The female had the abdominal skin thickly glandular,
the male not at all - from which I judge that the
female does all the sitting; also it was the female
which was sitting when I took the eggs. On blowing
these eggs appeared perfectly fresh; yet there was an
appearance of drying. I suspect that "photography"
is disastrous to a good proportion of the subjects - putting
an end to incubation by leaving the eggs exposed to
the hot sun or by chilling them when the bird is off
a long period, "getting accustomed to the camera!"
5:40 p.m. - Mrs. G. has just located a Green-tailed
Towhee's nest, containing 3 1/3-grown young, eyes open and alert,
but down still predominating. Nest halfway to top of
ceanothus cordulatus thicket, in which it is located;
rim 520 mm. above ground. Nest supported on slanting
stems and appertaining fine twigs of the snow-bush.
Mass of nest far less than in fox sparrow; basal loose,
coarse layer lacking - more like brown towhee's nest;
wall rather thin and compact.

1/3 fledged) that Dixon had been photographing. Both parents
