Cory's shearwater
Strofades (; also called Strofadia, , or Stromphides, ) is a group of two small Greek islands in the Ionian Islands. They lie about south-southeast of the island of Zakynthos. Administratively they are part of the Municipality of Zakynthos. The larger island, Stamfani, has an old fortress/monastery built in 1241. The smaller is Arpia. Both are sparsely vegetated and rocky. There is a strong avian presence on the islands, and hunting is prohibited. Species include Cory's shearwater ("Calonectris diomedea") and migratory passerines. There is also a large spring migration of turtle doves ("Streptopelia turtur").
