Vol. XXXIV] Sropparp, Rarer Birds of Sauk and Dane Cos., Wis. 65 
quarter of a mile down the river, the only nest of the Red-tail that I have 
seen in such a location. The Red-tail is a common nesting species, all 
through the well timbered sections of this region, while the Duck Hawk 
has only been recorded as breeding in Wisconsin a very few times. 
7. Aquila chrysaétos. GoL_pEN Eacir.— Specimens of this eagle 
are not infrequently taken in Sauk County during the winter. A large 
female in my possession was taken in Feb., 1908, another, a male, was 
taken Feb. 23, 1909. That this species nested in Sauk County prior to 
1908, there can be no doubt. There was a deserted nest still in good state 
of preservation on a sheltered ledge about sixty feet above the ground, 
on the same bluff where the Duck Hawks were found breeding. It was 
littered with feathers of pigeons, ducks and other birds, and evidently the 
Duck Hawks found it a convenient place in which to eat their game. This 
nest was typical of the Golden Eagle, made principally of juniper limbs, 
some of which were over an inch and a half in diameter. Mr. Bert Laws, 
who frequently saw the birds and described them to me, informed me that 
the nest was used for one or two seasons prior to 1908. Before that time 
they had used a nest on an adjoining bluff, which was destroyed. I have 
seen specimens of the Golden Eagle on two occasions in the Baraboo Bluffs, 
in early summer. 
8. Cryptoglaux acadica acadica. Saw-wHer Owu.— Rather rare in 
Sauk County. One specimen taken March 4, and one on March 23, 1907. 
9. Phleotomus pileatus abieticola. NorTHerN PiILEATED Woop- 
PECKER.— A number of these fine birds still nest in the heavy river timber 
along the Wisconsin River, both in Sauk and Dane counties, and will 
doubtless hold their own till the original stand of timber is cut away, 
as they are extremely wary, especially in fall and winter, and breed in the 
mosquito infected river bottoms where they are seldom molested. There 
are only a few scattered patches of suitable woodland left in this region 
however, and those are fast disappearing. Have never observed them or 
signs of their work in the Baraboo Bluffs, which are heavily wooded, and 
in this region at least, they are almost wholly confined to the river timber, 
though family parties of four or five may be observed occasionally in late 
summer, somewhat out of their usual range. Have only two nesting 
records though they have frequently been observed during the breeding 
season. May 31, 1911, a male and female and three young were taken from 
a broken-off river birch-stub. Nest about twenty-five feet from the ground 
in partly flooded river bottom on the Sauk County side. June 11, 19138, 
another pair and three nearly fledged young were taken from a similar site 
on the Dane County side of the river. This nest was situated about thirty 
feet from the ground in an old and very brittle birch, which broke off at 
the base as soon as I started to climb, though the tree was nearly a foot and a 
half in diameter. The birds undoubtedly find this “ punk” wood very 
easily worked, as they had excavated an unusually large cavity, measuring 
entrance hole, three and a fourth by four and a half inches, with a total 
depth of twenty-three inches, and an average diameter of seven by nine
