Seventeen Species of Bats Recorded from Barro Colorado Island, Panama Canal Zone by Eugene Raymond Hall

Our aim is to bring up to date the list of kinds of bats actually known from Barro Colorado Island, Panama. In 1952 Samuel T. Dickenson, Marguerite Schultz, George P. Young, and E. Raymond Hall spent the first 17 days of April (except Mrs. Schultz who left on April 8) on Barro Colorado Island. On eight evenings a silk net, 30 feet long and 7 feet high with a 3/4-inch mesh, was stretched in an open place to intercept bats. On the first five nights it was stretched in the laboratory clearing. On April 6 the net was erected in the forest across the Barbara Lathrop Trail 25 feet past its entrance; on the 7th and 8th the net was placed across the Snyder-Molino Trail at the Termite Cemetery, 150 yards southwest of the new (built in 1952) laboratory.

William B. Jackson was on the island from January 30 to June 6, 1952, as a member of a group from the American Museum of Natural History. On May 4 he set the bat net across Allee Creek at the beginning of the Barbara Lathrop Trail, and from May 5 to 27 he set the net in the Termite Cemetery where it was mounted between two small trees with its lower edge approximately 5 feet above the ground. Unless otherwise stated, specimens were caught in this net.
