Nice to see this Ted. Not an easy capture from a boat!
The feature other than plumage that gives the bird away as a Red Phalarope (Grey Phalarope in UK) is the relatively stout, thick bill compared to its cousins.
This looks like a male, which is duller than the female. Phalaropes as many of you may know show what is called reversed sexual dimorphism- the female is larger and brighter coloured than the male. On what date was the image created Ted?- this will determine to a large degree further interpretation of the image.
