There, Watson, this infernal case had haunted me for ten days. I hereby
banish it completely from my presence. -S.H.
I can state with great certainty that the Jocotoco Antpitta we discovered in
Ecuador would never have been discovered if we had not recorded its voice
and played it back. Even today, after much study and research, this bird is
still very hard to see. Bob Ridgely, Lelis Navarrette and I heard a voice none
of us had ever heard and recorded it. Upon playback this large, unique
Antpitta showed itself. This was in an area that had been studied before. This
is a
very rare bird and we still have not figured out its geographical patterns.
I had the same experience with the first confirmed sighting of Johannes'
Tody-Tyrant in Ecuador. I heard a song that I did not recognize. Played back
and
the bird appeared. There are other examples of this type of playback
resulting in new discoveries.
So, this is more evidence? If not enough, I have more!
That's my 2 cents!
