Behavior
The golden-crowned sifaka is primarily active during the day (diurnal), but researchers have witnessed activity in the early morning and evening (crepuscular) during the rainy season (November through April). In captivity, it has been observed feeding at night, unlike captive Verreaux's sifakas. It travels between 461.7 and 1,077 m (1,515 and 3,530 ft) per day, an intermediate range compared to other sifakas of the eastern forests. The golden-crowned sifaka can be observed feeding and resting higher in the canopy during the dry season (May through October). It sleeps in the taller trees (the emergent layer) of the forest at night.
When stressed, the golden-crowned sifaka emits grunting vocalizations as well as repeated "churrs" that escalate into a high-amplitude "whinney." Its ground predator alarm call, which sounds like "shē-fäk", closely resembles that of Verreaux's sifaka. It also emits mobbing alarm calls in response to birds of prey.

Famous quotes containing the word behavior:
“No one is without Christianity, if we agree on what we mean by that word. It is every individual’s individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol—cross or crescent or whatever—that symbol is man’s reminder of his duty inside the human race.”
—William Faulkner (1897–1962)
“School success is not predicted by a child’s fund of facts or a precocious ability to read as much as by emotional and social measures; being self-assured and interested: knowing what kind of behavior is expected and how to rein in the impulse to misbehave; being able to wait, to follow directions, and to turn to teachers for help; and expressing needs while getting along with other children.”
—Daniel Goleman (20th century)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
