Outline

Intro

  • Omnivorous, mostly frugivorous, occasionally insects
  • Opportunistic and generalist foraging behavior[4]
  • forage together[5]
  • They prefer some fruits over others, however fruit abundance and production influence their diet more than preference. [4]
  • In times of scarcity, fruit consumption decreases and arthropod and leaf consumption increases

Body

  • Seem to prefer fruits form large trees, probably because of lager crop size[4]
  • Choose fruits from species that have clumped distribution, most likely to reduce energy spent getting to another fruit patch[4]
  • Females with offspring are more efficient foragers than adult males[5]
  • juveniles tend to eat more arthropods, this seems to be because they are displaced from the fruit patches during times of feeding by the adult males and females with dependents[5]
  • Females with dependents tend to eat more leaves, thought to be for increased protein ingestion for milk production[3]
  • Spend a large amount of time eating and moving in the pursuit if food, covering about 2 km per day[5]
  • Fruits typically eaten have a tough leathery hide with 1 or 2 large seeds[5]
  • Tend to eat fruits lower in fat and higher in sugar and water[5]
  • Seem to spend most of their feeding time on species Fabaceae, Moraceae, Convolvulaceae, and Sapotaceae. Representing about 50 % of consumption time[3]

Rough Draft

Diet

The brown woolly monkey like all wooly monkeys is omnivorous, but mainly frugivorous. While they prefer certain fruits, such as fruits belonging to the Moraceae (fig) family, fruit abundance and production influence their diet more than preference(4). As such, during periods of scarcity fruit consumption tends to decrease and leaf and insect consumption increases. Their favored fruits include fruits from the Fabaceae (Legume), Moraceae (fig), Convolvulaceae, and Sapotaceae families, representing roughly 50% of consumption time.(3) Females with dependents tend to eat more leaves then males do, most likely because the leaves contain more protein, helping the female produce more milk(3). Juvenile woolly monkeys are shown to eat more arthropods then other members of the group because they are typically displaced from the fruit patch during times of feeding(5).

Foraging Behavior

The brown woolly monkey displays generalist and opportunistic foraging behavior,(4) spending a large amount of time eating and moving in the pursuit of food, covering roughly 2km per day.(5) They tend to prefer fruit species that exhibit a clumped fruit distribution, most likely to reduce the energy spent traveling between fruit patches.(4) They also tend to gravitate towards fruits produced by large trees because they tend to produce a larger crop size.(4) Females with offspring were observed to be more efficient foragers than juveniles and adult males.(5) During feeding times, juveniles are at the bottom of the hierarchy, they are typically displaced by the adult males, and females with offspring.(5)

Final Draft

Diet

The brown woolly monkey like all wooly monkeys is omnivorous, but mainly frugivorous. Their diet consist mainly of fruits containing 1 or 2 large seeds, and fruits that are lower in fat and higher in sugar and water[5]. While they prefer certain fruits, such as fruits from the Fabaceae (Legume), Moraceae (fig), Convolvulaceae, and Sapotaceae families, which represents roughly 50% of consumption time[3]; fruit abundance and production influence their diet more than preference[4]. As such, during periods of scarcity, fruit consumption tends to decrease and leaf and insect consumption increases. Females with dependents tend to eat more leaves, most likely because the leaves contain more protein, helping the female produce more milk;[3] while juvenile woolly monkeys are shown to eat more arthropods then other members of the group[5].

Foraging Behavior

The brown woolly monkey displays generalist and opportunistic foraging behavior,[4] spending a large amount of time eating and moving in the pursuit of food, covering roughly 2km per day.[5] They tend to prefer fruit species that exhibit a clumped fruit distribution, and fruits produced by large trees because they tend to produce a larger crop size and reduce the energy spent traveling between fruit patches.[4] Females with offspring were observed to be more efficient foragers than juveniles and adult males. Inter-group competition during feeding times causes the juveniles to be displaced by the adult males, and females with offspring resulting in an increase in feeding on arthropods and leaves.[5]
