im trying to figure it out from my iphone

any white on the wing? that would be a good clue

American Black Duck has darker appearance, little buffy edging or internal markings on the body feathers, a purplish speculum without white borders, and lacks a black spot at the base of the bill at the gape.



The adult Mottled Duck is 44�61 cm (17�24 in) long from head to tail. It has a dark body, lighter head and neck, orange legs and dark eyes. Both sexes have a shiny green-blue speculum (wing patch), which is not bordered with white as with the Mallard. Males and females are similar, but the male's bill is bright yellow, whereas the female's is deep to pale orange, occasionally lined with black splotches around the edges and near the base.

if any there is like a speck under there blue

Those are mottled. You can tell by the distinct mottling on the feathers.

Mount worthy!

Need to see the feathers in the speculum.

Mottled

Mottled .....

I agree you have Mottled. Here are some North American Black ducks to compare to:


Blacks are darker and have a more gray face.
