1974 from the river pasture where we pitched our little tent. I set out at 20 large fold, Shams and 8 trap traps and cap. Saw one small bat at early dusk. Rails - three or four of them - in all the acagrias and cogs, making comical bubbling noises. March 26, 1974 near La Mina Color Acarí valley, Peru Tuesday. One live Gruppy in a live trap under a japper tree. I had to ethanize him to get a good look at his teeth - he looks so much like Rattus rattus. So we are going to try another night to get a few more. I decided to move up the valley, however, so drove for an hour with an eye open for the best places to put traps tonight. The girl whose family owned the field across from camp came to talk with us this morning - very charming. I spent the day in a shady spot near an acagria above La Mina (olive [= murato)], keeping comfortable in spite of the biting gnats. I saw a hummingbird nest with 2 feathers going in it, some snake and rat tracks in the sand by the river. In the late afternoon drove down the valley to an area we had spotted on the way up, just north of La Planta. Lots of stone walls along an out-of-use road to the river. It was really a pleasant spot - except for little biting gnats as evenhere, and a few mosquitoes (Anopheles!). I set out about 45 fold, Shams. Rails here too. Plus many kinds of singing birds.
