Trailing edge you say? So not designed to mince up birds, that's a relief.

Oh they’ll still mince birds, just with the blunt side

Most of the bird deaths are not actually physical strikes - it is a result of the massive change of air pressure as the blades pass at speed. Evidently painting one of the blades black - or some contrasting colour - keeps a lot of the birds well away.
