Field Notes Doug Bell April 6, 1988 08:50: Todd has begun chain saw over near W end of the rock. The falcons have shown absolutely no reaction to it, in spite of noise being clearly heard. 8:57- The female is still on snag C - she was preening, also wailed every minute or so. She has her back turned towards me - was stretching her right foot in that classic called foot falcon manner. Her back is very light slate grey and is two-tone - the secondary coverts and tertials are lighter than the upper shoulder & head feathers. 8:57- female wailed, is looking up the rock. I think she is trying to convince the male to go off hunting for her. I can see 6 faint dark bars, thin, on her tail. The tail tip is just barely fringed in cream. Her legs are pale yellow, as is her cere. The male's head is visible just over the ledge of the path - he's been sitting very calmly on the eggs wailing 9:04- female still warbling every minute or so; her rate seems to be increasing. I think she is missing primary no. 8 - as evidenced by a gap when she warbled her right wing. 9:12- I warbled her left wing, then turned sideways towards me so over her right side is visible & preening, scratching right ear often. She has substantial thick black barring on her flanks & thighs. It goes over to spotting/thin barring just below breast. There is a fair amount of pinkish hue to her upper belly. Her head is dark, with a thick malar strip such that she almost has a continuous dark cap, except for a white chin and a thin stretch of white
