Gallinule, Purple (Provincial Rarety)
-Porphyrula martinica (Linnaeus)
Adults somewhat similar to Common Moorhen (next species), but head, neck, and breast deep purple (looks black at distance), back and wing coverts glossy olive-green, under tail coverts all white. Frontal shield bluish. Autumn immatures have no purple on them; the head, neck and breast being brownish, becoming whitish on throat and abdomen, but the upper body showing at least some olive green. Adults are unmistakable. Immatures differ from immature Common Moorhens in having more greenish colour of upper body, more oval-shaped (less elongated) nostrils, no black (all white) in under tail coverts, middle toe not longer than tarsus. Lack of scallops on toes separates them from coots.
