Sierra Hermit Thrushes nest: rim 800 mm above
ground; supported mainly by branches of a little incense
cedar (nest against its stem on one side) but also by
twigs from small lodgepole pine, whose stem is only
145 mm. from that of cedar - nest not exactly
between, though; total height of nest was 145 mm.,
diameter 160 mm.; divide diameter 65, depth 50;
height of cedar 4 ft., of pine about 7 ft.; bases of
these little trees surrounded by veratrum nearly
to height of nest rim; general site about 75 fee
from edge of willow bog and well-shaded beneath
group of lodgepole pines 75-100 feet high; also tall
firs nearby, from tip of one or another of which
male sings a good deal of the time (within a
radius of 100 yards of nest). It was thus I found
it. Female on nest sitting down low in it, bill
elevated, tail up at 80° angle from horizontal.
Contents four plain blue eggs, evidently near to
hatching; not taken. This is the nest Dixon has

75 feet away, and the old birds are continually
