The large white wing patch covers all of the:
Greater secondary coverts
Secondaries and primaries
Question 2 Explanation:
The secondaries (including the tertials - the innermost secondaries) grow from the "forearm" bones, and are essentially all white in this species. Technically, there is a little black on the bases of the outer secondaries, and the outer web of the outermost secondary is black. This color contrasts with the slightly browner primaries (which grow from the "hand" bones) and makes it easy to distinguish the two feather groups here. When the wing is folded the blackish primaries are almost completely hidden under the stack of white secondaries.
