A very noisy Frog

Can anyone tell me what sort of Frog this is. I was told it was

imported into Kent in the UK and has since spread to other counties.

It has a load distinctive call and is active during the day.

Very good photo ! The shadow taht reflect on the water is a little bit disturbing and i don't like that the leg is cutted but for the rest, everything is very good ! Thanks for sharing this moment !

Sorry...can't help you out with what type it is...looks like he has a maen case of mumps, though! :o) Greetings from Canada, Iren
