and extend nearly the length of the body. The dorsum and sides
of the head are green; the flanks and hidden surfaces of the thighs
are reddish brown with cream spots bordered by black. The throat,

Ecology
Habitat:
arboreal , found in terre firme forest, secondary
forest and clearings.
Niche:
carnivorous: prey includes insects and any small creatures it
can catch.
Life History:
Nocturnal and highly arboreal, P. bicolor lives in primary and
secondary forest. Males call from branches as high as 8 or more
meters above the ground and descending to 1-2 m above ponds to
mate; the call is a loud "cluck" followed by several
short, lower-pitched notes. Skin secretions of adult frogs contain
a variety of vasoactive and opiod peptides; dried secretions mixed
with human saliva are introduced into the blood stream through
deliberate breaks in the skin by Panoan-speaking groups of Amazon
indians, such as the Mayoruna, who experience pain and gastric
distress prior to feeling energized and refreshed.
Status:
Uncommon. In the Reserva Comunal Tamshiyacu-Tahuayo area it is
found in primary forest along the Quebrada Blanco.
