Observations on the behaviour and ecology of a threatened and poorly known dwarf antelope: the beira (Dorcatragus megalotis)

Observations on the behaviour and ecology of the beira (Dorcatragus megalotis) were made during spring 2004 in a wild population discovered in 1993 in a low mountain range in the South of the Republic of Djibouti.

The only encounter observed between two adult males resulted in the chasing of one by the other. Furthermore, the mixed-sex groups including a single adult male seemed rather stable, and their members used collective urination–defecation sites.

Abstract

Observations on the behaviour and ecology of the beira (Dorcatragus megalotis) were made during spring 2004 in a wild population discovered in 1993 in a low mountain range in the South of the Republic of Djibouti. Spring was found to be both a birthing and a mating season. Beiras fed in the first and last daylight hours, mainly on dicotyledons and in patches supporting trees and/or bushes. They spent the warmest hours of the day in the shade of trees, or in rock shelters when the temperature became too hot. Observed groups (n = 56) ranged in size from one to five individuals (mean ± SD = 2.70 ± 1.49). Most of these groups included a single adult male (62.5%) or no adult male at all (33.9%). The only encounter observed between two adult males resulted in the chasing of one by the other. Furthermore, the mixed-sex groups including a single adult male seemed rather stable, and their members used collective urination–defecation sites. From a behavioural point of view, the beira thus appears not very far from the dik-diks (Madoqua spp.), but differs from them by a greater sociability between adult females and its type of habitat.
