|Squacco Heron (Ardeola ralloides)|
|Coto Doñana, Spain
These birds are in their summer plumage when they show blue rather than yellow on their bills.
Squacco Herons look generally brown at rest but transform into almost white-looking birds when in flight.
|They are migratory, spending the Northern winter in sub-Saharan Africa, arriving in Europe in April/May returning to Africa from August to November|
