B. Hamilton 1967 Journal Jun 26 Parama City, Paramo, and Barro Colorado Island, Canal Zone but did not contain any very large trees except extremely scattered others. The trip was naturally for its lack of birds. Only two were seen in jungle, a Bare-backed Antbird, Thamnophilus delictus, a Xanthornis possibly genus Phaethornis, and Scott Brevlet Hylophilus flavipes. Only occasional birds were heard. Tree Pochard was a long print pigeon was observed on entering the island. Also observed and heard vocalizing many times was Hourle Monkey. I however seen them before. They are about 2' long splendid tail which was also about 2'. They were very fuzzy and a chocolate brown color. About 5 adults were observed with 3 carrying young in their bells. The ones we observed were all in an loose group. Scarlet Told and an Iron-pig-like Amphibian was also observed. At 11:30 it began to rain. Vocalization of both Hourle Monkey and Lizards seemed to increase with the approach of the rain. The rain was welcome to us because it cooled things off quite considerably. About 12:00 we were back at Solvency when we ate a hot lunch which was fine. We spent the afternoon till 3 sitting under the shade of building. Many small birds were in vicinity of lake. Observed were Black Vulture flying over. A Swallow flycatcher possibly Myiodynastes maculatus. a yellow billed flycatcher possibly Pirat-margine S-flycatcher, Myzetetes cyanea, Tropical Kingbird, Tyrannus melancholicus, Barnarquit, Cocreba flaviceps, Yellow-backed Oriole, Icterus chiricter, a small yellowish finch possibly Sicilis sp., and several other birds. Occasional lightning occurred with the thunder. We left island about 03:00. On way back we saw mostly some fish in river coming. Some Snellman was observed on river.
