Nahe valley

The Nahe is a river in Rhineland-Palatinate and Saarland, Germany, a left tributary to the Rhine. The name Nahe is derived from the Latin word Nava, which is supposed to be based upon the Celtic origin for the wild river. So much for the small introduction with wikipedia support. But yes, talking about the wild river in Germany, I think it has earned the name. This river is one of the very last spots in Germany, where the Dice Snake (Natrix tessellata) occurs. In the Vineyards around the river lives another gem: the Western Green Lizard (Lacerta bilineata). I spent a nice day in the beautiful area near Bad Kreuznach.

One week in Croatia, part II

Lake Vrana -the biggest lake of Croatia- and its surrounding areas were proclaimed a Nature Park in 1999. This unique habitat is of inestimable value and is characterized by a high biodiversity. In addition to 249 registered bird species, there are also numerous reptiles. 

Habitat - Lake Vrana

The Blue-throated Keeled Lizard (Algyroides nigropunctatus) can be seen in rocky areas and stone walls.

As with most lizards, it pays to be patient again. The male specimens with the blue coloration around the head are particularly photogenic.

Exceptionally beautiful Dice Snake (Natrix tessellata var. flavescens). The Croatian name is "Ribarica", which means "fisherwoman". They can swim & dive very well and they prey mainly on fish.

I saw a couple of these handsome little aliens: Caterpillar of the Spotted Fritillary (Melitaea didyma).

Beautiful landscape and perfect habitat for reptiles.

Habitat - Stone walls and shrubby vegetation

Dahl's Whip Snake (Platyceps najadum) is one of the fastest snakes, I have ever seen. Luckily, I was fast enough to get pictures of this nice snake.

With about 50cm (19.7in) the Balkan Green Lizard (Lacerta trilineata) is by far the biggest lizard in Croatia. These "little dinosaurs" were a bit shyer than their smaller relatives.


At the very last day, just after dusk, I found the highlight of this trip: An European Cat Snake (Telescopus fallax) climbing in a stone wall of an old ruin.



...perfect conclusion!
