Field Notes
D.A. Bell
7 June 1990
Tiercel came in to W end of Cox I low, out of sight.
Right after that we saw the falcon (?) sitting high in
the prominent snag of SE gully. Definitely a different bird -
very marked breast, flank marking, thick horizontal bars, and
vertical tear-drops even up into loil, nearly to throat &
malar. The malar was quite thick, and there was a kind
of a white patch on nape. The ear patch looked smaller
than the tiercel's, and I think this falcon had more of a "hood"
than the resident tiercel. In any case, she looked big & dark, with
markings all up the breast. In fact, at first I thought she was an
imm. On looking at Wayne's reference photo, we concluded
that this is a new ?. So, both adults at Cox I. are
new this year. At the beach we decided to go over
to Iphigenia Pt. and check out the cliff from the
boat. Arrived there at 20:00, to immediately see the
falcon fly out to stopped tree snag, hah-hah-hahing,
with food in foot. The ? plucked the prey for ca. 1-2 min,
then flew right back to the eyrie ledge! She walked
into the ledge, and lumbered down - appearing to feed
ingoring. This lasted ~ 15 min, then she flew out &
landed on pinnacle in front. About 20:30 the Tiercel
appeared, landed in snag high on cliff. About 15 min
later he disappeared going W, returned 20:45 w/ prey,
corkscrewed over pinnacle ?&, landed on cake shelf of
pinnacle, ate, ran around abit, then flew to moss ledge
on E cliff. At 21:15 we left, saw falcon sitting on
pinnacle. Rain.
