Do hares ever stot?

I thank @lefebvremax and @beartracker for helpful discussion of this topic.

Various species of ruminants stot ( and

This behaviour occurs also in a large-bodied, hare-like rodent, namely Dolichotis ( and and and and

The nature of stotting is basically as follows. The animal:

  • moves exuberantly, expending energy in a conspicuous and inefficient way, and
  • handicaps itself in its locomotion, as if to show off its individual fitness.

Stotting is clearly a form of self-advertisement. However, questions remain of:

  • whether the demonstration is directed towards members of the same species on one hand, or potential predators on the other, and
  • what message is being sent.

As far as I know, no naturalist has previously claimed that any lagomorph stots, at least in the quadrupedal way. The words 'hare' and 'stot' do not seem to appear in the same sentence, anywhere in the biological literature.

What have been frequently mentioned are 'observation leaps' ( and, in which hares in the act of fleeing intersperse their normal gallop with occasional, particularly high bounds.

Nearly all authors seem to have assumed that 'observation leaps' function not as a form of self-advertisement, but rather as a way of maintaining a clear view of the potential predator.

Therefore, in view of the above:
Establishing that Lepus stots in evolutionary convergence with ruminants and Dolichotis would be something new to science.

At present, the evidence for stotting in hares falls into three categories (besides 'observation leaping', part of the function of which remains questionable), as follows:

  • sundry photos and videos suggesting aberrations from the normal gaits of running, often in uncertain circumstances,
  • clear evidence, in a few large-bodied, ecologically extreme species, of bipedal gaits unknown in other mammals but plausibly interpreted as a form of stotting, and
  • fairly unambivalent self-advertisement in one species, which probably constitutes stotting but has not been labelled as such.


The following photos and videos suggest subtle forms of stotting. The contexts are unclear, and in some cases may be courtship and rivalry rather than reactions to the approach of potential predators. It is also possible that hares differ from ruminants and Dolichotis in that the bouncing gait occurs not as the animal initially runs but instead as it slows down from a bout of running.

Lepus californicus: and

Lepus townsendii: and

Lepus timidus:

Lepus europaeus:
Two gaits suggestive of stotting can be seen from about 4 minutes 30 seconds in and from about 1 min 45 sec in
The following show possible stotting: and and and and and and

Lepus does not normally erect its tail in flight. I suspect that stotting in e.g. Lepus europaeus sometimes features both a bouncing action and the swinging of the tail higher than usual (as seen in the first photos in each of and This exposes not just the white underside of the tail (which is only partly exposed in normal fleeing gaits in Lepus) but also a white patch of pelage on the buttocks, which is hardly noticeable in the normal action of fleeing.

BIPEDAL LOCOMOTION IN LARGE-BODIED SPECIES, possibly qualifying as stotting


Only a few species of hares use bipedal gaits when fleeing from potential predators ( It seems reasonable to interpret this as a form of stotting. Lepus arcticus and L. alleni are both unusual for hares by virtue of their large body size and their gregariousness.

In L. arcticus, both hind legs move in synchrony in the bipedal gait. However, the action is different from that in wallabies because the strides are short and rapid, and the body is held upright.

In L. arcticus, there is an additional gait in which only three legs touch the ground (, in what amounts to a self-imposed, running limp.


See Lepus callotis in

This species seems to qualify for stotting in a quadrupedal gait resembling that in ruminants..

Best and Henry (1993) state: "When flushed, L. callotis alternately flashes its white sides while running away from the intruder...Another escape behavior is that of leaping straight upward while extending the hind legs and flashing the white sides. This behavior is seen when the white-sided jackrabbit is startled or alarmed by a predator."

Seemingly relevant is the fact that L. callotis is unusual in its social structure. This species is the only hare known to occur in pairs, with an obvious pair-bond.


Much remains to be documented and interpreted with respect to possible stotting in hares.

For example, a detailed review of Lepus timidus ( and makes no mention of any gaits, despite the wide distribution of this species and its close relationship to L. arcticus.

Not only 'observation leaping' but also bipedal standing at the approach of potential predators ( and, when conducted in the open (, may make more sense as demonstrations of individual fitness than as ways of keeping a potential pursuer in sight.

Regardless of the poor coverage in the past, what is already clear is the diversity of gaits (plus postures such as demonstrative, bipedal standing) listed above as candidates for stotting.

No species of Lepus stots as frequently/predictably as do certain gazelles, deer, and Dolichotis. However, where hares seem to excel is in the variety of gaits that are candidates for stotting within a single genus. I know of no genus of hoofed mammal or rodent in which such a diversity of potentially self-advertising forms of locomotion occurs.
