P. PEARSON 1950 33 surrounding terrain is grasslands. The total effect is totally different than the Villanueva region. Birds are much scarcer. Have seen Cryptophaga auri, Tsyrenus, tree swallow, and Smith saw Sparrowhike. Day completely cloudy, evening considerably cooler than at Villanueva. Camp about 2 miles west of Chaparel Cuevas de Tulumí, Tolima July 27 Left about 8:30 A.M. with Panlino, + mozo on horseback with one cargo mule. Arrived on ridge overlooking the Quebrada Tulumí at about noon by a route not the most direct. While looking for an easy way down the steep sides of the quebrada I spotted a deer standing about 30 yds. away. Called Panlino + the mozo to watch it while I went to reload my gun. The deer had not moved by the time returned (3 or 4 minutes). Shot it, a tough old? male. One of the caves can be seen from the hilltops and has an old abandoned cable, with gasoline engine running down into it from the hilltops - presumably to remove guano. The other cave, tho only one we have been in so far, is actually a huge limestone tunnel through which the Rio Tulumí runs. The ceiling is in places 75 or more feet high and there are additional holes + cracks in the ceiling containing many bats. All the holes were over the river, so I sent Panlino downstream with the bat net then fired a full load
