1 hour sound of Puffinus
Puffinus is a genus of seabirds in the order Procellariiformes that contains about 20 small to medium-sized shearwaters. Two other shearwater genera are named: Calonectris, which comprises three or four large shearwaters, and Ardenna with another seven species (formerly often included within Puffinus).
The taxonomy of this group is the cause of much debate, and the number of recognised species varies with the source.
