216 Notes on the Breeding of a few Western Birds. [March, 
and to find the nest of one pair. This seems to me an extreme 
western limit for the bird. The little Bell’s vireo (Vireo delli) 
enlivened the solitude of the chaparral with its warble, short and 
sweet. I found numbers of its little pensile nests, like those of 
the warbling vireo ( Vireo gilvus), and all within a few feet of the 
ground. The set of eggs, three in number, are very like those 
of V. gi/vus, but smaller and more pointed. Among the troupials, 
the hooded troupial (/cterus cucullatus ) and the Bullock’s troupial 
(Icterus bullockit) are the most common around Tucson, and the 
only ones whose nests I found. The hooded troupial builds a pen- 
sile nest composed entirely of grasses, and lined at the bottom 
with a few bunches of down. It is not unlike the nest of our 
orchard troupial. The eggs, three in number in every nest I found, 
are unlike those of the other troupials I have seen, but are marked 
with light and dark brown spots, chiefly around the larger end, 
and are of a bluish-white body color. The nests were all very 
thin, but firmly woven. A nest of the Bullock’s troupial which I 
found a few miles out of Tucson, is a very beautiful and unique 
structure. It is composed entirely of different colored twine and 
yarn, horsehair and bits of paper, and so well and thickly is the 
horsehair woven in, that the nest is very stiff and substantial, and 
scarcely compressible. A bit of newspaper woven in the bottom 
of the nest, bears the words, “special attention,’ and is very 
- appropriate. This nest contained five eggs, evidently a large set. 
They were of the size and shape of those of the Baltimore bird, 
but of a smoke color and thickly marked all over with lines and 
blotches, the lines forming a thick net-work around the larger 
end. The Carolina dove (Zenaidura carolinensis) is very numet- 
ous; and the white-winged dove (Melopelia leucoptera) was not 
uncommon, although not so abundant as back in the mountains 
where it breeds. I had the good fortune to find a nest of the lit- 
tle ground dove (Chamepelia passerina). J had seen several of 
these beautiful little doves, but did not know where to look for 
their nests, and only discovered this one by accident. It was 
situated between the horizontal forks of a limb about twenty feet 
from the ground, and consisted merely of a slight platform of 
grasses laid on the forks. It contained two small white egss 
pointed at either end and marked inside with the lateral trans- 
parent lines peculiar to the eggs of the dove family when fresh. 
This situation of the nest was contrary to my preconceived ideas
