The American White Pelican or Rough-billed Pelican (Pelecanus erythrorhynchos) is a large aquatic bird from the order Pelecaniformes. It breeds in interior North America, moving south and to the coasts, up to Central America, in winter.
The scientific name means "red-billed pelican", from the Latin term for a pelican, Pelecanus, and erythrorhynchos, derived from the Ancient Greek words erythros ("red") + rhynchos ("bill").
What a surprise when walking through St James Park in London to see this species at home on the lake. This one was feeding from the reeds and collected some on the beak and neck, this, together with the droplets falling from the end of it's beak adds an extra feature to the image.
