Here is a video made by Andy and Flavie of a common toad (Bufo bufo) at Queen Elizabeth Forest Park in the Trossachs National Park this weekend. The chirrups of the toad you can hear on the video are release calls. Release calls are used during the breeding season by males who have been clasped accidentally by other males. In the explosive breeding of the common toad, males looking for females will often clasp any toad they see. By recognising the release call and letting go they do not waste breeding effort and can instead look for a female to form amplexus with.
