Suckling and allosuckling behavior in wild giraffe (Giraffa camelopardalis tippelskirchi)
Allosuckling has been reported in many mammalian species. In giraffe, allosuckling has been observed in captivity, and the milk theft hypothesis with reciprocity is regarded as the likeliest explanation for this behavior. However, reports of such behavior in the wild remain sparse to non-existent. Here, we studied the suckling and allosuckling behaviors of three nursing […]
Stealing milk by young and reciprocal mothers: high incidence of allonursing in giraffes, Giraffa camelopardalis
Allonursing, the nursing of nonfilial offspring, has been reported in a number of mammalian species; however, very few studies have investigated more than three hypotheses. The aim of our study was to investigate seven hypotheses explaining allonursing in captive giraffes. During 2007-2011, we observed 24 females and 37 calves in four zoological gardens in the […]
