14 till October 18. Saw only a single one till November 10, 
when they were again seen in flocks. In 1883 none seen before 
April 28. Most abundant about May 3. 
16. Spatula clypeata (Linn.). $ shot in a flock October 
30, 1881. Breeds in Wisconsin. 
17. Dali la acuta (Linn.). M. of $ shot May 4, 1883. L. 643. 
W. 270. T. 160. B. 54. In 1882 only noticed in the autumn 
about September 24; but surely always very numerous in mi¬ 
gration time. In 1883 seen singly from April 11. Very large 
flocks May 3 and 4. Some few must surely breed at Shiocton. 
In 1883 a pair were seen in the Shioc Meadows long after the 
migration was over. After May 26 only the male was seen. 
18. Aix sponsa (Linn.). XX By far the most common duck 
at Shiocton. Breeds abundantly in the old maples near the 
river. I have however seen its nest many hundred feet from 
the water. General] y the nest is in a tree-hole over the water* 
at a height of from 30 to 40 feet.' April 29, 1882, a female 
came out when one knocked on the tree; apparently she was. 
sitting. May 28, a female was seen with newly-hatched duck¬ 
lings. The assertion that the male does not accompany the 
female to and from the nest after she has begun to sit is untrue. 
I saw a male and female in company May 17, 1882. M. (N.) 
$ L. 462. W. 230. T. 114. $ (2) L. 411-443. W.201-211. 
T. 82-88. Often seen in large flocks, when they always have 
sentinels. Their cry recalls that of gulls. In 1882 this duck 
appeared the same day the ice broke up. Shot March 24. 
Abundant after the 31st. Last seen Nov. 4. In 1883, five the 
6th of April, when the water was not open. Most about the 
30th. Fewer than in 1882. 
Aythya americana (Wils.) and A. vallisneria (Wils.) are found 
in Fox River but hardly at Shiocton. A. marila nearctica 
(Stejn.) and A. affinis (Eyt.) were shot at De Pere. The last 
is said to breed in Wisconsin (King). I think I have seen them 
both in the Shioc Meadows, even in large flocks. In 1883, espe¬ 
cially from April 11 till 23. 
19. Aythya collaris (Donov.). XX M. $ (4) L. 417—430. 
W. 192—194. T. 50-59. B. 43—50. $ (2) L. 408—417. W. 189.. 
T. 54—63. B. 43. The color of the bill is often wrongly given
