Perhaps adjusting the flash frequency could reduce fatalities even further...

"[...] and multiple comparisons procedures determined that towers lit at night 
with only flashing lights were involved in significantly fewer avian fatalities 
than towers lit with systems that included [...} a combination of red, flashing 
lights and red, non-flashing lights. [...] Our results suggest that avian 
fatalities can be reduced, perhaps by 50â71%, at guyed communication towers 
by removing non-flashing/steady-burning red lights..."
