Shot this at Palm Beach Zoo - curious as to what the naming is - not in my North American book ? .......... Thanks !
This duck is not a Hottentot Teal it lacks the dark cheekpatch\/smudge that is diagnostic. I believe it is a Silver teal - note the yellow patch at the base of the bill.
Since no one here has definitely identified it, you may want to consider asking the zoo officials. Bud
Try googling Silver Teal- go to images and look for the Diagnostic features IE the Yellowish patch at the base of the bill as well as the barred feathers on the tail coverts.
