Frog IDs from Austria

Postby Gerald Ochsenhofer » Tue Apr 02, 2019 7:24 pm

Dear all,
we got some pictures to determine, discussed them and in the end had several opinions. Anyhow, most/all of us were not sure about it.
So I would like to hear some more opinions, best with comments on why.
All pictures were taken in Austria, precisely in Leithagebirge/Breitenbrunn/Purbach, in the beginning of March .
Species present should be Pelophylax sp., R. arvalis, R. dalmatina, (R. temporaria)

Tough as I only 'know' arvalis from around where I'm at, but the dark greyness looks like dalmatina to me.

Thanks for your opinions. I also would rule out arvalis for the reasons provided, but I thought that some could be Pelophylax, like dscn2488_2147.jpg or dscn2530_2150.jpg. I remember them also entirely colorless short after/during hibernation, but maybe my memory plays a trick on me.

Pelophylax usually has (clearer) an interruption in the caudal part of the dorsolateral ridges, which I don't see here.

Thanks, that's a characteristic I didn't know of.
