Step 3:        UP OR DOWN

Generally, the earlier in the evening, the closer to ground the frogs will be. This is not always true, but works a lot of the time.

If you think the frog is within reach without climbing, locate the frogs proximity to ground by lowering yourself to its level while it calls.

Move your ear around till it’s very near.

You will know when you are very close, it will sound piercingly loud. It will probably be looking at you by now, so don’t make any sudden moves or the frog will jump somewhere else.

If that happens you will have to wait till the calls start coming again, and it might take ten or more minutes for that to happen.

If moving downward did not get you closer to the frog  get the ladder.

Get off the ground by at least a few feet and wait for the calls again.

Circle the vegetation as necessary, to measure the volume of the sound (and detect its nearest proximity).

You don’t need to necessarily see the frog to know where it is, within 2 square feet or so.
