Also Pull on grid MC cl caught #1212 O at station 10,10 with faint (also on 25 May - see Telemetry Data 25 May) Purple in its ears. Noticed he is not scrotal. I also redusted #1200, lactating, with GREEN powder at station 9,9. May 19 This AM or grid MC cl caught #1128 scrotal O at 10,10 with visible Purple powder in his ears. I returned him to the cabin and examined him in the dark and he definitely has PURPLE powder in his ears, face, and feet. He is most likely the mate of #1186 so I kept him to put a radio-collar on (Marco will probably arrive today). Also caught #1216 O at station 9,18 covered with BLUE-GREEN powder (visible in ears, face) - mate of #1205. This PM we radio-collared #1128, D#14 and released him at station 10,10 at 2245h.
