An adult Bald Eagle would be much much larger than a crow. Cornell's Birds of North America Online lists the adult Bald Eagle at 71 to 96 cm head to tip of tail. BNA list the American Crow at 43 to 53 cm. Big difference...almost double.
What about the bill & legs/feet. Bright yellow on an adult Bald Eagle. Black on a American Crow. Do you recall the color of the bill & legs of your bird?
