Over many a quaint and curious volume of forgotten lore—

He could see the "line" from the sky. Some great weird thing. He didn't know what it was, it seemed too straight to be... normal. So, it demanded more investigation from him.

He came down from the sky, hovering above the great thing as he inspected it with his head tilting this way and that. It didn't seem dangerous, and so, he came closer and closer until finally he landed amongst the snow and stone. He used one of his taloned feet to kick snow away so that he could expose the stone beneath more easily. Then, he began tapping at it. Hm! It seemed normal. Just far too straight. How strange. He tap tap tapped it once more for good measure before sitting up and looking around.

He could feel his stomach starting to complain. What he wouldn't give for something tasty to munch into. Maybe he could find some carrion or harass another bird off its meal. Pfft, as if. He hadn't seen hide nor feather of another bird since he'd gotten to this place.
