The sound of a primal forest in Transylvania

It’s a calm spring morning at a forested valley in the mountains of Transylvania. A variety of birds compete for space in the sound spectrum, their calls reverberating through the foliage. Common species like Chiffchaff, Song Thrush and Robin can be heard constantly, while others like Cuckoo, Green Woodpecker or Black Woodpecker only call now and then. Very occasionally, guard dogs from a nearby shepherd can be heard way in the distance.
