Lighting configurations for birds

Text on the image reads "Shield lights to direct illumination inboard and downward to the extent possible". Two vessels are depicted. The vessel on the left shows downshielded lights directed inward and so this vessel is less of a collision risk to birds. The vessel on the right does not have its lights downshielded and is a collision risk to birds.
