Seeing a bird's wing signifies wealth and benefit. Sometimes it signifies very valuable things and sometimes rank and position. A bird's wing is also interpreted as a sword, knife, spear, clothing, or wealth and blessing.
Seeing bird feathers signifies goodness and benefit. Kirmani said that filling a place with bird feathers signifies marriage. Feathers of a bird whose meat is lawful to eat signify lawful wealth; feathers of a bird whose meat is not lawful to eat signify unlawful wealth.
