Hi. I think the flashing white strobe lights definitely make a difference. I fly M30's at work. These come standard with top and bottom flashing beacons. I always have the beacons on when flying and the Wedgetails and other birds of prey don't come near the drone but circle from a distance. Even crows stay away but when the lights are off the birds will have a lot more interest in the drone and get a lot closer. I think it's flashing light messes with their eyes, similar to us being blinded by a flash. Birds eyes are a lot more sensitive than ours so this constant bright flashing light may be making the difference.
