Adult male hyenas are more likely to be alone than adult female hyenas. Additionally, high ranking or dominant female hyenas are among the least likely to be alone than other adult hyenas. Source: JENNIFER E. SMITH, JOSEPH M. KOLOWSKI, KATHARINE E. GRAHAM, STEPHANIE E. DAWES & KAY E. HOLEKAMP, "Social and ecological determinants of fissionefusion dynamics in the spotted hyaena", ANIMAL BEHAVIOUR, 2008, 76, 619e636 doi:10.1016/j.anbehav.2008.05.001 However, reproductively mature natal males were significantly more likely to be alone than were either adult females (Z¼3.31, P ¼ 0.006) or weaned, prereproductive natal males (Z¼2.99, P ¼ 0.014). By contrast, adult females were no more likely to be alone than were weaned, prereproductive females (Z¼1.13, P ¼ 0.52). On average, immigrant males (N ¼ 67) were found alone during a significantly greater proportion of their sessions (21.2 1.5%) than were adult females (N ¼ 84, 15.8 1.3%, Manne Whitney U test: Z ¼ 3.21, P ¼ 0.001). Within each sex, low-ranking adults were also found alone significantly more often than were high-ranking individuals (Spearman rank correlation: rS ¼ 0.77 and 0.85, N ¼ 24 and 18 rank positions, for adult females and immigrant males, respectively, P < 0.00001 for both; Fig. 3b). The study gives percentages showing highest ranking female hyenas are alone about 11% of the the time while lower ranking male and female hyenas may be alone up to 25%-30% of the time. Matriarch hyena lower tendency of being alone and relatively small portion of hyena populations makes it unlikely many one on one encounters with male leopards involve matriarchs IMHO. |

Wow, interesting stuff. Thanks for the correction Reddhole, guess males can potentially be more aggressive than I thought! |

Hey Guys I feel like i have not seen adolescent male spotted hyena of 50 kilograms against powerful male leopard 70 kilograms in this topic. Am I wrong? |

Makes sense. Pre-reproductive spotted hyenas are alone less than adults. About 15% of the time they are alone. Here is paper(see figure 3 a): http://people.mills.edu/jesmith/Smith%20et%20al.%202008_Fission-fusion%20dynamics%20in%20hyaenas.pdf Low-ranking females and males are alone most often.

A matriarch hyena could be likened to a fully mature territorial male leopard (7 year plus). Such leopards make up only a fraction of the total population and this should also be borne in mind. In the following study, fully mature males made up only 8% of the total leopard population and about 28.5% of the adult male (4 year plus) population. From: "Applicability of Age-Based Hunting Regulations for African Leopards 2012" ![]() ![]() As we can see males only reach their physical peak at around 7 years old though they are widely considered adult at age 4 or even 3. Furthermore, unlike some other cats such as cougars which apparently retain the same general proportions (relative head size etc.) regardless of age and sex, male leopards take on more impressive proportions once fully mature. |

Yes, but the interaction on this topic does not seem to me among hyenas not yet reproductive and leopard or so.. I see hyenas have a weight of not less than 65 kilograms, that female with the Sand river male leopard, even larger than large male leopard. But what we are interested is the interaction of individual cases we have, you experts of hyenas don't know if they are male or female or the age in accounts of this specific topic??

We don't. However, based on hyena numbers and percentage of time alone the interactions are most likely to involve males (especially lower ranking males) and the lowest ranking females. Just to quantify this. Let's say there is clan of 50 hyenas. 1 matriarch would constitute 2% of the population. Let's say on average, a matriarch is only half as likely to be alone than other hyenas. This would imply there is only a 1% chance of a matriarch challenging a leopard in a one on one confrontation. Obviously, this is just a rough estimate. However, the point is matriarchs seem less likely to be involved in one on one confrontations than large male leopards. |

And if the clan is 5 hyenas? |

Especially the fact that a hyena has moved alone against a leopard does not mean that necessarily go out alone all the time. Let us assume that a matriarch feel a kill a few dozen feet from her, it may well get away momentarily from the group. |

Well, they can take the risk, because if they get injured by the Leopard, they have other Hyena who can care for them and if it's getting into trouble, it can call them. However, these two, were together: |

Well, that is on low end of clan size range: Across 19 study populations in which all individ- ual members were known for one or more clans, mean clan size was 28.8 hyenas, but this ranged from 3 to 67 hyenas (Holekamp & Dloniak 2010), with the largest clans occurring in the populations of highest density (linear regression: r2= 0.717, P < 0.0001, Fig. 2A). More importantly, spotted hyena leopard interactions are more likely to occur in areas with denser populations of both species which tends to happen when food is plentiful and clan size is large.

This is what a Sabi Sands male leopard does with a hyena![]() This happened today at the Idube reserve. More info will follow.. I still do not know which leopard did this but the resident males are: Kashane, Maxabeni (young leopard but killed a hyena before),Dewane, Xinzele, Xindlevhana (know for maybe killing a giraffe),Mashiabanj.

In any case, no one has explained why the accounts between leopard and hyena, hyenas are seen at least as large as leopards large size (65 - over 70 kilograms), this remains a mystery |

This is quite not very correct, an high density of hyenas should reduce the size and the number of leopards, so interacts would be like zambia, not like in kruger. |
