May, 1921 NESTING OF THE STEPHENS FOX SPARROW 83 
on the nest. This bird also sat closely, not flushing until I nearly touched her. 
It then hopped off through the brush, uttering at times the usual Fox Sparrow 
chirp. This nest also held three eggs, with a trace of incubation. This set was 
sent to Mr. R. C. Harlow of State College, Pennsylvania, who sends ine the fol- 
lowing description: ‘‘In size they run .95x.69, .92x.66, .97x.69—measurements 
in inches. In color they are pale greenish white, the largest egg being almost a 
faint greenish blue, (chiefly) flecked, dotted and blotched with reddish brown 
and burnt umber, the markings tending to be heavier around the larger end, 
where they almost obscure the ground color. In one egg the markings at the 
larger end are practically solid.’’ 
A third nest, containing two infertile eggs and one young, was found June 
2 by S. Rich. This nest was one and one-half feet up in a buckthorn bush about 
one-half mile from the lake shore, and was similar in construction to the others. 
However, the eggs are quite different in that they are perceptibly smaller than

the average. These eggs are now in the collection of Mr. K. L. Skinner, of Wey- 
bridge, England, who has very kindly sent me the following description of them: 
‘‘The two eggs are both very blunt with very little small end. One egg is thickiv 
marked, the other very hghtly by comparison. In the light one the ground color 
is very pale greenish and both eggs when held to the light exhibit a greenish 
tint. In the hight one the blotches are drawn together at the larger end, not in 
the form of a zone, but in an irregular cap at the extremity. I can only describe 
the markings as much like the commonest type of song sparrow but they are a 
little smaller and more distinct. Both eggs carry a good gloss. Light egg meas- 
ures 20.x16.5 mm., the other 20.25x17. mm.”’ 
The season of 1920 we went after sets of the Stephens Fox Sparrow again. 
Our first trip was in the San Gabriel Mountains, back of Mount Baldy in Swart- 
out Canyon. Here, although the birds were only fairly common, we had unusu- 
ally good luck, finding three nests on May 31. Two were on the ground under 
buckthorn, and another about one foot up, also in buckthorn. Two of the nests
