The birds in Sarek include a number of owls, such as the Ural owl, and woodpeckers, particularly the Eurasian three-toed woodpecker. The grey-headed chickadee is also very common, as are the fieldfare, the song thrush and the redwing. Reptiles and amphibians, such as the viviparous lizard, the common frog and the common European viper, are mostly found in the forests. The vipers of the Rittak region frequently reach remarkable sizes.
