RIBBLE, D.O. 1984 Peromyscus californicus Hastings Reservation, Mendocino Co., Calif. Feb 20 (Cont) Conducted 4 amos encounters this am. Summary - Home Visitor 1979♀ 1269♂ - 3 mins into warm up 1269 jumped onto the cardboard divider, then out! 12640♂ 126: 12640♂ 1225♀ No aggression Manicured approach, 1264 dug under and out! 030♀ 01300♂ First 2 mins the ♀ was clear aggressor, but the she escaped out under edge! 1364♀ last 12570♂ Mostly neutral until end when ♂ approached ♀, she attacked, and he retreated. Obviously, something needs to be done to prevent escapes. This afternoon I added ~ 2in of 44" hardware screen around all 4 bottom edges to Hopefully this will enable me to cover up the cloth screen with cloth and prevent escapes. Side view: Screen extending 2" in side. This PM on grid DC I dusted ♀1364 with GOLDEN PIGMENT at 4,13 (after lydic encounter, see below), and ♀ #020, 44.5g, lactating with ORANGE at 4,9. * Caught 020 this am, pregnant; thus, she gave birth today. Conducted a dyadic encounter between these 2 ♀s this evening at 2235h. I divided APPROACH category in "Approach" (no agonistic interaction) and "Offensive Approach" (agonistic interaction results) - have seen both of those and think I should record it as such. The encounter tonight has to be defined as Neutral, no aggressive interactions observed.
