Songbird Deflector

Bird Deflector

For birds, glass windows are worse than invisible. Because they reflect the sky and trees, windows look like good places to fly into. Up to about 1 millions of birds die each year from window strikes in North America.

Feather shapes scare birds away

Maybe because they look like the cartoon image of dead bird here, birds avoid floating single feather shapes. Birds also stay away from, moving, shiny objects. Vertical lines are better than horizontal lines as a deterrence.

Outlines from my feather drawings  were used as templates to cut out shapes from thin aluminum flashing.

The aluminum was brushed with an angle grinder. Wires with fishing line style swivels keep the shapes in-line.
