有时候老办法是最有效的。俄联邦安保局驯养了12只猛禽（包括苍鹰，猫头鹰和游隼）用来驱离克里姆林宫上空的乌鸦和鸽子。但现在，也在测试用这些猛禽对付小型无人机。它们栖息在Konstantino -Yeleninskaya塔楼的炮台里。
Sometimes the old ways are the best. The Federal Protection Service uses 12 goshawks,
eagle owls and peregrine falcons to scare crows and pigeons away from the Kremlin,but now they are also being trialled as answers to smaller drones. They roost in the turret
of the Konstantino-Yeleninskaya Tower.
