P De Benedicti's 14c-y 23, seen Academy Bay, Santa Cruz, Is., Guadapozos. left the Darwin Station this A.M. about 5:30 with Robert Pyle to see what the old trail to the highlands looked like. Fairly light, but cloudy, by noon had cleared off. lots of song; along the trail to the other side of the town. saw many Geospiza fortis, perlingosa, and scandens. A pair of fuliginosa copulating. Songs are very confusing: lived here to spend some time just working them out and watching finches around the station now that I have seen most of the local species. A few C. parvula around; didn't see the magnificus. The trail to the highlands starts out in heavy, dry, scrubby vegetation which seems to be just starting to end. Trail tough but possible; rocky, dry. Troglodytes very common along the lower part. Further out to the beach the under vegetation gives out. About this point the first Certhidea turned up. A small almost olivaceous, yellowish-brown; beast a little darger. Feel him, very active. 2-3 songs, one "chewy chup" and buzzy wee-wee's sup; all calls very high pitched compared to the other species. Very easy and cliff. Near the middle of the dry zone found a pair of Mycerobas. Looks and sounds like a small cinereus. Pair flying quite a bit. ? nest in a dead trunk. Geospiza much commoner along here than at the station; many Peleus dendroica. Saw a nice yellow billed Cactospiza feeding on a dead tree fluttering back with the tail tip.
