In my world my protagonist is stuck in a city that is being lain siege to. The city needs to get a message to a fleet.
Messages are delivered by sharp-skinned hawks (actual bird), but the problem is the invading army is using ferruginous hawks (actual bird) to capture these hawks before they can take flight.
In order to solve this problem a large flock of pigeons will be painted to look like the sharp-skinned hawks as decoys.
Will paint have any effect on the flight ability of the pigeons?
