Feb 17 Pinta Suarez, Espanola (Hood) Island, Galapagos
this nss, one of a pair of very excited Certhides, which
were near the net, flew in and another Tropidurus
got entangled in the lower tier. I managed to get
everything out and when I got back to camp I caught
a Dromicus going under the box with the stone on.
Spent the rest of the evening skinning the mocking,
which had already (belly) attracted flies (removed
as many of its eggs as I could). One bird near the
net I followed for some time. It walked a long,
moving 1 to 3 feet at a time, then stopped, looked
down, and would flip pebbles aside with 2 or 3
side to side movements of the bill (a much less often)
merely pick up something from the ground. It was
quite successful, and captured several small beetles.
Once this it moved a 150+ gm. rock on a pivot
about 2 inches [illegible]. The accomplishments of the Corvictus
are even more marked, however. A 7 plumaged bird with
a light bill I watched turned over a [illegible] gm. rock
which seemed to be resting flat on the ground; the
rock was somewhat spherical but still must have
required some effort to overturn. It kicked a 36 gm
rock about 2" away, 74 off the ground at the highest.
It seemed to be taking [illegible] grass stems which were covered
with gravel. Another bird I saw looked like it had
the root with loose grass stalks. It had much too
trouble with this, moving the stem with the tarsi
and at its angle of the torinuar, and holding the
