Boy, those sounds (of course) stump me. I have no reference frog sounds
here currently but your excellent web site.
I presume the sounds in your mystery recording at 5 sec and then 16 - 20
ARE male narrow-mouthed toads, and the lower chucking are the mystery
voices. Please pardon the probably dumb question, you may have already
covered it: could they be FEMALE Gastrophryne, stimulated by or answering
to the louder calling males from burrows or from other hiding places? But
no, you say they answer each other.
Danger: stories of no use to anyone:
When I was 16 in high school, and first recorded spring peepers in
Pennsylvania, I heard occasionally a trill among the loud chorus of
"peeps". Thinking I had a different species, I carefully tracked several
down and bagged them and took them home. They were all actually male
peepers, Hyla crucifer, and at home in a terrarium then sang the normal
peep call. I am not sure if this situation applies to your mystery voiced
frog, but I bet you have already thought of this possibility.
In Belize, in 1960, we caught about 30 tropical species after recording
their songs. We had no way to identify them, so we referred to the frogs
we already had recorded and caught by assigning call-descriptive funny
names, like the "cronk-cronk frog". The one that took us a week to catch
after first recording it (lived in burrows and retreated very rapidly), we
called the bastard. Good luck with yours.
