Bird-voiced Treefrogs with Cattle

["Neville Recording" nevillerecording]

Hi David
I really enjoyed your recording of Bird-voiced Treefrogs. I have listened t=
o Walter Knapp and Lang Elliot's frog recordings but never really noted the=
 similarity of the sounds to bird song. They start off a bit like Spring Pe=
epers , which I am familiar with, but then go up tempo. Its also interestin=
g that two different sound producing mechanisms produce  similar vocal resu=
lts.
