This Blue Jay is making sure the feathers don't get wet.

Canon 40D with 400 f5.6L lens @ 1/1000, f6.3, ISO 320, with - 1/3 compensation @ 400mm focal distance (not including digital sensor crop factor).

I often give a small negative compensation with birds that have a bit of white feathers on a basically darker image to prevent blowing out details in the white.

Cheers,

Mike
