1B8 Grundtvig—On the Birds of Shiocton , Wisconsin. 
contained 6 eggs which a few days after where hatched. 
M. of eggs L. 22-24. B. 17. June 2, I shot one of the old 
ones that appeared to be the female. L. 219. E. 311. W. 97. 
T. 91. Must be referred to this form although only agreeing 
badly with the ordinary descriptions. It is to be especially 
noticed that the black stripes did not meet each other over the 
forehead (neither in the full grown young). The male fed the 
young. June 9 a little yellow-striped snake and two Dendroica 
pensylvanica were found impaled by the butcher-birds on a 
thorn of a wild plum-tree. The birds were so impaled that the 
thorns were driven in through the back of the neck (cervix) 
and came out on the throat (guttur). In 1883 I saw and heard 
this butcher-bird probably April 9 and 11. In the course of this 
and the next month I saw a single one but would not shoot it, 
vainly hoping that I might perhaps find a nest. 
135. Yireo oliyaceus (Linn.). XX M. of 13. (N) L. 
144-157. E. 230-263. W. 75-84. T. 50-57. B. 14. Builds 
about woods and swamps and is in Shiocton the commonest Yireo. 
Of 24 nests 10 were in trees over water (6 in maple, 3 in ash, 
1 in oak). Over ground the nests hung partly in trees partly 
in bushes (3 in oak, 2 in elm, 4 in other trees, (linden, maple, 
larch), 2 in hazel, 1 in willow, 2 in other bushes). Lowest over 
ground hung, three 3 feet, five 4 feet, four from 6-8, one 9, 
and one 14 feet. Over water, one 5 feet, four 6 feet, three 10 
feet, one 12 and one 15 feet. Number of eggs, 2-4, mostly 
3. Very variable in form and color. In 1882, first eggs June 
10-17. 1883, June 13-19. M. from 10 nests. L. 19-24. B. 
14-16. In 1882, the first was seen May 11. Next, 17th. Later, 
more and more. Most, the 23d. The last in autumn, Oct. 1. 
In 1883, several May 18. Many, 19th. Most, 20th. 
136. Yireo pliiladelpliicus (Cass.). XXX M. of 8. L. 
123-130. E. 194-205. W. 63-68. T. 43-47. B. 9. It has 
been said: “Almost indistinguishable from V. gilvus , except 
by absence of spurious quill. ” This is quite wrong so far as I 
have observed. 1. V. gilvus is larger. 2. In V. philadelphicus 
the second and third primaries are the longest and equally long. 
In a single specimen the second primary was longer than the 
third. In V. gilvus the third and fourth primaries are the
