Pearson - 1993 23 Akodon olivaceus 10 November.- 15 km W Bariloche (Colonia Suiza Road). Caught 7 at edge of grassy meadow (Berberis, rosa mosqueta, radal, nire, Mutisia, etc.). All were adults, all looked like good olivaceus, no yellow feet, tails of the four that were put up were 70,72,72,75. Only one was a female, vagina open, not lactating. Put her in a cage by herself, and put 2 of the males in a cage together, They sparred but soon snuggled together. Ate apple, but ignored cheese, green grass, clover. A couple of them squeeked when handled, but did not bite. 15 November- The two males have been living amicably. Not very interested in cat food; ate some carrot, lots of apple. Took the two males, 8053 and 8055, up to Ecotono and put them into cages with their two isolated female xanthorhinus. They seemed interested in eachother, no fighting or even sparring while we were watching. Karin and Nadia say that the number of xantho on their grid this year is much higher than two years ago, and that there is more bunchgrass and more rosa than before. They have never caught Phyllotis on their grid. 20 November- The captive female 8052 seems content but no litter yet. She eats lots of apple when she has no water, but very little when she has water. Yesterday gave her dandelions, Calceolaria blossoms, and green grass seedheads. She ate all of the dandelion flowers but seems not to have touched the rest. Ate rolled oats. 22 November- Put a newly caught Ako xantho in breeding condition in with captive female olivaceus 8052. They sparred at first, then became more friendly but never relaxed, even when in contact. The female olivaceus was much larger, longer tailed, and more aggressive. Preserved them both as specimens. She had resorbed embryos. Anita's xantho caught at Las Victorias, was cought next to the road in thick bunchgrass, but lots of bushes around, such as neneo. 2 December- A sample of 5 from Hipodromo look mostly like olivaceus. Two females with 6 and 9 embryos. Most of them squeak when handled.
