Some Belgian adder researchers found a yellow-eyed berus (instead of the more usual orange or red). Now I know this is (again) a matter of clinal variation, but who of you has got the yellowest berus eye on photograph?

Here in dear old blighty they seem to be all red..

This little fella is about as yellow as Ive seen..



Aspis in France however has the most stunning eye colouration..I know is the normal colour, but it does look the nuts..

I know this one is only a tiddler but it has a nice golden eye, its siblings were a more normal colour.

Group of yellow eyes:

The most yellow I found

this is the "best" what i can find in my photos

Very gold(ish).. I don't know if this one counts as being a Vipera berus bosniensis

Does this one count? I put it up on flickr because of the 'piercing' on its rostral scale - a new way to poke its tongue out without opening the mouth?..

not yellow, but almost black

hello together,

I stumbled over this ancient post and use the chance to show a rather golden eye .

foto was taken in situ, this summer in the Julian Alpes (around 1600 m a.s.l.);

best wishes,
Patrick
