sort o' ot -- maybe some good news on extant dino's and towers



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

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..."
