So, dark sky's, early morning, cloudy skies, bright sun, late on the afternoon, rain, your magic exposure is 1/2000 sec. f8 @ iso 400.
What I described applies to white birds in direct sunlight. It works from just after sunrise to just before sunset, even when everything else is dark or in the shade. If the sun is shining directly on the white bird, LV 15 will work to protect your raw highlights.
In other situations, just use matrix/evaluative metering. The DR of the scene will be low and you won't need to worry about blown highlights.
For most cameras, just look for highlight warnings. If you see them, speed up your shutter until they go away.
