Directions
Navigation - Migrating birds acquire directional information from landscape features and wind direction which can be influenced by major land forms, scents, the stars and sun as well as Earth's magnetic field. Increasing evidence indicates that birds collect magnetic field information through specialized eye receptors. Migrating eagles fly during the day at speeds averaging 30 miles per hour. To help them soar, eagles use thermals, which are rising currents of warm air and up-drafts generated by terrain, such as valley edges or mountain slopes. Soaring is accomplished with very little wing-flapping, enabling them to conserve energy. Long-distance migration flights are accomplished by climbing high in a thermal, then gliding downward to catch the next thermal, where the process is repeated. Bald eagles tend to migrate in groups. A "stream" of migrating bald eagles can be twenty to thirty miles long, with birds spread out about a half mile apart. The best place to view bald eagles along the Hood River Canal is May through early July. This location requires minimal route exploration.
