Reminds me ... I used to feed the birds in my front yard (before bears found the food, so I had to stop). There was a hawk that would swoop down toward birds feeding & drive them toward the house where they'd crash into a window, thinking I believe it was an escape route, then the Hawk would pounce on the dazed bird for an easy meal. Rather ingenious I thought.
I once had a hawk dive for the birds feeding on my deck. The hawk hit the window with a loud thud. It didn’t knock him out, but he fluttered over to the birdbath and sat there for several minutes.
Birds hitting buildings is a large problem. The reflection on windows and lights on large building cause thousands of birds to die. Some buildings have stopped night lighting. Many people put decals or tape or fluttering ribbons on windows to protect birds.
