The difficult access and rocky cliffs makes this area an ideal location for a significant population of Cory's Shearwater (Calonectris diomedea borealis) and the Common tern (Sterna hirundo), that annually migrate through the Azores to nest, in addition to Capped Heron (Arrfea cinerea), the Sanderling (Calidris alba), the Kentish Plover (Charadrius alexandrinus) and other marine birds such as Seagulls.
The dominant faunal feature of the island - during the summer months at least - is the active Common Tern (Sterna hirundo) colony spread across the flatter areas of the island that are not taken over by bittersweet (Celastrus) or common reed (Phragmites australis).
