Field Notes
D.A. Bell
June 7, 1990
in residence for 7 years, he & mate did not have young last year. This tiercel is dark & well-defined male, looks almost black; his white ear patch (behind male) is clean except that a "two-footed boot" of cup color (lighter than head & male) protrudes down into ear patch such that some small white patches are visible on either side of head, almost at the nape. Wayne says this is very unusual. The tiercel has light band just above the cere, and vent demarcation zw. clear lil & breast/flanks flecking. Flanks & belly flecking rather uniform. Slight pinkish to belly feathers - making an V between flanks (thigh) patches. Dark yellow feet, lighter yellow cere, faded eye lids. We can still hear occasional scream of another falcon. 12:25 Tiercel preening. He's had left leg tucked all the time. His nape, also has light V of whitish feathers. Quite distinctive. Wayne says this Cox I. cyrix hasn't produced chicks in last 3 years - although it has changed 2 ft's: 1 3yrs ago, 1 2yrs ago (Mes. Marauder).
Broke for lunch at 1300. Sat on leg overlooking Cloak Bay. Saw 1 minor otter in bay. Hitched/climbed up E face of Cox I., using some of the ropes Bristol had put in in '86 for his filming of the falcons.
14:15 - On top of SE end of Cox I., essentially near SE gully where we had seen the falcons earlier today. The Bald Eagles have a nest on top of the Windrow Pinnacle. The nest is on top of the grass at tops
