Pearson - 1994 13 cores, no Cittaria llao-llaos. A "Parkguard" in residence at the Refugio. Then Adrian came by with a student (Bunge) who is planning to work on chromosomes and electrophoresis of populations of Chelemys and Geoxus with Milton Gallardo. I think they are interested in how isolated genetically are the populations on mountain tops. December 1- Bariloche. Drizzly and cloudy. Went to Parques and got my permit to collect some Ctenomys maulinus. They now require that half the specimens be deposited in Argentine collections once the data are processed. Then to the University to meet with Nora Ibarguengoytia's thesis committee. Her thesis: Reproductive biology of Liolaemus pictus. Her committee, me, Felipe Valverde, and Carmen Ubeda. Met a student there who is doing an owl pellet project on pellets from the Airport. She thinks they are from Bubo because she found a dead Bubo there. Helped her identify some of the material; she is using my key. December 2- Bariloche. Drizzle off and on. Long conference with Valverde, Ubeda, and Nora concerning her thesis. There seemed to be no question about it being satisfactory, but numerous suggestions for improvement. Also a visit from Michael Christie and from Noel and Andy Wesley. A letter from Ulyses Pardinas indicates that the specimen of Pearsonomys from Argentina is from Laguna Verde in Neuquen, does not have long claws, and was collected by Verzi and Alcover while they were collecting Octodon. I think it must be Abro sanborni. December 3- Bariloche. Mostly clear, but drizzle in evening. Mate with Abel, Lis, and children. He is in a new house, still under construction, in the Jardin Botanico (Topa Topa), with an arroyo, in the back yard with bamboo clumps along it, big cipres trees, maitenes. Then to Noel and Andy Wesley for dinner. One of Lorenzo Simpson's owls lives in the chimney at La Primavera. He had an aguila mora (Geranoaetus) that he raised from a nestling and it became completely tame, would perch on the roof of the house, come to be fed, etc. Then disappeared. December 4- Bariloche. Cool and cloudy all day. Went out to Eileen Lacey's study area 10 km N of the outlet of Lago Nahuel Huapi. She and John were intent on noosing a couple of the unmarked tucos in the colony
