Well Nic I Just Checked The Manuals, And The Procedure Company, In This Case is Airbus, Their Manual Reads out To Open The Lights That Can Distract The Birds Or The Pilot Or Co Pilot Should Be Visually Seeing Any Bird Activity Around Their Aircraft.

Well Now A Days Spoters Are On The End Of The Runway And If They See Bird Activity AROUND They Would Take A Shot At Them.

Aviate, Navigate, Communicate
