They didn't even need the flare, to confirm his basic suspicions; as they swept over the city, the sound of the engines seem to have drawn quite a bit of attention. All around the city, figures move between the buildings, keeping to the shadows, moving fast, almost animal-like, though clearly humanoid in shape. As they set down, their sensors will report the crowd closing in on their location, but the flare seems to be the last straw. As the light fades, a howl goes up, from somewhere in the city, a howl echoed by hundreds, maybe thousands of voices, followed by the thunder of those same thousands of feet, stampeding towards them, their inhuman cries ringing in the air.
