P. PEARSON 1952 Nothoprocta (cont) (well covered with feathers) It was one of 9 embryos about a week or more to go. Dusk at 5:25, Temp at 5:55 42°F or 5°C. Approached nest at 6:00. Bird flushed when human 15 feet away (bird approached within 6 feet in a.m.) and shot (adj). Temp of 2 eggs was 32° each, metal temp of δ 40½°. Bird had been incubating between 1 hr and 1hr 25 min after an absence of 1hr 40 min to 3 hrs. Brought 5 of the eggs home and put them in humandrauma; Temp of drawer 60° at 7:15 p.m., at egg temp. at 6 a.m [illegible] was 3½°. Warmed 3 eggs under shirt till [illegible] 8:30. Then egg temp. was 28°. Opened them and found spontaneous movements and heart beat. 3 eggs left in nest overnight (all creaked) and warmed in sun to 29° showed no life, but 2 of these were small; weights of δ embryos from nest #6: 3½, 1½ no feathers, 5½ well feathered, 5½, 5½, 6½, 7 gms; 6 gms. Went back to nest #6 at 7:30 and saw a bird 60 yds from nest watching me at nest. Shot it (3697) Nest #7 - For parental schedule see AKP. Shot δ on nest at midnight. Air temp. 29°, night clear. δ cloacal temp 39½°C. Temp of 2 eggs 35½ and 36°C. These 2 eggs plus a third were left in nest, covered by feathers, the other 5 removed to drawer. Outdoor temp. at 6 a.m. was 26°. The drawer eggs were removed to sun at 9 a.m. and were 4½° at that time. Earlier they were probably 3½° as were the eggs from nest #6. At 10:30 they had warmed in sun to 39°. Opened them and hearts were beating. At noon brought the 3 eggs from nest home and opened them, (moon temp. 60°). Their temp. upon opening 27°. Embryos moved, hearts beating. 2 large eggs from this nest measured 55x35 39g; 56x36 42g; and a smallish one 51x35 35g. Weights of the embryos
