Reply to comment by drangryrahvin in Birds see in UV. When you hang your bedsheets, they know how 'busy' you've been. by drangryrahvin

Well, There would have to be enough UV light to hit the blanket, but not get flooded by the normal light. Hence why you have to turn to lights off to see the UV reflecting off the blanket. No idea if birds are sensitive enough to be able to differentiate and block out the normal lighting.
