limits of Oberlin, May 23. 1902, singing the 

 half Blue-wing and half Golden-wing song. One was again closel.v 

 studied in an adjoining woods on Ma.v 28, singing the same song. 

 These two birds acted suspiciously like nesting birds, but prolonged 

 watching failed to substantiate the suspicion. In 1903 the records 

 are May 9, 12. 14, 16, IS, 19, all in the second growtli part of the 

 " South Woods." a mile south of Oberlin. one each time excei»t the 

 12th. when two were captured. These birds were singing a mixed 

 BIue-wing-Golden-wing song, and one was seen chasing a female 

 Klue-wing. In 1904 one was seen on May 10, 11, and 12, in the 

 woods in which the first one was found, but it was not singing. No 

 more were seen until 1907, when one was studied at close range at 

 the Lake' Laboratory. The last record is for the old " South Woods."
