Drove into Mollendo and met Holt Hughes, then drove south to Mejia and about 10 miles beyond looking for a good mossy loma. The swampy plain at the mouth of the Rio Tambo is impressive. Lots of egrets, ducks, shorebirds, etc., surely a tremendous oasis for migrating birds. Best we could do is a steep gulley half-way between Mollendo and Matarani. A good road goes down it to an abandoned installation of some sort at the beach. (fenced, with a watchman). We camped partway down the canyon amid powdery dry soil and chalk, steep rocky slopes, and assorted green bushes down to Dry wash, a bit of dry "maize grass", a few small dry cactus cacti up in the rocks. A few days ago seen, two burrowing owls sitting out in the hot sun, and moustache rats in the powder along the road. Wrens + doves. Just before dusk set a complex toad like track included segments among angular boulder slides up on both sides of the canyon (dried weeds + some green bushes), along the dry wash which is a narrow gulley full of weeds and bushes in chalky soil, out along a wall and among boulders on the valley floor. Lots of mouse footprints around the edge of the vegetation along the dry wash. afternoon hot & bright sun, (how can the burrowing owls sit out there and take it?). A few doves at dusk, big + small shrews, march 21 night clear. My 70 traps had 3 mice, (along the bushes in the gulley), and 11 Phyllotis darwini.
