with seven singer series, electrified area 1800 tsuba (3.3 m^2 ea.) said Miura, on slope with tall bamboo (green leaves) and many dead or nr. dead trees (pines included). One & w. inf. outside fence. Seel & w. nr. molted control crown, + some scapular area too. A1 has advanced molt, including lumbar area and thighs, but two other ad. or a slightly more advanced. (Still not clear whether early molt means good or poor condition.)
Births and molt are ahead of A troop (2 whs. ?) I think. Animals look poor - some lean, scraggly. Partly due to fights in enclosure, I think. I saw 71 attack a & w inf, chase, catch, + bite him as if punishing.
Apparently enclosing gp. at start of mating season had no significant effect on mating season, but of course fence imperfect and outsiders got in. At any rate, estrus not delayed.

M. Kawai has compilation reports birth seasons many localities since 1958, and has made some graphs comparing. But apparently has done nothing toward correlating differences w.r. ecological factors. He thinks birth season somewhat early this year. I in the usually early gps. on Shodoshima, births on Mar. 3, Apr. 26, May 6. While in B on Mar. 1, Apr. 6, May 2.
Furuya Furuya reported that at Dogenzawa births in 1965 started April 24. In 1966, May 8, with 8 born (of expected 25-30) by May 27. At Kyoto univ., visited Suzuki, who spent a week at Jigokudani early May to census groups and count deaths. He said in group A, provisioned, w.r. about 35 members and 12 ad. 44, 3 births in April. But in troop B, not provisioned, 80-90 members including
