110 THE OOLOGIST 
I have found their ugly eggs in the 
little Least Flycatcher’s nest, in the 
well hidden homes of the Oven Bird 
and Chewink. They have even as- 
cended to the high, swaying nest of 
the Baltimore Oriole, to deposit their 
germs of destruction. 
The death of one full grown cow- 
bird means the presence in the world 
of ten other and useful birds, Thrush- 
es, Catbirds, and Ground Sparrows es- 
pecially, for in six catbird’s nests, 
eight thrushes, and four song spar- 
rows, cowbird’s eggs were found with- 
out exception. 
Hither-to, war has been waged most 
vehemently on the English Sparrow, 
but I herein urgently request all 
naturalists, all lovers of our Feathered 
Friends, to rouse themselves and make 
the steadily increasing number of 
COWBIRDS as steadily decrease.

AMERICAN RAVEN. 
I think I have made a rare find, and 
as so little has been said on this sub- 
ject, I will write it up. 
On March 26, of this year, while 
about thirty miles from Shandon in 
foot hills of Kern County, I made the 
following discovery. ‘ 
After hunting over a large canyon 
covered with trees on one side and 
very rocky on the other, and finding 
nothing, I went across to another very 
rocky canyon. On my arrival there 
I found a nest with five fresh Prairie 
Falcon eggs, The rock in which the 
nest was built was about one hundred 
feet long and from forty to one hun- 
dred feet high, The Falcon nest which 
faced the south, was placed in an old 
raven’s nest about twenty feet from 
the ground. 
On going farther down I found an- 
other large rock. This one was about 
one hundred feet high. I could see a 
nest up in a crevice. I threw up a 
stone and off flew Madam Raven. I 
hurried up the rock and soon came to 
where I could see the edge of the nest. 
I was at least ten feet from the nest 
and could plainly see four eggs. I 
tried to get something to fish the eggs 
out with, but couldn’t, so I decided to 
try to get there with rope. The way 
I swung around there wasn’t slow. 
When I reached the nest I found there 
were seven eggs. Was I surprised? 
I wonder! When I tested them I found 
the incubation to be started. 
I was very happy over my rare prize. 
Having one set, which you know is 
genuine, is worth a dozen doubtful 
sets. I give the following data: 
Nest placed in crevice of rock, ten 
feet up and one hundred feet down 
from top of rock. The nest was made 
of sticks and lined with wool. 
This is the first set of seven I ever 
took. Sets of six aren’t so common as 
those of five. 
The first set I found this year con- 
tained six fresh eggs. The eggs var- 
ied a great deal in size, but carried 
the same markings. There was one 
odd egg, that is in all sets I have ever 
taken or seen. This nest was in a 
pine tree about sixty-five feet from the 
ground, It was made of sticks and 
lined with cow’s hair. This set is in 
the Oological collection of Mr. A. E. 
Price. 
One more set was taken by me in 
a cliff about sixty feet down and thirty 
feet up. This set contained four 
very large, handsome eggs. The nest 
was of the usual structure. 
The raven is very bad about other 
bird’s eggs, and I have known them to 
eat chicken eggs. 
I must stop on this species, as I am 
very proud of my raven sets.
