Taxonomy & Occurrence

Eulemur sanfordi is a monotypic species. Its geographic range is restricted to northern Madagascar, from the Montagne des Français near Diego Suarez as far south as the Manambato River, which marks the southernmost extremity of its range. It is found in a number of accessible protected areas, including Montagne d'Ambre and Ankarana national parks, the Analamerana Special Reserve [1] and in the forests of the Daraina region such as the Loky-Manambato Protected Area [2].

Seeing this Species

 

The only other member of the genus sympatric with the Sanford's Brown Lemur is Crowned Lemur (Eulemur coronatus), although the two are easy to distinguish. The Sanford's Brown Lemur is a medium-sized lemur, pale brown in colour, with a black face and orange eyes. This species is sexually dimorphic - the males are characterised by their stark white ear tufts and mane-like beard, of which the female is lacking. This species is cathemeral, i.e. active both day and night and group size can number up to 15 [3], meaning they can be noisy and relatively easy to locate.

 

While this species, especially the female, may be difficult for the inexperienced primate-watcher to distinguish from other members of the Eulemur genus, its limited range and the lack of overlapping similar species makes identification more certain in the field.

 

Montagne d'Ambre National Park, Antsiranana Province, Madagascar 

This national park is easily accessible by car from Diego Suarez (approximately 30km). While a day-trip is possible, it is recommended to stay at one of the comfortable lodgings just outside the Park, which would enable you to do some night walks in the hope of seeing some of the nocturnal primate species in the area.

 

This national park is very visitor-friendly, with broad, open trails taking visitors to waterfalls and botanical gardens. There are some truly excellent guides in Montagne d'Ambre National Park and you may engage them from the park office. The guides are well-versed in the likely hangouts of this species.

 

Although this is a cathemeral species, you are far more likely to see it during daylight hours. Some groups appear well-habituated to human presence, meaning you can potentially get an undisturbed and close look at this beautiful lemur.
