Thank you very much for all compliments!
Ethiopia and Somaliland (I am not talk about Puntland and southern Somalia) is very safe countries now. You can travel there without any problems. Somaliland is a little bit more bureaucratic country, but still ok. In Ethiopia you can go outside everywhere also at night, but this is not true for Somaliland. You must be on hotel room from 18,00 p.m. to 6,00 a.m. You cannot go outside at night. This is restriction from Somaliland government. Also you must have policeman with you all the stay. So, I think it is much more safe, than the traveling e.g. in Kenya
This is problem, if you want to look for herps at night or during the hot months. In Ethiopia this is not problém.
Snakes are quite rare in Somaliland. I think, that they are common only in short period, which is best for them. This time is in hot and "wet" months - April - July...January is the most cold and dry months in Somaliland. It is winter there now...
Yes, the locality of Bitis is rather strange. To much stones and almost no vegetation like scrubs or trees. As told Gabri, good locality rather for Echis than for Bitis..., but we all know, that Bitis aritans occupies a wide range of habitats...I was very happy with this small adder, because it is ssp. somalica and not only "normal" arietans
