Field Notes D.A. Bell June 10, 1990 1.5 hours until 15:30. Wayne got 2 I'd - some as last year, but the tailed flew in strong winds (a glided over our heads, often stationary) for the whole time. We find again site on well-grown shelf cs. 30' down on other SW facing side of gorge. At least 2 chicks visible, and they are younger than any others so far. This site had 1 chick in 1989. Falcon sat well-screening, she made many close passes in gorge as Wayne went over side @ 16:00. I got good pictures of both ads sitting. Traced two wide malar, ear patch filled dorsally by light gray feathers and a couple darker flecks at run of patch - one of which is large (its one in front of other). Light, irregular patch proceeds nearly up to level of upper mandible, and has a small finger in two-side eye. Next by a large ear patch is filled dorsally from nose down to about 1/2 length of malar stripe (all left side description). Filled part of ear patch somewhat resembles Vietnam. He has two faint lighter patches between eye & cere on left side of head, one close to eye, one close to nostril. Right side similar, but less distinct distinct. Almost no band of lighter feathers above cere. 3 chicks? All tailed! The adults seem to have both very raspy voices. Their kee-kee-hehe seem to have a rasp to them.

From the side her flanks & breast present an almost specker-like pattern - as the breast of a European Gerhamb. Her longjointed bands are thin and long on flanks. The wide flecking on her flanks go all the way up to her shoulders, and present a neat appearance across the breast & belly. Her tail has thick
