Up close! Tiger devours unfertilized swan egg

Zookeepers offer the Sumatran tigers at Royal Burgers' Zoo (Arnhem, The Netherlands) an unfertilized black swan egg as a form of behavioral enrichment. Thanks to a GoPro attached nearby the egg, the footage obtained provides for an up close acquaintance with these majestic animals.

Unfertilized swan eggs

At Royal Burgers' Zoo two black swans share an enclosure with swamp wallabies. Since both animals are female, the eggs they produce are unfertilized. Sometimes zookeepers use these eggs as behavioral enrichment for other species, such as tigers, binturongs, or several species of monkeys. The eggs both serve as behavioral enrichment as well as an addition to the balanced natural diets zoo animals receive every day.

Successful breeder of Sumatran tigers

Burgers' Zoo has been very successfull in breeding Sumatran tigers last years. Two times in a row, twins were born and raised by their parents in a natural way. The four young-adult tigers have already moved to several other European zoos, participating in the European breeding programme for Sumatran tigers.
