a completed nest. She flew as I entered the room. I secured a ladder and soon 
held the nest and two fresh eggs in my hand. Some children were occupying this 
room so I did not dare leave the nest for further notes. I put another wire up, 
however, to furnish another nesting site. 
June 21, the nest where the young one had been seemed to be receiving addi- 
tions, and the sides were somewhat built up, but I could not see the birds around. 
June 25 the nest contained one egg and the ne.N;t morning there were two. A vis- 
itor told me that it was liable to be taken by some small boys who were there, so 
again I was afraid to leave it for observation and collected the nest and set, first 
taking a picture of it, showing the eggs. The parent birds seem to be very shy for 
hummingbirds, particularly around the nest. Unless I was entirely hidden, neither 
one would come near, though I 
could hear the tell-tale squeak 
first from one point and then 
from another of the nearby trees 
and bushes. 
There is a small stream which 
flows through the ranch, and it 
is crossed by a small foot bridge 
overhung by a willow and a sy- 
camore. This was a favorite 
hunting ground of the Blue- 
throats. About the last bird note 
heard at night and the first in 
the [morning was the squeak of 
this hummer coming from this 
point in the garden. 
The long diameter of the eggs 
is about the same as in those of 
the Rivoli but the short diameter 
is a little greater. This may be 
an individual characteristic of the 
pair whose nests I took. How- 
ever, the birds themselves are 
stouter bodied than the Rivoli 
and it is natural to expect their 
Fig. 21. YOUNG OK BLUE-THRo.\Ten HiTMMiNGBi Ri), to be larger. The nest is 
M.w 29, 1910 made largely of oak blossom 
hulls, and stems of the same, 
with a small amount of plant down intermixed. The whole is well tied together 
with cobw'ebs. The nest cavity is shallow and the edges are not incurved, differ- 
ing in both these respects from the nests of the other hummingbirds with which I 
am familiar. 
The place where I hear the other pair is near no house and I am anxious to locate 
the nest and learn what the natural nesting site is, man not furnishing a conven- 
ient substitute. Man\- hours of patient watching have failed to reveal it yet, but 
I live in hopes.
