Zoo Aardvark Welfare: Nocturnal Care and Enrichment

Aardvarks are solitary nocturnal insectivores that present significant husbandry challenges in zoos, requiring specialized diets, reversed lighting, and excavation opportunities.

Key Facts

Aardvarks excavate up to 1 meter of soil per minute using powerful foreclaws
They consume up to 50,000 ants and termites per night in the wild
Aardvarks are entirely nocturnal and rely heavily on scent and hearing, not vision
They are solitary animals with minimal social tolerance outside of breeding
Aardvarks are currently of Least Concern but face pressure from habitat loss and bushmeat hunting

Welfare Considerations

Captive aardvarks require soft substrate deep enough for digging behavior, which is both physically necessary for claw maintenance and psychologically important. Reversed lighting allows daytime visitor access while supporting natural activity cycles. Specialized insectivore diets must replicate the nutritional profile of wild ant and termite prey. Failure to meet these needs results in stereotypic pacing and poor physical condition.

What You Can Do

Support zoos that invest in naturalistic substrate and nocturnal exhibit design for aardvarks
Encourage evaluation of aardvark behavioral indicators including digging frequency and substrate use
Advocate for habitat protection in sub-Saharan Africa that supports wild aardvark populations
