RIBBLE, DO 1987 PEROMYSCUS CALIFORNIUS (F) Nastings Natural History Reservation, Monterey Co., Calif. Aug 10. Finally caught # 835 w/ young at a 3rd nest above the second. I inserted a cotton ball with a good dose of metofane into the small (~ 30mm diameter) hole and she subsequently appeared at the second nest site. She retreated back when I tried to grab her. I then removed the cotton and she then jumped out of the hole immediately with young attached into my hands. The young were difficult to detach from her teats, but by applying firm but gently pressure to their snouts they let go. While processing the young, I left the mother in a trap. The young were moderately agile, eyes opened and they weren't biting. All squealed when handled. I ear clipped these # 11-13. They would have been old enough for ear samples and blood. Tagged 1952-Oct 12-#101 ♂ Immature. 127-65-23-14 = 12.4g. Ear-clipped. Grid CC-1 #835 Tagged 1945-see SPP A/cct-#D12 ♀ " 132-60-23-14 = 12.7g " " #1 4 Oct 87 White-tae Tip Tagged 1942-Oct 5 #D13 ♂ " 129-60-22-12 = 11.9g " " " After processing, I put each one back in the trap with the mother. I then opened the trap and held it next to the hole; she went back in with young attached and settled in the nest. Total handling time was ~15 min. The radio-transmitter was not on her and appears to be in the tunnel connecting the 2nd & 3rd nests. Success!
