Spotted hyenas
What are spotted hyenas? Spotted hyenas (Crocuta crocuta) are gregarious predatory mammals found throughout sub-Saharan Africa. They are the second largest African carnivores after lions, and they are more abundant than any other large carnivore in Africa. They look rather doglike, yet are more closely related to cats than dogs, and their closest living relatives are the mongooses and civets. A...
متن کاملMasculinized otoacoustic emissions in female spotted hyenas (Crocuta crocuta).
In humans and rhesus monkeys, click-evoked otoacoustic emissions (CEOAEs) are stronger in females than in males, and there is considerable circumstantial evidence that this sex difference is attributable to the greater exposure to androgens prenatally in males. Because female spotted hyenas are highly androgenized beginning early in prenatal development, we expected an absence of sexual dimorph...
متن کاملInnovative problem solving by wild spotted hyenas.
Innovative animals are those able to solve novel problems or invent novel solutions to existing problems. Despite the important ecological and evolutionary consequences of innovation, we still know very little about the traits that vary among individuals within a species to make them more or less innovative. Here we examine innovative problem solving by spotted hyenas (Crocuta crocuta) in their...
متن کاملPersonality dimensions in spotted hyenas (Crocuta crocuta).
Personality ratings of 34 spotted hyenas (Crocuta crocuta) were made by 4 observers who knew the animals well. Analyses suggest that (a) hyena personality traits were rated with generally high reliability; (b) 5 broad dimensions (Assertiveness, Excitability, Human-Directed Agreeableness, Sociability, and Curiosity) captured about 75% of the total variance; (c) this dimensional structure could n...
متن کاملSources of variation in the long-distance vocalizations of spotted hyenas
It has long been recognized that vocal signals communicate information about the age, sex and affective state of callers. However, the mechanisms by which these types of information are communicated are less well understood. Here we investigated variation in the acoustic properties of the long-distance vocalizations, called ‘whoops’, emitted by free-living spotted hyenas, Crocuta crocuta. Speci...
