ABSTRACT. Maternal defensive behavior against predators may appear risky but is common in many species. Herein we describe maternal defensive behavior of mountain goats (Oreamnos americanus) against Golden Eagle (Aquila chrysaetos) predatory attempts. We found that Golden Eagles attacked goats in 1.9% of sightings (n = 311 sightings of active Golden Eagles over 12 years) but were never successful. Mothers always defended their young against Golden Eagle attacks. Predation by Golden Eagles on… Expand
Cooperative defence of female chamois successfully deters an eagle attack
TLDR
An unsuccessful predation attempt by a golden eagle is reported on a kid of Apennine chamois, grazing in a female kid mixed herd, and the attack was deterred by cooperative defence of females. Expand
Participation by a male Grant's gazelle in the defence of a fawn
TLDR
An instance in which an adult male Grant’s gazelle (Gazella granti) participated in the defence of a fawn against three black-backed jackals (Canis mesomelas). Expand
Conservation implications of using an imitation carnivore to assess rarely used refuges as critical habitat features in an alpine ungulate
TLDR
It is suggested that anti-predator behavior should be included in studies of resource selection when the goal is to consider habitat as a predictor for conservation success, and evidence suggesting a past mountain goat introduction failed due to lack of adequate escape terrain and subsequent recolonization of a predator is discussed.

TLDR
It was found that the contagious effect of alarm behavior among conspecifics and the investigative approach toward the threat were the types of risk assessment found most often, while mobbing was observed least often. Expand
Vigilance behaviour in Alpine ibex ( Capra ibex ) and Alpine chamois ( Rupicapra rupicapra ) kids
In prey species, vigilance is an important behavioural trait with regard to antipredator strategies. It has been studied intensely in animals. However, liŠle is known about vigilance in animal kids.Expand
Attacked from two fronts: Interactive effects of anthropogenic and biotic disturbances generate complex movement patterns
ABSTRACT Anthropogenic and biotic disturbances have the potential to interact, generating cumulative impacts on animal movement or, alternatively, counterbalancing or masking each other. DespiteExpand

What are the benefits of parental care? The importance of parental effects on developmental rate
TLDR
A theoretical model is developed that elucidates how parental care can affect offspring performance and which aspects of offspring performance are likely to be influenced by care and shows that parental control over offspring developmental rate can represent a significant, or even the sole, benefit of care.

Herd defensive behaviour of chamois,Rupicapra rupicapra, in response to predation on the young by a golden eagle,Aquila chrysaetos
TLDR
During the eagle attack, the females of the herd surrounded their kids and tried to protect them with their horns and bodies and the defensive behaviour was unsuccessful and the eagle flew away with a kid. Expand
Behavioural reactions of desert bighorn sheep to avian scavengers
TLDR
Previously undocumented encounters between avian scavengers and desert bighorn sheep (Ovis canadensis nelsoni) occurred only during the nursery season when lamb mortality was high, which may indicate that avan scavengers are potential predators or that desert bightorn sheep are unable to distinguish betweenAvian scavenger and avian predators.

In species with parental care, adults can often improve offspring survival rates by defending against predation, but in so doing they may incur considerable energetic expense, risk, and loss of timeExpand

I used retrospective analyses to investigate relationships among terrain type, reactions of prey, and age and sex of prey and outcomes of encounters between mountain sheep ( Ovis canadensis ) andExpand
Interspecific variation in antipredator behaviour leads to differential vulnerability of mule deer and white‐tailed deer fawns early in life
TLDR
It is raised the possibility that mule deer, and even whitetail, fawns may have improved survival in areas with higher densities of mule Deer females, contributing to the lower predation rates reported. Expand
Mortality of lambs in free‐ranging domestic sheep (Ovis aries) in northern Norway
TLDR
The negative association between lamb mortality and age of dam may be related to the quality of maternal care provided by ewes of different ages, particularly vigilance in the habitat of predators, as lambs grow older and more independent. Expand
Mortality of semi-domestic reindeer Rangifer tarandus in central Norway
TLDR
Natural mortality in a semi-domestic reindeer herd was studied by use of mortality sensing transmitters and predation by Eurasian lynx Lynx lynx was the predominant cause of death. Expand
Reproductive success in female mountain goats: the influence of age and social rank
TLDR
Social rank appears to be an important determinant of reproductive success for female mountain goats, especially among young females, and the positive effect of dominance on kid production decreased with increasing female age. Expand
Calf mortality and population growth in the Delta caribou herd after wolf control
TLDR
It is concluded that wolf control within the range of the DCH failed because the wolf trapping program did not remove enough wolves and was not conducted long enough to substantially reduce predation by wolves on caribou calves. Expand
Birthdate, mass and survival in mountain goat kids: effects of maternal characteristics and forage quality
TLDR
The results suggest that mountain goats are constrained to give birth in a short birth season synchronised with forage productivity, and a positive effect of mass on survival to 1 year when the sexes were pooled. Expand
