154 Grundtvig—On the Birds of Shiocton, Wisconsin. 
yet empty, the third contained 6 fresh eggs. M. of these. L. 
15|— 15f. B. 12-12J-. In 1882, none shot before May 20. In 
1883, the first observed May 10. 
171. Cistothorus palustris (Wils.). XX Breeds apparently 
only in Shioc Meadows; but is found there by thousands. Almost 
always many nests are found in the vicinity of each other. In 
some places one sees large colonies. The nests are placed in 
the top of the long coarse last year’s grass. Later in the summer 
also in the new. In 1883, May 28, 21 nests were found. There 
were eggs in only one (3). June 3 there were eggs in 5 of 28 
nests. Most were built after June 5. Number of eggs 6, some¬ 
times 5. First egg laid in 1883, May 26. M. of eggs from h 
nests. L. 16-17. B. 12-J--14. In 1882 I saw none before May 
30. Had probably long been present in Shioc Meadows. In 
autumn they are seen scattered about, most in September. Shot 
one as late as Nov. 7. In 1883 abundant in Shioc Meadows 
May 17. 
172. Certliia familiaris americana (Bonap.). XX M. 3 
L. 144. E. 201. W. 66. T. 63. Not given as breeding in 
Jefferson Co. (Cooke), but that a few breed at Shiocton is quite 
certain. June 7, 1883, I followed one from tree to tree, but 
did not find the nest. In 1882, the first seen March 26. More 
after 28th. Most numerous April 24-26. Migration over about 
May 2. In autumn, most Oct. 7-11. Last seen Dec. 16. In 
1883 saw a single one Jan. 8. Afterwards not before March 20. 
Seems as if it must have gone away in the coldest part of the 
winter. A few, March 26. More after April 9. Most, May 6. 
Migration hardly ended before the 14th. 
173. Sitta carolinensis Lath. X Most abundant in sum¬ 
mer. Very common. Breeds in holes in trees, 10 feet or more 
from the ground. May 16, 1882, young were in a nest. 
174. Sitta canadensis Linn, xxx M. $ L. 104. E. 198. 
W. 66. T. 34. Only very few seen in the Daily Beat. In 1882 
one each day from May 21 to 23, and one Sept. 26. When I 
went to the Gfreat Wood south of the railway Nov. 3, I saw many. 
Nov. 4, I counted over 50. On the 17th there were still a few. 
On the 21st none. In 1883 it was not observed. This bird is 
said to breed in several places in Wisconsin.
