Daten zur Schlafdauer in der Herde Asiatischer Elefanten (Elephas maximus) im Zoologischen Garten Berlin

Due to the night observations during the gravidity of the Asian Elephant “Pang Pha” in 2005 it was possible to receive data on the sleeping behavior of 1.3 Asian elephants (Elephas maximus) at Berlin Zoological Garden. These elephants were the breeding bull “Victor” (born 22.10.1993 at Zoological Center Ramat Gan), “Pang Pha” (born 1987 in Thailand), “Drumbo” (born 1970) and “Iyoti” (born 1974 in India). Elephant “Pang Pha” slept only one and a half hour, whereas the two older cows lay nearly four hours. The bull lay longest.
