Western Swamphen (Porphyrio porphyrio)

                                            Western Swamphen (Porphyrio porphyrioat Laguna Navaseca, Spain - April 2016

Local Names (Spain): Calamón 
OTHER NAMES: Purple Gallinule, European Swamphen, Western Swamphen
Weight: 725-870g
Length: 38-50cm
Wingspan: 90-100cm
NO UK STATUS IUCN Red List: Least Concern*

A huge, distinctively coloured rail which in Europe is almost entirely found only in Iberia, with a good look at this species, it's unmistakable with it's indigo plumage and bright red beak and legs.  It is however, impressively secretive species for it's bulk, only emerging briefly.  It's also part way through a taxonomic split that makes it's identity a bit more elaborate.  Originally regarded as a single species - the Purple Gallinule/Purple Swamphen across it's range, the European/North African population is now though to represent the earliest divergent lineage of a species that divided by successive waves of expansion with enough gap in between to create new species each time.  My main feeling on this matter is that really the Western Swamphen is far too dry a name for a huge dopey looking purple bird, and thus it's a shame to lose the name Purple Swamphen.
