LAND BIRDS. 399 
and over the Mexican Plateau to Puebla and central Vera Cruz. Accidental 
in Massachusetts. 
_ This bird seems to be purely accidental in Michigan. But one capture 
is recorded, a specimen taken by Rev. Chas. Fox at Owosso, Shiawassee 
county, in July, 1853. This capture seems to have been the source of 
several distinct records, one by Stockwell, in Forest and Stream, another 
by Miles, in his list of 1860; and this in turn quoted by Swales, 1903, but 
the locality given as Grosse Isle. Dr. Miles says of his own list “The species 
in the catalogue marked ‘a’ were obtained at Grosse Isle, Wayne county, 
by Prof. Fox and are given on his authority.” In this list Say’s Flycatcher 
is preceded by an “a” and it is therefore possible that a second specimen 
was taken at Grosse Isle, though it seems more likely that the intention 
was merely to indicate that it was one of Fox’s records. Miles’ statement 
is perfectly clear as to the Owosso specimen, and it would be a remarkable 
coincidence ifFox should have taken a second specimen of this bird at 
Grosse Isle. Unfortunately Fox’s original list, which was almost certainly 
published, cannot be found. The color of this bird is so unlike that of any 
other flycatcher that it can hardly be mistaken, but there is little likelihood 
that it will be met with again in Michigan. 
TECHNICAL DESCRIPTION. 
Adult: ‘Lateral tail-feathers edged with whitish; belly light cinnamon or tawny 
ochraceous. Above light brownish gray, the tail black; anterior lower parts light brownish

181. Olive-sided Flycatcher. Nuttallornis borealis (Swains.). (459) 
Synonyms: Nuttall’s Pewee.—Tyrannus borealis, Swains., 1831.—Muscicapa inornata, 
Nutt.—Contopus borealis, Baird. 
Known by the conspicuous tuft of white fluffy feathers on the flank 
together with its comparatively large size, seven to eight inches long. It 
is not likely to be confounded with anything except the Wood Pewee, 
which is smaller and unstreaked on the under parts. 
Distribution.—North America, breeding from the northern and higher 
mountainous parts of the United States northward to British Columbia 
and the Saskatchewan River. In winter south to Central America, 
Columbia and northern Peru. 
This is one of our rarer flycatchers, occurring in the southern half of 
the state as a migrant only, passing through during the latter half of May 
and returning from the north late in August. Like many other migrants 
it seems to be more frequently observed near the lake shores on the east 
and west sides of the state. In Ottawa county Dr. Gibbs recorded 
it on May 21, 1879, May 17, 1880, May 9, 1882 and May 25, 1883. One was 
seen in Kalamazoo county, May 22, 1885. Prof. Frank Smith records it 
at Macatawa, Ottawa county, as follows: One specimen each on August, 17 
1903, and August 21, 1904, and one specimen August 15, 1905. There is 
a pair in the museum of the University of Michigan taken near Ann Arbor, 
M 1896. ; 
Pe oicuoat the higher parts of the northern half of the Lower Peninsula 
this bird occurs sparingly as a summer resident. Widmann met with it 
near Harbor Springs, Emmet county, in July, 1901; 8. E. White took a speci-
