Summary
Foraging
Animal
may involve complex
relationships among several
species.
Some animals, especially birds in the
family are capable of tremendous
memory to remember the locations of food
caches.
According to the
foraging
theory,
rate with the most
profitable
food item determines an animal's choice of
food.
The
value
theorem predicts how much
time
a forager should stay in a given
patch.
Foraging for energy-rich foods may need to be balanced against the need to consume energy-poor food that provide
nutrients
such as
; this need can be estimated by
programming
models.
Hungry foragers should be
prone,
that is, willing to assume greater variance (risk) in food
intake.
Less hungry individuals tend to be more risk
averse.
Learning
how and on what to forage may involve innovations;
size
often correlates with the frequency of such foraging innovations.
The
theory of learning predicts that a reward obtained by
effort
is valued more than the same reward obtained with
effort.
In group-living species,
social
interactions within a group can impact foraging behavior.
Cooperative
in wild
dogs
and
chimpanzees
increases foraging success for the group.
Scavengers benefit from
learning,
though
may
inhibit
learning.
of the foraging behavior of
others
may alter an individual's food choice.
Learning about foraging environments may be obtained from
information.
Foraging behavior is often controlled by
products such as the
period
gene and
hormones.
