Wallace's Tarsier (Tarsius wallacei)


MORPHOLOGY:
With regards to size, Wallace's tarsier is similar in size to other lowland tarsiers found on Sulawesi (Merker et al., 2010). The head and body lengths of this species average 12 centimeters (Merker et al., 2010). The pelage of this species is mostly mottled yellowish brown in coloration with an off-white ventrum (Merker et al., 2010). The throat is copper colored and above and below the eyes are yellow to copper-colored patches that form a near complete eye ring (Merker et al., 2010). The tail is dark with having a thick and long tail pencil (Merker et al., 2010). There is no sexual dimorphism in terms of body size between the sexes (Merker et al., 2010).

RANGE:
Wallace's tarsier is found on the island of Sulawesi, Indonesia (Merker et al., 2010). There are two populations, a northern one that occurs on the isthmus of Palu west of the village of Tomini to the villages of Ampibabo and Marantale to the south, and a southern one that occurs west of Palu around the village of Uwemanje (Merker et al., 2010).

ECOLOGY:

SOCIAL BEHAVIOR:

VOCAL COMMUNICATION:
duet call: This starts with a one-note introduction by the female, then the female notes are a hook-shaped whistle that begins at 12-13 kHz and descends to 5 kHz in about 0.4 seconds (Merker et al., 2010). The female will emit two notes in rapid succession with a time interval of 0.1 seconds (Merker et al., 2010). The male notes are wideband chevron-shaped chirps (Merker et al., 2010).
