Hardrickson 1950 Leptodactylus "obscura" Nov.22 Villavicencio, 1600 ft., Meta, Colombia, S.A. now describe the call as a non-musical "tic", almost metallic in character. (this after working with pitchpipe and whistle in an attempt to place call somewhere on the musical scale!). The call is about 3 notes above violin A. The duration I estimate at about 15 sec. Following are number of calls given (at fairly evenly-spaced intervals) over specified time intervals: 27 calls in 60 seconds 36 " " 60 " 10 " " 15 " 10 " " 15 " 8 " " 15 " 9 " " 15 " "tic" "tic" "tic" "tic" "tic" No marked pauses were noted; calling seems to be continuous, without any definite rest periods. Two individuals taken, one of them the calling individual. Other was on open mud slope, gently sloping, stream banks.
