April 8, 1984 - ant
view, & in sun most of the rock. . After a couple minutes
a fellow drove by & stopped - Mr. Willie Bosco - he asked
if I had seen the birds. all of a sudden we saw a falcon
fly in from the south across the cliff face & land in a
snag up off to the left. It looked like a "heavy bird", with
yellowish feet, thick cap & very clean breast & belly. Very

came out from deep to the right of the large crevass, flew-
off & up to snag on right if cliff. The other falcon, that
had just landed on the tussrock, hopped behind it, appeared
to nibble at something for about a minute, and then
walked to the back of the crevass. Meanwhile, the

came back about 10 min later to land in a snag. Mr.
Bosco said he saw both falcons engaged in aerial
