This is an adult with orange goggles. Also known as the Rock Shag this species is sometimes placed in
the genus Stictocarbo or Leucocarbo. Some individuals show a distinct white spot on the face and/or white throat
patch which may vary seasonally. Here the face spot is very faint. This is normally a cliff-nesting species, but
a pair appeared to be occupying a nest site on the stern of a nearby derelict boat. They were nesting in the exact
same place when I visited 6 February 2015. Canon PowerShot SX50 HSReferences:
