Nosorožci tuponosí (Ceratotherium simum) a Cottonovi (Ceratotherium cottoni) mají nejvyvinutější sociální systém ze všech druhů nosorožců, přesto toho o jejich sociálním chování a především komunikaci bylo donedávna známo jen málo. V článku jsou popisovány výsledky čtyř recentních studií, které se zabývaly sociálním chováním a vokální a olfaktorickou komunikací obou druhů v rezervacích v Jihoafrické republice i v zoologických zahradách.

The Northern and Southern White Rhinos (Ceratotherium cottoni and C. simum) have the most developed social system among all the rhinoceros species. Until recently, little has been known about their communication and social behaviour. This paper presents the results of four recent studies involving research into the social behaviour and vocal and olfactory communication of these species both in the wildlife reserves in South Africa and in zoological gardens.
