It appeared the species was still hanging on, if only by the slimmest of threads. Even though later searches between 2004 and 2006 failed to turn up anything other than one claim of a single vocalization, the IUCN listed the Miss Waldron’s monkey as critically endangered and possibly extinct. The species simply did not yet meet the criteria for extinction. If Miss Waldron’s monkey still survives somewhere, it may be in Ehy Forest of eastern Ivory Coast. It was near here, on the edge of a large lagoon surrounded by villages, that scientist Scott McGraw—who had been searching for years in vain for the elusive animal—found that aforementioned skin of a Miss Waldron’s monkey.
On the upside, a hitherto unknown population of greater bamboo lemurs was recently confirmed in the Torotorofotsy region of the country, about 400 kilometres north of the animal’s previously known range. Several family groups totalling up to 60 animals inhabit this area, which borders an important protected wetland and a national park. One family unit appears to live within the wetland itself. As encouraging as this new find is, the other populations to the south are declining. Most greater bamboo lemurs live outside protected areas, so establishing formal reserves for them is a priority.

They landed in front of me as grey fog gave way to brilliant blue skies and revealed the surreal purples, yellows, and browns of the caldera.
