Although I have never seen them together, I believe there are two Toads in the Vegetable Garden. They are both of the same species, but I have no idea what that species might be. Of Toad species identified as Kentucky Natives, there are three likely candidates, and of those three likely candidates my vote goes to a Toad Species that has been given the name Fowler's Toad. And here I am told that a Fowler's Toad as a voice that sounds like, "the bleat of a sheep with a cold."
Now if you happen to be pottering in the Vegetable Garden, one or other of the
Garden Toads will make a little noise at you, if he or she has the idea that you
might not have noticed him or her. It is indeed a very peculiar noise.
Kind of petulant, sort of bad tempered, rather insistent, and does offer a
suggestion of "get out of my garden." Then , there'll be a little
very deliberate hopping around from the Garden Toad and you might hear the noise
again. In the past I have thought of this noise as a sort of low pitch 'quack'.
The kind of thing you'd get from a day dreaming duck.
