Haig’s Tuco-tuco

Haig’s tuco-tuco (Ctenomys haigi), known regionally as the Patagonian tuco-tuco, is a South American rodent. Like other tuco-tucos it is subterranean and thus not often observed. The “tuc-tuc” call of the males can be heard near burrow sites, especially in early morning. Like most species in the genus Ctenomys, C. haigi are solitary. They have one adult per burrow.

Haig’s tuco-tuco is native to both Argentine and Chilean Patagonia. Its primary habitat is the Patagonian steppes. It is also found in Low Monte and Valdivian temperate rain forests west of South America.
