Purzelle, DO 1984 Propymyscus californicus Cage 2 (1461 - 1412) Hastings Reservation, Monkey Co., Calif. July 21 1000h - cleaned cage pups ♀ 9.1g ♂ 9.7g ♂ 1412 50.5g 1676 28.5g ♂, Imm 1675 28g ♀, Imm ♀ 1461 41.5g, dusted RED July 24 Redusted ♀ 1461 at 0900h. I had pulled the 2 babies off the mother and left them in the middle of the enclosure, about 15cm from the nest box. After releasing the mother back in, she made some attempt to take one of the babies/gups back into the nest box, but was startled by noise Julie made in the next cage and she escaped into the nest box. About 1min later, older pup #1676 (I know it was this one because after all of this I looked into the nest box and 1675 was hiding between the nest box and side of cage) came out and picked up one of the pups by the scruff of its neck, carried it around on top of the nest box for ~15sec (stopping to get a better grip) and finally into the nest box. Phenomenal !! Helping Behavior. I wonder the relevance of this in the field ??
