parts of the county, and even, as on one occasion, within the city 
limits of Oconomowoc. 
Zenaidura macroura carolinensis (Linnaeus). Mourning Dove 
A common summer resident, nesting abundantly throughout 
the region. During June, 1913, seven nests were under obser- 
vation, from which not a single young bird was raised, on account 
of unusually high winds and red squirrels. Quite contrary to 
the usual habit of the species, not one of these nests was below 
8 feet from the ground, while the two highest were in the upper 
branches of elm trees ( Ulmus americana), at an elevation of 31 
and 39 feet. 
Circus hudsonius (Linnaeus) . Marsh Hawk 
A common summer resident and nesting species in the larger 
swamp areas. Found continually along the Oconomowoc and 
Ashippun Rivers, and over the swamps near Dutchman’s Lake. 
Because of its low-flying habit and large size this hawk is shot at 
continually, and many are killed every year. 
Accipiter velox (Wilson). Sharp-Shinned Hawk 
A common migrant, arriving early^n April. Has been found to 
feed upon robin, bluebird, fox and white-throated sparrows, towhee 
and junco. 
Accipiter cooperi (Bonaparte). Cooper’s Hawk 
A common migrant and summer resident. One of the most, 
if not the most destructive hawk in this region, taking a steady 
toll of all available poultry and song birds. In 1912 a pair nested 
in a tamarack swamp near Golden Lake. 
Buteo borealis borealis (Gmelin). Red-Tailed Hawk 
A common migrant and occasional summer resident and breed- 
ing species, though at no time numerous. Like many of the larger 
and for the most part beneficial hawks, the red-tailed hawk is 
constantly prosecuted, while the smaller hawks, as Cooper’s and 
the sharp-shinned, are allowed to pass unnoticed. 
Buteo lineatus lineatus (Gmelin). Red-Shouldered Hawk 
A not uncommon migrant, for which, however, there are but 
few records. Much more uncommon than is the red-tailed hawk.
