Honeybees use the
waggle dance to communicate the location of a patch of flowers suitable for foraging. The degree of displacement in this example remains limited when compared to human language. A bee can only communicate the location of the most recent food source it has visited. It cannot communicate an idea about a food source at a specific point in the past, nor can it speculate about food sources in the future. In addition, displacement in the waggle dance is restricted by the language's lack of creativity and productivity. The bees can express direction and distance, but it has been experimentally determined that they lack a sign for "above". It is also doubtful that bees can communicate about non-existent nectar for the purpose of deception. Consequently, in honeybee communication, the potential for displacement is limited, but it is there insofar as they have the ability to communicate about something not currently present (i.e., something that is spatially removed).
Ants have been observed sending out scouts to patrol for food items, and coming back for other workers if the food found is too large to bring to the nest by the finder alone; for example, a dead caterpillar that is too heavy. This again would involve displacement by communicating outside of the here and now. Recruitment has also been observed by the African
Weaver Ant Oecophylla longinoda for the purpose of communicating new food sources, emigration to new sites, and for defense against intruders. Researchers have described no less than five distinct systems to fulfill these functions in this species. The ants communicate using a system composed of olfactory or scent clues from several glands together with body movements. The animals will use antennation, body jerking, and mouth-opening, and will combine these clues with the application of the scent trails or scent release to pass on information regarding resources or intruders.
Ravens (
Corvus corax) have been observed to recruit other ravens to large feeding sites, such as to the carcass of an animal. However, their motivation for recruiting appears less obvious, and the specifics of their communication system are more elusive. Still, it has been documented that ravens must have such a system, as their patterns of gathering at sites clearly indicate that they must have been informed of the presence of the resource. It is believed that non-mated ravens call in a group of other non-mated birds to be able to feed and not get chased away by mated territorial pairs of established ravens. In addition to honeybees, ants, and ravens, the
Greater Honeyguide (Indicator indicator) achieves displacement when it signals to humans the location of distant honeybee colonies. This fascinating mutualistic relationship between people and a wild bird, and the communicative system underlying the partnership, has been studied by anthropologists and ornithologists. ==Importance in evolution of language==
