Well, lots of living birds do exactly that. Think of all the birds with
conspicuous wing and/or tail patterns, some of which are often most visible
in flight or on landing (the contrasting white outer tail feathers of many
songbirds, the "flash-pattern" wings of the sunbittern, the extraordinary
tail plumes of many species of birds of paradise (not the trains of
peacocks and quetzals, of course, which do not involve the tail), and the
even more extraordinary display feathers on the wings of Standard-winged
and Pennant-winged Nightjars (not to mention the sound-producing wing
feathers of birds like the Club-winged Manakin or the African Broadbill.
