Preferred habitats include the birch- 
conifer type and the aspen-birch- 
conifer type. In 1904 and 1905 sight 
records indicated that this warbler 
was an uncommon summer resident al¬ 
though it was particularly abundant 
during warbler migrations (14,15). 
Specimens were taken and observations 
were made in 1929 and 1930 ( 21) . Ob¬ 
servations were made also in 1943, 
1946, and 1950 (22,29,35). Shelton had 
only two sight records. May 17 and 25, 
1963 (39). 
151. Blackpoll Warbler ( Dendroica 
striata (Forster)) 
This warbler is a rare summer 
resident and an uncommon migrant. The 
birch-conifer type and the aspen-birch- 
conifer type are the habitats most 
preferred. In 1904 and 1905, specimens 
were taken, observations were made, 
and the species was found to be common 
during the fall migration (14, 22 ). 
This warbler was reported in 1920, 
1930, and 1937 (21). Gilbert in 1946 
felt that the species was a rare sum¬ 
mer resident (30) . Shelton saw black- 
polls on May 19,21,and 25,1963 (39). 
152. Pine Warbler ( Dendroica pinus 
(Wilson)) 
This warbler is a rare migrant 
(30). In 1924 several were found, 
and in 1929 the species was recorded 
again (^1). 
153. Palm Warbler ( Dendroica 
palmarum (Gmelin)) 
This warbler is common during 
spring and fall migrations. Preferred 
habitats are the lake shores and 
beaches, beaver ponds and streams^ the 
birch-conifer type, the aspen-birch- 
conifer type, the 1936 burn area, and 
the clearings and partial clearings. 
In 1904 and 1905 specimens were taken 
and flocks of 30 to 40 were noted 
during migration (14,22). It was re¬ 
corded again in 1929, and specimens 
were collected in 1930 (21). During 
the 1940*s it was found in 1943,1946, 
and 1948 (27,29,36) . This is one of 
the first warblers to reach the island ' 
in the spring ( 30 ) . On a 1946 spring 
migration, 30 or more were noted next 
to beaver ponds and creek bottoms (29). 
Three were observed in the spring of 
1950 (35) . Shelton found this bird to 
be abundant during spring and fall 
migrations in the early 1960's (39). 
**154. Ovenbird ( Seiurus aurocapillus 
(Linnaeus)) 
This warbler is a common summer 
resident of the dense parts of several 
forest cover types. Habitat prefer¬ 
ences include the sugar maple-yellow 
birch type, the birch-conifer type, 
the aspen-birch-conifer type, and 
dense parts of the 1936 burn area. In 
1904 and 1905 specimens were taken and 
small numbers were reported,especially 
in damp, cool habitats along streams 
and in the tamarack swamps. No nests 
were found, but young were observed 
(14,22). They were noted in 1930 ( 21) , 
and found to be common during spring 
migrations in the 1940*s. Gensch (29) 
counted 10 of them, mostly in the 
sugar maple forest, and Lee and Krefting 
( 36) reported 54 song records from the 
sugar maple forest in May. They were 
regarded as numerous in the same habi¬ 
tat in 1950 (35) . A single dead oven- 
bird was found in the lighthouse on 
Menagerie Island, August 7, 1963 (34) . 
155. Northern Waterthrush ( Seiurus 
noveboracensis (Gmelin)) 
The waterthrushes are rare summer 
residents and are uncommon spring and 
fall migrants. Preferred habitats are 
the lake shores and beaches and the 
beaver ponds and streams. At least 10 
specimens have been taken on Isle 
Royale (21). Shelton made three sight 
records, one on Edward's Island (May 18, 
1962) and two on Tobin Creek (May 23 
and September 9, 1963 ( 39) .
