Introduction Simen mountains in Ethiopia, and as such presents an interesting act in the history of the Caprinae. Apart from the question of how the Walia ibex or its ancestors ever reached the Simen mountains, the only place it occurs, I would like to stress a further point: about half of the existing ungulate

Two Possible Competitors of the Walia Ibex: the Klipspringer and the Gelada Baboone Ethiopian region, the Klipspringer is probably the species best adapted to steep slopes and rocks (Ferrar and Walker 1974). Aspects of the social organisation and ecology of the Klipspringer are given by Dunbar and Dunbar (1974a). They found the Klipspringer to be a territorial animal that forms a

Further Mammals and Birds Living in the Simen Mountainselection of remarkable birds is given subsequently. The lists are given in order to demonstrate the living environment of the Walia ibex, the Klipspringer and the Gelada baboon. For the mammal species, apart from our own observations, I refer especially to various observations made by Dr. J.P. Mülle

For geographical location I have used the coordinates of the hectare field in which the group was observed. As each hectare field of the

Among several attempts aimed at gauging the absolute population size, there is none that does not imply a high degree of uncertainty.

The Habitat Selection of the Walia Ibex, the Klipspringer and the Gelada Baboon According to the Freparisons, a dependent variable has been used that is based on how often the hectare fields, visible from the main observation points Muchila Afaf, Kedadit and Saha, have been frequented by the Walia ibex, the Klipspringer and the Gelada baboon.

In a cross-table, the frequencies of the Walias observed were compared with the frequencies resulting from the environmental situation in Simen. This comparison is shown in Table 18.

In this chapter considerable emphasis is also given to these three, mainly spotted species, but, in order to widen the field of comparison, four additional mammal species are also examined.
