In the southern part of the island of Terceira, some people claim a German U-boat hid in the waters around the islet during World War II, conducting its attacks from the area.
[1] Azorean writer Vitorino Nemésio, a native of Terceira, referred to the islets as "a estátua da nossa solidão" ("the statue of our solitude") in his 1956 book Corsário das Ilhas (English: Corsair of the Islands).
In 2011 the Ilhéus das Cabras ZPE (Portuguese: Zona de Proteção Especial, or Special Protection Zone in English) was formally integrated into the Nature Park of Terceira.
[5] The islets are located on the southeast coast of Terceira, east of Angra do Heroísmo, and politically part of the civil parish of Porto Judeu.
[1] Difficult human access and rocky cliffs makes this area an ideal location for a significant population of Cory's shearwater (Calonectris borealis) and common tern (Sterna hirundo), which annually migrate through the Azores to nest, in addition to grey heron (Ardea cinerea), sanderling (Calidris alba), Kentish plover (Charadrius alexandrinus), and other marine birds such as seagulls (family Laridae).
[1] The biodiversity and geographical conditions make the area around the Cabras ideal for sub-aquatic activities, including recreational diving and scientific investigations.
