Notes on the Different Birds.

2 only a single dove was seen as a rule. The other must have 
been sitting. I saw the last one on the Daily Beat in 1882, 
Aug. 9. South of the railway, however, 15 were seen Nov. 4. 
That was the only time I saw more than two together. In 1883 
a pair were seen April 23. At our house first from June 2. 
49. Catliartes aura (Linn.). XX M. of $ shot north of the 
house May 6, 1883. L. 711. W. 493. T. 265. B. 25. 
Seen oftenest singly. Most abundant in April and May, August 
and September. A single time (Aug. 28, 1883) three in com¬ 
pany. Must undoubtedly breed in East Swamp, and is hardly so 
rare in Wisconsin as generally supposed. King has only met 
with it in Pierce county. 
Ela7ioides forficatus (Linn.) breeds on the Mississippi but is 
hardly seen at Shiocton. Ictinia mississippiensis (Wils.) is 
met with in Wisconsin (C. L.). 
50. Circus imdsonius (Linn.). XX M. (N.) $ L. 468. W. 
333-337. T. 219-226. B. 27. $ (3) L. 513-544. W. 373-398. 
T. 239-252. B. 30-32. Not a few breed at Shiocton. It is 
most numerous during the autumnal migration. In 1882 
the first male was seen March 5. After the 27th almost daily. 
Makes its regular rounds, and was seen to fly by the house 
always at the same hour. In autumn it was noticed last the 
9th of November. In 1883, the first male, March 27. After 
April 11, almost daily. May 23, I found a nest in Shioc 
Meadows. It was built in the coarse dry grass of last year on a 
spot where water still stood. Contained four eggs, one slightly 
incubated. M. L. 45-48. B. 37-38. August 26, 1883, I shot 
two ducks (Aix sponsa) which remained lying on the water. I 
went to take them up, and was quite near to them, when a 
marsh hawk came and swooped down on the dead birds. The 
hawk remained sitting on one of the ducks, and flapped its 
wings many times as if trying to lift it. I took enough time 
to fetch my gun and shot the hawk. It was a large female (L. 
531). As a rule this bird was very shy; but on that occasion 
it sat quite still and watched me. 
51. Accipiter yelox (Wils.). M. of $ shot May 5, 1882. 
L. 277. E. 519. W. 169. T. 135. Probably often seen and very 
likely breeds at Shiocton as in other places in Wisconsin (King).
