Butaan are Obligate Frugivores! Print E-mail
ImageAn obligate frugivore is an animal whose diet throughout its range consist largely of fruit. Other obligate frugivores in the Philippines include flying foxes, hornbills and other birds. The butaan is much larger than any other obligate frugivore in the Philippines and had a much more restricted diet; on Polillo the diet of adult butaan consists almost entirely of eight species of fruits and two species of snails.

 
 

 

About Mampam
Bye Bye Butaan

Butaan start to visit fruiting trees before they are large enough to swallow the fruits. They make repeat journeys to trees, perhaps to reinforce memory of the position of the tree. If the youngster survives it may continue to use this tree for many decades. Fruiting trees like this are a vital resource for entire populations of butaan. Learn more >

The Butaan Project - Foraging behaviour

butaan7.jpgWe use feces to investigate diet and activity areas of butaan. In total we have examined more than 1500 samples, possibly the largest ever collected for a single population of reptiles.  Butaan and their relatives are huge specialised frugivores, much bigger than any other specialised frugivorous animal in  the Philippines. They need a constant supply of fruit but lack the wings that allow other frugivores to forage in different forest fragments. Large and immobile, the butaan depends on a very narrow range of foods.
