After several misses, I finally was in the right place at the right time to see the Mexican Duck that's been in residence in the Pleasant View/Sale Lake area in Boulder apparently for quite some time. I've got a question about the purity of this particular individual stemming from the upcurling tail feathers as shown in the photo below. Does this character mean that it is not a pure Mexican Duck, but rather a hybrid to some degree? I read Jack Bushong's excellent piece on Mexican Ducks on the ABA website which mentions this very issue.
-- Thanks for any input,
