Black Forest, May 2011

Postby Mario Schweiger » Mon May 30, 2011 9:48 am

Last saturday, between my Powerpoint-presentations at DGHT Ulm and DGHT Stuttgart, we (M. Wirth, R. Hähnlein, A. Pieh, A. Schmid, H.-P. Mattern and I) visited a Vipera berus population in the northern Black forest.
Unfortunately the weather was nearly bad - cold wind and complete cloudy nearly all the time. :(
Weather conditions got better when we had to leave :evil:

Some habitat shots:

But anyway, we have been able to spot a few adders.
It was quite hard to spot them, they were resting in wind proof depressions, mostly hided below dry gras, fern leafs or under Vaccinium bushes.

and frontal view


on a log I saw some kind of bee/wasp, catched another insect

"highlight" of the day was a fresh shed silverbrown male.
Its astonishing how the color and markings camouflage with the dry fern leafs

An interesting observation was something, I very often see, when grabbing Pseudopus apodus, but first time in my life at vipers / adders.
Erecting of both hemipenes

Due to the weather conditions (I hate to go herping with pullover and anorak :twisted: ) it was a fine day with a total of 10 adders and 4 Zootocas seen ;)

What is this? If you find a good day, how many adders would you find? :lol: Berus is incredible!

Great shots!!!

On the second trip a big black Vipera aspis male showed me his penis also. I don`t ask for that but he have done it.
But made no pics.

but now we have end of may 2011 and not middle of may 2009 ;-)

most probably in 2009 you visited that area around mating time and this time a few weeks later.

just for example weather for stuttgart (found nothing better)
2009 hours of sunshine in march/april: 280
2011 hours of sunshine in march/april: 464

for example here my best results:
time bevor mating: 41
time after mating: 13
based on around 75 day from 2006-2010

but keep in mind, this is from a low land population!

I think also we were very succesfull....I was two weeks ago in a other habitat and found (with big luck) after 3 hours 1 male....

By the way, it was a very nice day and a really interesting presentation :)
