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").
This photograph was taken on the lake in St James Park, London. It was rather dark in this corner but that has worked for this photograph, creating a contrast isolating the bird from the background and created a reflection without any glare. The day was overcast and this has provided a diffuse light to give detail to the feathers.
