The Birds of the Sand Dunes. 291 
five half-incubated eggs. May 30th another nest with four eggs was 
found there. Stoddard located six nests within a radius of one mile of 
Mineral Springs. 
81. Accipiter velox, Sharp-shinned Hawk. A much rarer breeder. 
March 11, 1916, we saw one at Mineral Springs; April Ist, two; August 
13, 1915, I saw one at Millers; May 12, 1917, one in immature plumage 
at Mineral Springs. 
82. Accipiter cooperi, Cooper’s Hawk. This species is a little com- 
moner than the preceding. It has picked on the stand of large timber 
in the Mineral Springs—Tiemont sector as being to its liking. April 1, 
1916, we saw four at the former place; May 2, one; May 25, 1914, Stod- 
dard found a nest with four partly incubated eggs 45 feet up in a tam- 
arack. July 13, 1915, he took four young, nearly ready to fly, from a 
nest at the latter place. The next year he located a nest in the same 
place, also with four eggs, on May 21st. We saw two there February 
il, I 
83. Astur atricapillus atricapillus, Goshawk. Probably a rare winter 
visitant. I saw one February 17, 1917, at Mineral Springs, carrying a 
cottontail in his talons. : 
84. Buteo borealis borealis, Red-tailed Hawk. A rather uncommon 
summer resident, commoner in migration. April 24, 1916, we saw two 
at Mineral Springs; May 12, 1917, one. 
85. Buteo lineatus lineatus, Red-shouldered Hawk. This is after the 
Marsh Hawk the commonest hawk. One or more can be seen at every 
visit to the Dunes. Dates are: April 24, 1915, one seen at Tremont; 
May 29, 1916, one at Mineral Springs; March 11, 1916, four at Mineral 
Springs; April 1, one at Millers; August 20, 1916, one at Mineral 
Springs; September 25, 1915, one at Millers. Mr. Stoddard found a 
nest at Mineral Springs. 
86. Buteo platypterus, Broad-winged Hawk. Seems to be rare here, 
probably common enough on some days during migration. Mr. Butler 
quotes Mr. C. E. Aiken, who says that it breeds in Lake County. I saw 
two at Whiting, Lake County, April 18, 1914. 
87. Archibuteo lagopus sancti-johannis, Rough-legged Hawk. Mr. 
Butler quotes Mr. J. G. Parker as saying that this is the commonest of 
the large hawks in Lake County in winter. I saw one November 30, 
1918, near Millers. 
88. Haliaetus leucocephalus leucocephalus, Bald Eagle. Up to within 
twenty years or less ago this great bird was almost a common sight in 
the Dunes, nesting regularly. When the number of foolish gunners in- 
creased, it had to go; but it still comes back from time to time as if to 
survey its former realms again. Mr. Stoddard saw a bird in the imma- 
ture plumage at close range at Millers, October 15, 1916, and Mr. W. D.
