106 Tue Wirson BULLETIN—NoO. 75. 
was seen at intervals of a few days until October 3, when the 
writer observed three. It has been seen at Ann Arbor as early 
as September 9 and as late as September 27 (1908). 
128. (652) Dendroica stiva estiva. YELLOW WARBLER.—The 
yellow warbler was a rare breeder on the island. It was seen on 
our arrival, and after this until September 9. 
129. (654) Dendroica caerulescens ce@rulescens. BLACK-THROATED 
BLUE WaARBLER—This species was first seen on August 31, in low 
trees near the path across the island. No more were seen until 
September 13, and it did not become common until September 26, 
when a migration occurred. The bulk of the birds that arrived 
on this date passed on the next night, and only a few were seen 
on the island until the night of October 5, when hundreds of them 
arrived with great numbers of palm, myrtle and black-throated 
green warblers. These passed on the next night, and no more 
black-throated blue warblers were seen. 
130. (655) Dendroica coronata. MyrrLte WaARBLER.—The first 
myrtle warblers were seen on August 28, when a few were found 
in company with the bay-breasted near the light-house. No more 
were seen until September 15 and 16, after which a few were ob- 
served on the island until the night of October 5, when thousands 
of them arrived in company with other warblers, mostly the palm. 
The last of this migration crossed the bay early in the morning, 
and, as the wind blew very strongly, they flew low and alighted 
on the ground all about the light-house and in the clearing. The 
bushes and tall grass surrounding the clearing were alive with 
them at this time. I noticed them feeding on seeds of the beach 
grasses and also on the flies that covered the sides of the house. 
The birds fed on the latter until they were gone, and then left 
the clearing (about 10 a. m.) and scattered over the island in 
search of food. The birds were very tame. On October T, only 
ten were found, and this number was about all that were seen on 
any day afterward. 
131. (657) Dendroica magnolia. MAaGNoria Warster.—The first 
bird of this species was seen on August 18, when an immature 
specimen was found in low willows near the east beach. It was 
next seen on August 24 and 26, near the light-house, and after this 
from one to three birds were seen on various dates until October 6. 
32. (659) Dendroica pensylvanica, CrmEsTNUT-SIDED WARBLER.— 
This warbler evidently did not breed on the island, owing perhaps 
to the absence of favorable conditions. A few were seen on Sep- 
tember 15 and September 29. 
138. (660) Dendroica castanea. Bay-BREASTED WARBLER.—This 
species was first seen on August 27, when a small flock came to
