Eritrea Clawed Frog or Peracca's Clawed Frog (Xenopus clivii)

I have observed this frog in a pond in the Northern Ethiopian Mountains. The species should be an Eritrea Clawed Frog or Peracca's Clawed Frog (Xenopus clivii); an endemic in species in the Ethiopian Highlands. Normally, clawed frogs are highly aquatic animals living in lakes or rivers with a permanent water body. But this very large individual lives in a small pond that contains only few weeks per year water and is highly contaminated by organic waste water. The next water source is several kilometers away and a way over land can be excluded.

Hornbills at the door

Sometimes, hornbills can be observed when they knock on doors or windows. I was wondering what they're doing, different species of them came to door and apparently they wanted to come in.

and uses it as soon as possible.
 Now,  that's the reason for their behavior; the houses are full with geckos.

A Christmas Butterfly

I saw this butterfly two week ago in the Awash National Park in Eastern Ethiopia. The species should be Citrus Swallowtail (Papilio demodocus) or Christmas butterfly.

Greater Blue-eared Starlings

They are always in groups, a little noisy, cheeky and curious; Greater Blue-eared Starlings. This one came to my room, perhaps to see what’s going on or to get some food.

Birds in Lalibela, Ethiopia

Lalibela in Ethiopia is a famous place for the rock-hewn churches, but the surroundings are home to many birds. Especially smaller ones, like bee eaters or starlings are very common.

On African Highways

Driving on African highways can be breathtaking and with a lot of scurrile situations, in every case it is stressful and sometimes dangerous. I made the photos last week on a tour back to Addis Ababa.

But there is a change in sight, the new highway from Addis to Nazret in Ethiopia:

Trithemis dragonflies

Trithemis dragonflies are one of the most common dragonlfies in Eastern Africa and can be found along rivers and ponds. This should be a Trithemis arteriosa, but  I'm not sure.

The hyena caves in Awash/Ethiopia

The hyena caves near the Awash National Park in Ethiopia are a tourist attraction for viewing Spotted Hyenas. They live in small caves and sleep there during the day time. After sunset, the hyenas come out for hunting and can be observed from the vicinity of few meters. There was different information about the size of the group; it is ranging between 40 and 250 (!) individuals. Nevertheless, hyenas were everywhere and it is a magnificent natural spectacle, see them coming out of their caves and leaving the area in small groups.
We were on foot there and had a funny walk back to the road in the night; a bit like Little Red Riding Hood in the woods. Excuse the quality of the photos; I made it with ISO 6400 in the darkness.

Reinecke's salt

Reinecke's salt is a metal complex with the formula NH4[Cr(NCS)4(NH3)2]•0.66H2O. In laboratory work it is used for analyzing cations like mercury or copper. It is soluble in alcohol and the photos are made of crystals precipitated from an alcoholic solution on a microscope slide.
