E Koford 20 Journal Mexico. 28 June 1969. Canyon del Nido, Sierra del Nido, Chih. streambed. 7700', last apparent "Limbik" Pica. By trail near streambed, occas- sional shrub of Broussonia copulini, with 4-5 gm green fruits. Bourza Mexican Jays; Flicker; Caver (2) & Western Wood Peewee. Yellow Periwain better to 18" drain, 100' tall. Finally saw a Steller Jay (require water?) (but now water apparent). No Tillerania in this canyon! Occasional shrub in white flower; 445 same as on Mesa de los Venados. 8400', draws of bird canyon start. Large patch of 100+ Aspen, to 25' tall, on slope. Saw Jays; Rufous-sided Towhee; 2 Red-fored Warblers in pine & Quercus rugosa foliage at times. Occas oak & Douglas Fir; about 20/3 crow corn of cedar. A few white pines to 80', with long closed crown, + some 10' seedlings. / 1000', started up last slope to ridge, then low oak brush, mimbos, manganita, scattered cedar & pine, rock older. (Doctylus ? sp.) Occas cut-grass clumps. / 1035, at noon, 9100' indented (cushion too high). Pine needle floor under 18" drain. Yellow periwain. Saw 1 Townsend Solitaire in pine, low. 4/10 cloudy on S side of peak. P. rugosa shrubs, W Bluebird, Nairy Woodpecker (fed small pine tuber). Chipmunks. / I descended branch of bird's nest's canyon, when a horse trail, searching for water (the last Oct.). at 8700', gorbeach perched 100' from me in pine and called gub-gub-'' '''; 50' up in pine (whited). As I descended, he flew to other perches. I saw the nest, 50' up in a flat fork of their pine branch, next to bottom of draw, essentially open about 200'. Much whitewool, but no food remains under. Occasionally adult gave a whistly call. / I descended to 8500'. Bird followed me 200 yds beyond nest, then left. Found no water, so went back up past nest. I was beyond & level with it on slope before adult returned to perch 25 yds from me & call loudly. Apparently at least two large white-downy young in nest, with some large black feathers. As I continued away, second adult perched near me; the two in similar plumage, & both gave the same gubs. / Now lower Mexican Jays.
