Kleptoparasitism
Kleptoparasitism (originally spelt clepto-parasitism,
Strategy
Kleptoparasitism is a feeding strategy where one animal deliberately steals food from another. This may be intraspecific, involving stealing from members of the same species, or interspecific, from members of other species.[3][4] The term denotes a form of parasitism involving theft, from Greek κλέπτω (kléptō, 'steal').[5] The strategy has been widely studied in birds; in four families, all seabirds, the Fregatidae, Chionididae, Stercoraridae, and Laridae, it occurs in more than a quarter of the species.[6][4]
Such a strategy should only be followed if it is evolutionarily stable, meaning that it offers a selective advantage to individuals that practise it. Kleptoparasitism costs time and energy which could otherwise be spent directly on feeding, so this cost must be outweighed by the benefit in energy gained from the stolen food. Mathematical modelling suggests that when food is abundant, ordinary feeding is the best strategy; when food abundance falls below a critical level, kleptoparasitism suddenly becomes advantageous, and aggressive interactions become common. Similarly, when potential victims are rare or widely dispersed, the time needed to find them may not be justified by the food that might be stolen from them, resulting in frequency-dependent selection.[3][6]

Others are dubbed kleptoparasitoids, namely parasitoids that select hosts that have been parasitized by another female. Kleptoparasitoids may make use of the punctures made by previous parasitoids on their hosts; may follow the trails or traces left by parasitoids to locate hosts; or use hosts already weakened by other parasitoids.[15]

Dung beetles
Scarab dung beetles relocate large amounts of vertebrate dung, rolling balls of the material to their nests for their larvae to feed on. Several smaller species of dung beetle do not gather dung themselves but take it from the nests of larger species. For example, species of Onthophagus enter dung-balls while Scarabeus beetles are making them.[19]
True bugs
Many semiaquatic bugs (Heteroptera) are kleptoparasitic on their own species. In one study, whenever the bug Velia caprai (water cricket) took prey heavier than 7.9 g, other bugs of the same species joined it and successfully ate parts of the prey.[20]
Spiders
Kleptoparasitic spiders, which steal or feed on prey captured by other spiders, are known to occur in five families:
- Theridiidae (Argyrodes species)
- Dictynidae (Archaeodictyna ulova)
- )
- Symphytognathidae (Curimagua bayano)
- Mysmenidae (Isela okuncana, Kilifia inquilina, and Mysmenopsis species).[21]
Vertebrates
Birds
A few bird species are specialist kleptoparasites, while many others are opportunistic.
During
Gulls are both perpetrators and victims of opportunistic kleptoparasitism, particularly during the breeding season. While the victim is most often another member of the same species, other (principally smaller) gulls and terns can also be targeted. In the Americas, as brown pelicans surface and empty the water from their bills, they sometimes have their food stolen by Heermann's gulls and laughing gulls, which lurk nearby and grab escaping food items.[28] Great black-backed gulls are skilled kleptoparasites, stealing from other gulls and from raptors. Several species of gull steal food from humans, for example takeaway food at seaside resorts.[29]

Mammals
The relationship between spotted hyenas and lions, in which each species steals the other's kills,[30] is a form of kleptoparasitism.[20] Cheetahs are common targets. Bears, coyotes and wolves are very opportunistic and all have this behavior. Crab-eating macaques have also exhibited kleptoparasitic behaviors. All hyena species engage in this behavior when they can, as do jackals.[31] Human hunters may commonly take the remains of fresh kills from other carnivores, such as lions and Eurasian lynx.[32][33][34] Risso's dolphins have been observed charging "head-on" at sperm whales, causing them to open their mouths; it has been suggested that the observed harassment results in some regurgitation, and that the food is then eaten by the Risso's dolphins. The behaviour is rare and may be opportunistic.[35]

A little later, hyenas have driven off the cheetah and are feeding.
