Pacific Treefrog / Rainette du Pacifique
The Pacific Treefrog has rough skin of various colours and patterns. It is distinguished
from other treefrogs by a dark brown or black line across the face that runs horizontally
through each eye. It has large toe pads which help it climb and often has a dark triangle
between the eyes. Adults may reach 5 cm.
is a repeated series of two short high pitched notes. The first note is shorter,
higher and raspier than the second so that the call sounds syncopated.
Although the Boreal Chorus Frog is found in
northeastern British Columbia, the Pacific Treefrog is the only treefrog found in the
southern part of the province. The Boreal Chorus Frog differs in having three dark stripes
down its back. The Wood Frog also has a dark
line through the eye, however it also has prominent
dorsolateral ridges down the back and
does not have enlarged toe pads.
In Canada, the Pacific Treefrog is found only in British Columbia. It is found on the
southern mainland and throughout Vancouver Island. It has been transplanted to Graham
Island and the Queen Charlotte Islands. Southward it is found through the western United
States and into Mexico.
The Pacific Treefrog lives on the ground among vines, shrubs and grasses, near water.
Clusters of 20-50 eggs are laid in the late winter and early spring and metamorphosis is
complete within a couple months.
Pacific Treefrogs can change colour rapidly to more closely match their background. A green
treefrog will stay green but change from an almost blackish green against a dark background
to the most pale of greens against a bright background.
There is no evidence of decline in this species.
