R.D.Humillta 1967 Journal July 2 Loma de Secoy, 1300 ft., 22 km N, 11 Km W of Chanay, Dept. of Lima, Peru. White old bark on moss covered mostly leafless oak tree. I will try to photograph this one to properly describe it. The most common bird appears to be the Vermilion Flycatcher (Phaenicophorus rubiceps). The Rufous-collared Sparrow, Zonotrichia capensis and House Wren, Troglodytes aedon are also common. Two large hawks were observed displaying above Eucalyptus, a or Bangs tailed Skulter (Mastaca Catamitis) 2birds were also observed. Near the farm, House Sparrow Passer domesticus and Rock Dove were present. Columba livia on ground. A large brown rat was observed in the canopy of tree, at intervals approximately 4 years 1/2 days old. An unidentified Hummingbird was also observed. After Ray & Carl returned to mud house car, Fred & Ray then set traps; I wrote my wife and gave the letter to Carl to mail. He then left a short walk to drive to complete the preparation for our trip. At night we looked for Beden and caught 2. I was caught in side of building when we are staying. Before Carl left he told me not and said that the longitudes for this area +77°22' W and latit-de is 11°22' S. July 3 Morning was foggy and cold. At 0800 I checked a sext the maximum and minimum thermometers. The high was 66 and the low 52. Fred & Ray check their traps. Fred catch 6 Peromyscus like mice as Ray caught three. They resemble Phyllotis darwini but are slightly larger actually darker as have relatively shorter ears. We assume that perhaps they are a different race of Phyllotis darwini and there is some variation between him as when we caught the other - after checking Fred's traps Fred & I set not between two trees in open meadow
