The birds there never poop on the people praying at the Ka'ba, or on the Ka'ba itself, ever. Birds never fly directly over the Ka'ba, ever. You can watch them for hours, and not one will cross over the Ka'ba.

Note: The Ka'ba is the brick building in Makkah at the center of the grand mosque there, which is covered with a black cloth. All Muslims around the globe face the direction of the Ka'ba when praying.
