Hopefully this is just a random incident relating to pollution etc .....

Attack by a bird or domestic cat, perhaps?

Rob Gandola said this on facebook "I think this is too big for mass predation and it's all around not just at the waterbody. Frogs dead and dying with no obvious wounds, many have cracked/dry looking skin"

[Sandra Panienka]

A colleague of mine reportet something similar a couple of weeks ago for a pond in our region, about 180 dead common frogs. But in his case the common frogs looked like they were cut open before other animals started eating them.

I think overkill by Mustela putorius.
I saw something simular a few years ago next to a breeding pond of Bufo bufo.

I think overkill by Mustela putorius.

That was my first thought as well, but Mustela putorius is apparently absent from Ireland. But maybe some other mustelid, such as M. erminea or M. vison could also do something like this.

Kids blowing them up with straws? I never tried and saw someone doing it, but I have heard of it.
Or maybe The Rook (Corvus frugilegus)?
