or perhaps they are toads, they have been croaking all weekend around my pond. I can't say that I have heard them before at this time of year. What are they up to?
Breeding? If so. it's a very odd time of year for it.
Some of mine were being so vocal I thought it was dogs barking in the distance!
:o
Strangely enough I have had frogs peeping up at me in my new pond, despite the frosts we have had lately. Something strange there!
