London Zoo begins its annual stocktake

It’s that time of the year where animals at ZSL London Zoo get ready for a head count as part of the annual stocktake.

A requirement of the zoo’s licence, the counting takes keepers a week to complete and all of the information is added to the International Species Information System (ISIS), where it’s used to manage the international breeding programmes for endangered animals.

Among other rare and endangered species are six Philippine crocodiles which were the first of their kind to hatch in the UK in June and nine Humboldt penguin chicks – which were a cause for celebration at Penguin Beach.

Some animals prove harder to count than others, so the zookeepers are resorting to innovative methods such as photographing fish tanks, to make sure every individual is accounted for.
