Several Brown Tree- fers and White-breasted Nutcrackers were seen in the oaks. 1 Hylocharis leucotis was noted. 2 Hairy Woodpeckers were seen in the oaks at the foot of the ridge. Both were taken, but one met with an unfortunate accident during the process of skinning and was discarded. One large pigeon was heard, but not seen. Troglo- dytes brumeicolis was exceedingly abundant at all levels, probably the commonest bird in the area. At one time I had at least 10 fly- ing about the under-story vegetation in response to squeaks. Most of them were within 15 feet of me, or within 5 feet. Catharus sp. was heard but not seen.
