NOTES ON MICHIGAN BIRDS. 1 
BY N. A. WOOD. 
There are a number of species in the ornis of Michigan which are so 
rare or seldom observed, at least in certain parts of the State, that 
all of the records obtained should be published. These rare birds belong 
to no one class, being occasional visitants, stragglers, forms that are 
nearing extinction, and forms that for one reason or another have never 
become common. It is the purpose of this paper to note the records 
for these species that have been received at the University of Michigan 
Museum in 1911 and 1912. 
Gannet (Sula bassana). 
The first Michigan record for this bird was obtained last year, when 
an immature specimen shot at Walker Lake, Livingston County, on 
October 19. 1911, 2 was sent to the museum. This species is a very rare 
straggler from the Atlantic coast, where it is known to breed on some 
islands in the Gulf of St. Lawrence. 
Evening Grosbeak (Hesperiphona vespertina vespertina) . 
A flock of about twenty evening grosbeaks was seen from January 19 
to February 19, 1911, at Ann Arbor. It seemed to have its headquarters 
about a box elder tree on Thompson Street. This bird is only very 
rarely seen in this vicinity. Six were seen on November 25, 1906, and 
it was rather common during the winter of 1889-90. 
Duck Hawk (Falco peregrines anatum). 
Another unusual bird in this part of the State is the duck hawk, a 
specimen of which was seen at a small lake near Ann Arbor, by Mr. 
E. Lolir, on April 15, 1911. This is a true falcon and lives on ducks 
and smaller game birds which it pursues and captures on the wing. It 
mostly follows the spring and fall migrations along the shores of 
the Great Lakes, but is occasionally seen inland. The writer saw one 
at a small lake in Lodi Township, in August, 1S80, chasing a flock 
of killdeer. Another was shot at Silver Lake, Freedom Township, 
March 10, 1884, and an adult male in the museum collection was taken 
at Ann Arbor in 1892. 
Sycamore Warbler (Denclroica dominica albilora). 
On April 22, 1911, one specimen of this species was taken on the 
north bank of the Huron River, between Ann Arbor and Ypsilanti, by 
F. Novy. This rare species probably reaches its northern limit in Mich- 
igan at this place for it has not been found farther north. The name
