the whole country but prefers to build in bushes near the water. 
I once found a nest nest placed between a slender willow branch 
and the stem of a young poplar. All other times in the fork of a 
branch. Of 16 nests only one was over water. Six were in wil¬ 
low, 4 in hazel, 5 in different bushes (1 in a quite small rose bush). 
3 nests were 1-J- feet, 6, 2-3 feet, 6, 4-5 feet, 1, 8 feet from 
ground. Number of eggs mostly 4. *In two cases 2, in one 
5. The 3d of June 1882 I found an egg on which the spots were 
collected at the small end (and I have found such later at 
Clinton, Iowa). June 10, 1883, a set of 3 eggs nearly without 
spots. On one there were only two. In 1882, first eggs laid 
May 31 to June 4. In 1883, June 1-8. M. of eggs from 13 nests. 
L. 14-19. B. 12|—13^-. In 1882 first male seen May 3. The 
day after, in many warbler-flocks. May 5, the commonest warbler 
in bushes west of Wolf River. May 14, uncommonly plenty 
everywhere only exceeded by Setophaga ruticilla and Dendroica 
pensylvanica. Migration ended May 26. In 1883 a few males May 
7. Afterwards daily except 9th and 11th. Most numerous the 
18th, but by no means in great numbers. Not half so many as in 
1882. Migration ended May 27. 
149. Dendroica caerulescens (G-mel.). xxx. M. $ (4) L. 
123-124. E. 194-201. W. 64-67. T. 50. B. 11. $ (2) L. 
119-126. E. 163-192. W. 61-63. T. 50. B. 11. It will be 
seen that the statement that this bird is the same size as D. virens 
does not agree with my experience. In 1882, several males 
May 8. Number increased till May 11 when I saw the firs't 
females. None the 12th and 16th-18th, but daily with these ex¬ 
ceptions; more or less numerous till the 23d. A single male 
was seen singing in a windfall May 31. In 1883, one male May 
12. Many in a large warbler-flock the 14th, 18th, two females. 
The 22d two males. Few compared with the previous year. 
150. Dendroica coronata (Linn.), xxx M. $ (5) L. 
133-151. E. 204-233. W. 72-77. T. 57-63. B. 11. $ (3) 
L. 133-139. E. 214-226. W. 67 -72. T. 54. B. 11. In mi¬ 
gration time the most numerous warbler. In 1882, first male 
April 5. A single one 10th, 12th, 14th and 18th. April 21, 
the first large flock. Afterwards more numerous each day. 
April 30, other kinds of warblers in the flocks for the first time.
