Wyer Phil 1972 Journal 36 320km NW Villa Hayes by rd. Sept. Boquerón, Paraguay Kilometers before Ecatari ranch, the forest is almost continuous when it is undisturbed. The rivers move back into well-defined channels then gradually dry up. The Rio Verde at its S edge of Ecatari Ranch, is at this time of year broken into isolated ponds (crammed with fish concentrated by the drying). Most, but not all, rivers & ponds are salty. We spent 2 hours on Ecatari ranch making a quick trip to [illegible] Berrie's proposed site on the R Verde. Mostly brush lower than the forest nearby. Very dense, fairly diverse. I checked a few palm-thatch houses for bats. Found some large droppings, some of which seemed to be composed of insect fragments. But no bats. Then the weather closed in & we left hurriedly. Berrie seemed to favorably impressed. Thought the R Verde area looked good for arboret, & that the large # of raptors model well for cats -- as an indicator of adequate prey. [illegible] Birds - Saw one large hawk, & crumenator, perhaps a savanna hawk carrying a 3 foot snake. Saw several things we did not see at the Chaco experiment.
