Quote by: Tim Birkhead

The Australian wedge-tailed eagle has enormous eyes, both in absolute terms and compared with most other birds, and as a result has the greatest visual acuity of any known animal. Other birds might benefit from the eagle's acute vision, but eyes are heavy, fluid-filled structures, and the larger they are, the less compatible they are with flight.
