the collection was downsized considerably ( ) the collection is nowhere near the level it used to be.
I agree with that.
I won't compare the current collection with that of the early nineties, when I first visited the zoo. Tasmanian devils, a large collection of cats, multiple species of rare caprine and ovibovine ungulates, a great collection nocturnal mammals... but that was a different zoo, with beside a few Asian exhibits mostly old style houses and enclosures.
Compared to ten years ago, around the time that Artica, the Giraffe House and the "Crocodile River" were opened, the collection is significantly downsized. A couple of years ago I was very disappointed when I visited Blijdorp after some years and so many animals were no longer kept. Next to the losses due to the restyling the Riviera Hall, Blijdorp lost quite a few mammals in the last decade, including several rarities: echidna, agile wallaby, onager, Vietnamese sika deer, lowland anoa, Sichuan takin, klipspringer, sea otter, rusty-spotted and Asian golden cat, jaguarundi, desert hedgehog, variegated rock squirrel and bamboo lemur, among others.
However, in recent years the level is going up again with the arrival of species like Balabac mouse deer, slender loris and elephant-shrew.
