Infrasound and low frequency vocalizations from the giraffe
The giraffe, a savanna ungulate, possessing limited auditory vocalizations, was found to produce infrasound. Recordings were made of 11 Giraffe (Giraffe camelonardalis reticulata), at the North Carolina Zoological Park in Asheboro, North Carolina and the Riverbanks Zoo and Botanical Garden in Columbia, South Carolina. A portable system (7Hz – 22 kHz) was used to record […]
Nocturnal “humming” vocalizations: adding a piece to the puzzle of giraffe vocal communication
Background: Recent research reveals that giraffes (Giraffa camelopardalis sp.) exhibit a socially structured, fission– fusion system. In other species possessing this kind of society, information exchange is important and vocal communication is usually well developed. But is this true for giraffes? Giraffes are known to produce sounds, but there is no evidence that they use […]
Giraffe Helmholtz resonance
Introduction The following acoustical assessment documents infrasonic vocalizations that are produced by giraffe and demonstrates these vocalizations occur in social contexts. It also proposes that Helmholtz resonance is used to produce such vocalizations. Giraffes are large ruminant browsers that live in sub-Saharan Africa. Giraffe females and young are usually sighted in small groups whose composition […]
