The Krause catalogue says the bird pictured on this coin is a Moor hen, meaning a Common moorhen which is found in Norway. However, it looks nothing like that bird, and I can find no other references to it being that bird (other than people quoting what Krause states).
The bird on this coin is a Black Grouse, which is also common in Norway. It is found in boglands near boreal forests. The male Black Grouse has a distinctive lyre-shaped tail, which is clearly pictured on the coin.
This coin was minted from 1958 to 1972, when 2-øre coins were discontinued.
