I have shiny CDs hanging from monofiliment in my windows and dark
silhouettes of raptors taped to the outside of my window shades...
since putting those up it's very rare that birds attempt to fly
through the glass. Plus there is almost always a cat in my windows
trying to slap at any birds that come near which also warns the
feathery things away.
