Above: a Wonga Pigeon at Narara. Finding a beautiful bird dead below your window is awful.
Even worse is the distinctive, surprisingly loud “bang” of a fast-flying bird colliding with a fixed glass window pane.
There are two things you can do if you witness a strike: check whether the bird is merely stunned and can recover in a quiet, safe spot, and treat your windows to make them visible to birds using decals, screens or external patterns.
