the island and fed in some trees near the light-house. After this 
date, the species was seen every day until October 12, and was by 
far the most abundant bird on the island. It was found every- 
where, feeding on the ground as well as in the tallest trees, and 
even at the water’s edge on the rocky beach. On the night of Sep- 
tember 3, a large migration occurred, and the bulk of the migrants 
were of this species. Thousands were seen about the light-house 
at this time, and considerable numbers in the trees all over the 
island, but on September 13 only three could be found. On Sep- 
tember 16, it was again common and continued so until October 
6, when nearly all disappeared. At Ann Arbor, it has been taken 
as early as September 5 (1896), and is often very common. 
134. (661) Dendroica striata. BusacK-POoLL WARBLER.—This war- 
bler was one of the rarest on the island and was only seen but a 
few times. The first one observed was on September 5. Two more 
(the last seen) were found on September 9. At Ann Arbor, this 
species has been seen as early as September 9 (1907), but it is 
never as common as the preceding. 
135. (662) Dendroica fusca. BLACKBURNIAN WARBLER.—This 
warbler was first seen on August 26, but not again until September 
5, when one was found dead under the light-house. The latter was 
the last record secured. Its rarity is surprising, as it was found 
to be rather common on Sand Point in June, July and August, 
1908, and it also breeds on the mainland west and northwest of 
the island. At Ann Arbor it has been seen as early as August 23 
(1908). 
136. (667) Dendroica virens. BULACK-THROATED GREEN WARBLER. 
—The first record for the black-throated green warbler was secured 
on September 8. After this date, a few birds were seen on Sep- 
tember 19, 21, 27, 28 and 29. On October 6, the birds came to the 
island in numbers with the myrtle and black-throated blue war- 
blers. All disappeared on the next night and no more were seen. 
The species may breed on the island, as it was found breeding on 
Sand Point in June, 1908. It is a common breeder on the main- 
land west and northwest of the island. It has been observed at 
Ann Arbor as early as September 8 (1907). 
157. (672) Dendroica palmarum palmarum. PatmM WaARBLER.— 
On August 24, the first individual of this species was seen in the 
trees near the light-house. It was not observed again until Sep- 
tember 5, when it came ,in small numbers with a big migration 
wave of warblers, thrushes and vireos. It did not become com- 
mon, however, until September 13, when there occurred another 
big migration wave of warblers and sparrows. This species was 
then represented by considerable numbers. Another wave occurred
