With Speckled Teal having recently been split into Yellow-billed Teal (flavirostris) and Andean Teal (andium) I wasn't 100% sure that Joern was referring to flavirostris when he identified this as Ringed Teal x Speckled Teal.  I made that assumption despite the absence of yellow on the bill and Joern has now confirmed that that was indeed the case.  There were flavirostris but not andium in the collection and the pale flanks are closer to Yellow-billed too.
