P. diadema is thought to traverse the greatest daily path distance relative to other members of its family in its patrolling and foraging, attaining a typical travel distance in excess of 1.6 kilometres (one mile) per day. Milne-Edwards' sifaka has the southern-most range of the diademed sifakas. Animal Conservation. The range of P. candidus extends into montane rainforest. Recently, since 2007, the silky sifaka has been considered its own species based on distinct morphological and molecular data compared to the diademed sifaka.

Its entire coat is moderately long, silky and luxuriant. For a large lemur, the diademed sifaka is rather athletic, being capable of lateral aerial propulsion of up to 30 kilometers per hour, a result of muscular leg thrusting action pushing off from a vertical tree trunk. This threat is also present even within designated national parks, which are sufficiently distant from the center of government, that enforcement of existing national laws protecting P. diadema habitat is problematic.
