If you haven’t already heard or
read, the Baby Fairy Wren article, then I’m here to give you a little
intro. In order for a Baby Fairy Wren
to get its supper it has to sing. The
Baby Wren will sing a perfect note, that they learn in their egg, this note is
called the begging call. But if the Baby Wren does not sing the right note, it
may either not get fed, or not get fed as often. This call is perfected to make
sure if another egg gets into the nest, it will not be fed.
