Pickerel Frog (Rana palustris)
The pickerel frog
is a medium-sized ranid (true frog) that can be identified by its
angular brown spots, which often
run in two rows along its back. It also has a light line running along
the upper lip and a bright yellow groin area. The general appearance and
the call of the pickerel frog are very similar to the northern
leopard frog (Rana pipiens pipiens). Northern leopard frogs
usually have light-bordered circular spots and lack the yellow in the
groin. The call
of the pickerel frog is low, snore-like croak, similar to the northern
leopard frog call, but shorter and with less carrying power. Pickerel
frogs are known to sometimes call underwater.
