There were many Bullfrogs in this section of the pond, so many I could not begin to count them. In an area from the shore out to a large rock (about 10 ft.) there were about 50 frogs. Most of them appeared to be immature with a few adults here and there. The alarm squeak was given as the frog jumped into the pond from the bank. Other Behaviors: Emit Alarm, Squeaks. Equipment Notes: Recorder noted as "Nagra III N" and microphone as "Altec 633A" and parabola specified as "yes.".
