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.
