If a thriving frog population indicates a healthy ecosystem, then Norwegian forests and mountains are doing well. It's hard to miss these active amphibians on our hikes. So far, we have seen at least four distinct varieties.
1)The first frog is the largest and the body measures at least 5-6 inches long. Round circles are clearly visible beside the eyes and noticable stripes appear along the legs. The coloring ranges between orange, yellowish, and olive tones.
2) We found this toad among sheep droppings on steep hillsides where it blends in easily. Notice the wider body, distinct bumps on the back, and the prominent, oblong, puffy patches just behind the eyes. It moves slower than the frogs, perhaps because of its' short and stubby arms and legs. It measure about 4 inches long and 3.5 inches wide.
3)Norwegian frogs come in all sizes including this minute species, less than 1.5 inches long. Just compare it to the blueberry in the upper right hand corner of the photo. Like it's larger cousins, it has a strong dark markings under the eyes.
4) This last frog has the same dark patch under the eyes. You can also see white coloring on the throat, a black line down the body and strong stripes on the legs. It appeared to be about 4 inches long.
