Abstract. This study was performed to gain more knowledge about the Bohor reedbuck time budget and vigilance in a savanna habitat. Detailed data on the time-budget were collected through focal animal observation technique to determine whether the time budget activities of Bohor reedbuck was affected by vegetation cover and to test if herd size, position in herd, the age and sex affect vigilance efficiency. We fit generalized linear mixed-effect models to assess how herd size, sex, animal… 

When can cropping rate compensate for increased vigilance?

Herbivores use vigilance to reduce predation risk and interact socially, yet it imposes a foraging efficiency cost. As individuals spend more time with their head up being vigilant, time available



Population status, structure and activity patterns of the Bohor reedbuck Redunca redunca in the north of the Bale Mountains National Park, Ethiopia

The Bohor reedbucks Redunca redunca (Pallas, 1767) were studied in the Bale Mountains National Park (BMNP), Ethiopia to assess their population ecology and activity patterns. The total count method

Vigilance behaviour and fitness consequences: comparing a solitary foraging and an obligate group-foraging mammal

It is suggested that foraging group size in herpestids is constrained by species-distinct vigilance patterns, in addition to habitat and prey preference.

Vigilance in Greater Flamingos Wintering in Southern Tunisia: Age-Dependent Flock Size Effect

The results suggest that young birds relied on the presence of adults, and hence more experienced individuals in detecting dangers, to reduce their vigilance and to increase their foraging time in order to satisfy their higher nutritional requirements.

Vigilance during Preening in Coots Fulica atra

It is indicated that flock size is the most influential predictor of vigilance in preening coots, followed by spatial organization, while nearest neighbour distance correlated positively with vigilance.

Vigilance and its complex synchrony in the red-necked pademelon, Thylogale thetis

Some vigilance benefits may be obtained from the presence of conspecifics even in species that aggregate only temporarily on food patches without forming more permanent social groups, as in red-necked pademelons foraging at night in nonpersistent aggregations in a clearing in rain forest.

Relationship between Distance to Cover, Vigilance and Group Size in Staging Flocks of Semipalmated Sandpipers

Controlling for food density, forager density and phenotypic attributes often correlated with distance to cover, it was found that as distance to obstructive cover increased, sandpipers foraged in sparser groups, were less flighty and to some extent less vigilant.

Determinants of vigilance behavior in the ring-tailed coati (Nasua nasua): the importance of within-group spatial position

A comparison of antipredator vigilance between coatis and sympatric capuchin monkeys is consistent with the hypothesis that terrestriality leads to higher perceive predation risk for coatis.

Vigilance in Przewalski's gazelle: effects of sex, predation risk and group size

The results suggest that mothers are more vigilant suggesting greater vulnerability and that males may have increased their vigilance to compete for higher social ranks, but failed to find an interaction between group size and predation risk on vigilance.
