50 “THE OOLOGIST. 27(A} , \A\O 
rope twenty feet long and ten steps 
of my ladder. I then went up to the 
top of the cliff and fixed my outfit 
and went to look down into the hole, 
but the hole was very small and went 
in about six feet, as near as I could 
tell. 
In the same cliff remained another 
place they had made frequent trips to . 
about thirty feet up and I again fixed 
my outfit there, and the following day, 
climbed up to it. It was a small hole 
also, but luckily, only went in twelve 
inches, So I reached my hand in. and 
pulled the nest out. To my surprise 
I looked into it to find three eggs 
about one-third incubated. I give data 
here. 
Nest made of grass, cemented to- 
gether with saliva and lined with 
feathers. Three eggs measure about 
.87 x .52 inches, eggs white. 
There still remained one more cliff 
that was about a mile West of these 
two cliffs, where I had seen four of 
the Swifts flying around at different 
times, and on the 24th of May I start- 
ed for there with my outfit. I had the 
good luck to find one nest and secure 
the four fresh eggs inside of three 
hours after I reached there. The fe- 
male called out in the crevice and the 
male flew in making four trips 
into the hole inside of twen- 
ty minutes. This was a much 
harder nest to reach than I had 
supposed it to be, it taking one hun- 
dred and fifty feet of rope. But as I 
had a hundred foot throw line for my 
ladder, I had plenty of rope. I set my 
outfit and let the nest go for a few 
minutes, thinking I could find the oth- 
er nest, and I watched about five min- 
utes and saw a Swift fly in a crevice 
_ about ten feet to one side of the one 
I had found before. 
Then I went down and found the 
nest in a small crevice, and as the 
bird came out I could easily have 
caught her. I looked in and pulled 
the nest out, which contained four 
fresh eggs; the nest the same kind as 
the other nest I described. 
As far as I am aware there have 
been but few sets of these Swifts that 
have found their way into smaller col- 
lections. 
The next place I examined for 
‘Swifts was a large cliff in June, at 
which I had seen fourteen Swifts. I 
located two nests and could hear the 
young ones call out, so I gave up the 
Swifts for the season 1909.

Unusual Red-Tailed Hawk Eggs. 
Under the head of ‘“‘Unusual Eggs” 
a writer in the January OOLOGIST 
speaks of small eggs of Red-tailed 
Hawk in which I was interested to 
the extent of carefully going over my 
Own series and records of measure- 
ments for comparison. 
There are four sets of eggs in my 
series deserving of special notice be- 
cause they contain specimens repre- 
senting extreme types in size in one 
or both measurements. 
One is a set of two faintly marked 
specimens, one of which is a decided 
runt measuring 2.12 x 1.59 inches 
while its companion, measuring 2.28 
x 1.73 inches is unusually small, but’ 
comes within the limits of normal spe- 
cimens. : 
The second set was taken by E. B. 
Peck, Clifton Springs, New York, May 
5, 1891. Size 242 x 1.62 and 2.38 x 
1.79 inches. 
The third was taken by the writer 
in March 30, 1898. They were globu- 
lar in shape, the short diameter of the. 
three eggs being near the average, 
while the length of one reaches the 
unusual minintv™ of 2.07 inches, The 
other two eggs measures 2.13 and 2.22 
inches long. 
The fourth set i; very interesting in-
