Green Frog

Lithobates clamitans
Ranidae
Unexpected nowFrog
Occasional. Never better than a coin toss here in any week of the year.
Field marks
A green or bronze frog with a bright green upper lip and two ridges running down the back from the eyes.
Male & female
Males have a yellow throat and eardrums larger than the eye.
Voice
A single explosive 'gunk', exactly like plucking a loose banjo string, sometimes repeated.
Diet
Insects, spiders, snails, small fish.
Habitat
Pond and stream edges in eastern North America; introduced in a few spots in Washington.
Nesting
Egg masses in shallow water in early summer.
Size
2–4 in long, 1–3 oz: a stick of butter with legs and opinions.

Not a native of the Northwest; established populations here are few and local. A 'Green Frog' detection is more likely a bullfrog or a stray noise.
