Peregrinus Californicus (5) Bubble, DO, 1987 Hastings Natural History Reservation, Monterey Co., Calif. Aug 6(cont) I began digging using my hands and needle-nose pliers to pry soil loose. The clay was very hard packed and came out in chunks. She (#835) appeared briefly at one of the openings (see diagram above), and 5 min later I opened up the cavern and could see her (just big enough for her + pups) and at least 2, maybe 3 young. The nest was 'cup shaped', made of lichens & dried moss, and had an overhanging lip partially covering her & the pups. The pups were fully hared, gray on back, white on ventral side. I didn't see their eyes. While trying to decide how to reach her, she (with young attached) left the nest and climbed up into a connecting cavern, out of view. This cavern with the nest was about 3 feet big. I didn't want to dig anymore for fear of totally destroying the site. We covered the hole into the nest with clay chunks, and set 4 traps in the hollow in case she tries to leave this site. I needed a long-pair of forceps and I probably could have catched her. We left at 0840, and will return shortly to try again. - 1015h- we returned and just as I lifted the clay covering the nest cavern she went back up the same passageway as before. We closed all the traps and left. Tonight we hope to catch the young while the mother is away. 2340hrs - we caught #835 at station 4, 4' - 30m from the nest site. We left 2340hrs - we could get a signal on #835 at the same nest site. We opened up the cavern and she wasn't at the original nest site. Aug 7 #1929 ♀, mature pelage, subadult, perforate, nulliparous. 29g. Ear-tagged. Grid DC-1 & 5/10 We caught #835 at station 4, 4' - 30m from the nest site. We left her in the trap & tried to find the babies - No luck. Released her at the nest site and she escaped to a blind tunnel.
