Fwd: Bird deaths from window collision query

[Robin Eckermann via Canberrabirds <>]

Our situation is a bit unique - we have and entry foyer with a wall of glass on each side - so birds can see through to trees etc on the other side and its tempting for them to take a short-cut.

After lamenting quite a few window collisions - many with fatal outcomes - I loosely strung 5 or so trands of fishing line between two chain drains that are located about 3m in front of the window. They were not in place at the time this picture was taken (from inside), but you get the idea.

I'm not aware of any collisions since putting this deterrent in place. The fishing line is barely visible - but (at worst) if birds fly into it, the result is a "soft" collision because the dangling chains give the fishing line some additional "elasticity".  Birds don't get entangled, and the locals seem to quickly learn its not a viable short-cut. Obviously this approach only suits windows where it is feasible to place the fishing line some distance in front of the windows.

Prior to this, I tried a fake raptor suspended from the overhang - but the birds seemed to overcome any fear of it fairly quickly.
