a more exact analogy being pushing a heavy object with one's
feet, forcing the push with one's shoulder. Mostly the birds I saw
were working soft soil or ill humuses at the base of the brush, but
one I saw was at least 4 inches down when I scared it
away trying to see exactly what it was doing, and I saw
several birds 2-3 inches down. Birds may work the
same spot for 1-2 minutes after I find them and then
wait on. the one I (# 3/5) shot while [short while it was]
digging contained
much sand and a few small green seeds of (? Cordia) leaf.
Dr. Bartholomew said he saw this as well, the birds over-
turning the size of the trail. The compressed bill of
the species seems well adapted for this sewing as a heavy
wedge almost like the longer bill of any [oyster] catcher.
The jaw musculature does not impress me as
being nearly as heavy as magnirostris although the
bill is comparably deep; the structure is much more
like fatia. Not withstanding, the crops and gullets
contained the same soft seeds of nooguti (mostly) and
(? Cordia) buds, as well as much grass. Most had a lot of
fat near the bend, on the throat (below) and in the axilla,
the fat being quite yellow and requiring a little scraping to
remove (the fattest finches I have yet handled). All have
very worn bills and some signs of wing molt. One I hit with a
rock lost [primarily] almost all its feather from the opposite wing. One of the 9s
had at least 2 ova on the right side, as marked on the label,
plus a good left ovary 6-7 mm. long. The birds sang only sporadi-
cally during the midday and late afternoon. Mockingbird
