Edinburgh Zoo welcomes second Critically Endangered Sumatran tiger

Posted 28 May 2026

The Royal Zoological Society of Scotland’s (RZSS) Edinburgh Zoo has welcomed Sialang, a Critically Endangered Sumatran tiger, as part of a European breeding programme to help boost the numbers of this rare tiger subspecies. The nine-year-old tiger moved to the capital from Twycross Zoo and is settling into his new home well.

Keepers at the wildlife conservation charity hope Sialang will have cubs with visitor-favourite, Dharma. The pair will slowly be introduced to each other in the coming months.
