Salvioni and I radio-collared #1943 (♀ lactating) at station 9, 12. Radio is on channel #3. We had hoped to catch ♂ #1941 who is her suspected mate (RED powder was transferred from #1943 to #1941).

At this spot there is an old Westoma midden (very flat, small twigs only, and alot of litter) at the base of a small Bay tree (3m high). There is an apparent entrance at the top next to some rocks. Zzooius - we came out to grid MC-1 tonight to try and catch #1941 ♂ and radio-track #1943. 1943 was captured at 9, 10 without her collar. The signal was coming from the old midden so we began to carefully excavate the nest in search of the collar. There were several passageways throughout the midden with smatterings of red powder.

There was a lichen nest and moss nest that seemed fresh and the collar was in it. The collar had been chewed off just to the side of the transmitter, and the locking mechanism was chewed up. Obviously, some other animal had chewed it off, and based on the size of the chew marks
