Question 2 Explanation:
The white patch includes all of the median coverts and most of each greater secondary covert. When the wing is folded the broad white edges on each greater covert conceal the black parts of those feathers, although you can still see the ghost of the black parts showing through. Similarly, narrower white edges on the secondaries and tertials merge when the wing is folded to form a white streak back towards the tail.
