I tested four previously published hypotheses that have been used to explain the function of tail flagging in white-tailed deer by comparing the behavior of deer during the approach of a person on foot to that expected under each of the hypotheses. Deer tend to tail flag toward an approaching person and, when they have the opportunity to do so, do not flag toward conspecifics only. Both single deer and deer in groups flag their tails. Deer are more likely to tail flag when they flee at safe… 

Ontogeny and Adaptiveness of Tail-Flagging Behavior in White-Tailed Deer

White-tailed deer use two tactics to avoid predation: freeze behavior to avoid detection, and flight, during which deer frequently flagged their tails, which suggests that the behavior evolved as part of continued and intense doe-fawn interactions.

Tail-Flicking, Tail-Flagging, and Tail Position in Ungulates with Special Reference to Black-Tailed Deer

The confusion in the literature regarding the definition of tail movements is discussed, two behavioral patterns and three tail positions are redefined, and their performance in Columbian black-tailed deer in response to an approaching human is examined.

Why some rails have white tails: the evolution of white undertail plumage and anti-predator signaling

It is found that adaptation to open wetland habitats significantly precedes the evolution of white undertails, whereas gregariousness likely evolved later in some lineages and the inferred order of trait evolution suggests that this plumage characteristic could have been selected primarily for enhancement of an anti-predator signal rather than a social signal for conspecifics.

Do Brown Hares Signal to Foxes

Of a total of 32 sedentary brown hares (Lepus europaeus) approached across open ground by foxes (Vulpes vulpes), 31 reacted when the fox was 50 m or less from them by adopting a bipedal stance

Variation in Vigilance in White-tailed Deer (Odocoileus Virginianus) in Northeastern Kansas

It is concluded that deer exploit loose aggregations to maximize foraging time by decreasing individual vigilance (without increasing risk) and that the trade off between vigilance and foraging intensity changes with maturation.

The Predator Deterrence Function of Primate Alarm Calls

It is concluded that the high alarm call rates to leopards are part of an anti-predator strategy in primates that may have evolved to deter predators that depend on surprise.

Wing-Flashing by Northern Mockingbirds While Foraging and in Response to a Predator Model

It was found that foraging bouts during the reproductive period were more likely to include WF than those during the non-reproductive period, but that there was no significant relationship between WF rate and either strike rate or foraging-success rate.



Evolution of Alarm Signals in Ungulates with Special Reference to White-Tailed Deer

It is suggested that tail flagging in white-tailed deer, and the ungulate rump-patch phenomenon in general, serves as a socially cohesive signal that helps to keep individuals in groups for antipredator benefits.

On the Improbability of Pursuit Invitation Signals in Mammals

Smythe (1970) proposed that, in many mammal species, alarm signals have evolved as a mechanism by which individuals of a prey species try to induce a predator to enter into a chase that has a

The "Pursuit Deterrent" Function of Alarm Signals

This thesis provides evidence that alarm signals act as "pursuit deterrent" signals and is related to that of Smythe (1970), who proposed that the display of the white rump patch in various herbivorous mammals "invited pursuit" from a predator.

Evolutionary studies suggest that behavioral as well as morphological characters are not maintained in a population unless they contribute to the longevity or reproductive proclivity of the possessing organism.

A New Theory of Mammalian Rump Patch Evolution

The rump patch has been selected for because it gives a more positive signal of submission than a behavioral gesture used alone, and as a secondary development it may also function as a warning signal or in reproductive isolation of sympatric species.
