The European Shag (Gulosus aristotelis) is of the cormorant family Phalacrocoracidae which is in the genus Gulosus. It occurs in northern and western Europe, the Mediterranean Basin, parts of North Africa as well as parts of the Black Sea Coast. This species breeds in colonies on coastal rocky cliffs and on offshore islands. Can easily be confused with Greater Cormorant (Phalacrocorax carbo) but unlike that species, it is very rarely found inland on lakes or rivers.

  

Three subspecies are generally recognised :

• G. a. aristotelis – occurs in northwestern European Atlantic Ocean coasts
• G. a. desmarestii – occurs in the Mediterranean Basin and Black Sea coasts
• G. a. riggenbachi – occurs in northwestern African coasts

The Little Egret (Egretta garzetta) is a small member of the heron family Ardeidae which includes Bitterns, Egrets and Herons. It is found in the temperate parts of Eurasia and Africa as well as Australia and New Zealand. Over the last 60 years or so this species has greatly expanded its range including recolonising its former breeding areas in Northern Europe, as well as Ireland. It first bred in the Caribbean in the mid 1990’s and is increasingly being recorded along the North American eastern seaboard.
