Swooping Talon

Flying is an evasion ability.

A creature with flying can’t be blocked except by creatures with flying and/or reach. A creature with flying can block a creature with or without flying. (See rule 509, “Declare Blockers Step,” and rule 702.17, “Reach.”)

Multiple instances of flying on the same creature are redundant.

Provoke is a triggered ability. “Provoke” means “Whenever this creature attacks, you may choose to have target creature defending player controls block this creature this combat if able. If you do, untap that creature.”

If a creature has multiple instances of provoke, each triggers separately.
