Back in the late 1970's I was staying in a room near the top of the beautiful Ilikai Hotel, right on the water in Honolulu.
The room had large sliding glass doors leading onto the balcony overlooking the ocean. I sometimes turned off the air conditioning and left the doors open at night.
One morning I awoke to find five or six pigeons in my room, picking through some popcorn left over from the night before.
I gathered up the popcorn and used it to lure the pigeons out into the corridor and down to the elevator. I called for the elevator and when it arrived I tossed the popcorn inside and the pigeons followed.
I then pressed the button for the ground floor and watched the doors close so the elevator could descend. I assume everyone got off safely on the ground floor and found their way out of the hotel
