anti-crash for birds..

I read about this.. because we have a sliding glass-door leading out to our deck on the back of the house. The bird feeder is right out there.. and birds frequently fly into the glass because of its reflection. We'll hear a "thump"... and look to find a little bird dazed on the deck. There's usually plumage stuck to the glass.. at the point of impact. ... (that's gotta' hurt..)

Lynne and I love the wild birds.. and since our kitties have all passed-on; I've been paying extra attention to the feeders.. and keeping them constantly stocked with a variety of treats. There's a LOT of activity.. and we don't want to see any harm come to the birds.. if we can prevent it.

Window-impacts are frequent.. and a major cause of fatalities if a bird strikes the surface head-on at a high rate of speed. One of our bird-books recommended hanging paracord (string) vertically across the front of the glass.. 3-4" apart, which provides borders within the reflection, that the bird can see.. and hopefully veer-away.

Here's what I came up with..
