so to the day of our departure. The distribution over the point 

 was uniform, but the birds, as is their wont, remained well down 

 in the trees and bushes. No birds in full spring dress were seen, 

 but there were all other plumages. 

 Dendroica cerulea. — Cerulean Warbler. 



None were found except in 1910. The first were noted on August 

 11, three, the next on the 13th, one, and after the 15th, when five 

 were seen, several were recorded every day until September 3, after 

 which date none were found. It is doubtful if there were any 

 breeding birds on the island. Conditions such as the birds breed 

 in in northern Ohio wei'e wanting anywhere on the island, as far 

 as we investigated. 

 Demlro-ica pensylvanica. — Chestnut-sided Warbler. 



It was present on August 18, 1908. In 1910 the first was seen 

 on August 19, two, and every day afterward several individuals 

 were noted. It was common on only one day, September 1. All 

 plumages were represented. Almost no individuals were seen ex- 

 cept in the immediate vicinity of the swamp, where the birds were 

 feeding among the button-bushes. 



Dendroica castanea. — Bay-breasted Warbler. 



It seems a little strange that none were seen except in 1910. The 

 first recorded was August 11, the next, the 15th, two, the 18th, 

 three, and after that a few every day until September 1, when 

 there was a great intlux. It remained common until we left. Until 

 it became common one had to look for the individuals in the 

 (lecidiious trees near the swamp, but the greater numbers spread 

 over the whole of the point. Most of the individuals were at least 

 tinted with bay on the sides. There were none in full spring dress. 

 Dendroica striata. — Black-poll Warbler. 



None except in 1910. The first was on August 11, two, and there 

 were a few individuals every day after until the 26th, when it be- 

 came common and remained so until we left, on September 7. The 

 first individuals of this and the last species had to be collected in 

 order to make certain of identification. It was usually possible 

 to approach near enough to make out the yellowish edging of the 

 wing feathers of this, or the bay tint of the sides of the Bay- 

 breasted. We found this species more widely distributed than the 

 last while its numbers were few, but when it became common :t 

 was everywhere present, like the last. Only fall plumages were 

 seen. 

 Dendroica fusca. — Blackburnian Warbler. 



It was found on August 29, 1905. The first in 1910 was on Au- 

 gust 13, one individual in nearly full plumage, and ever day af-
