Start << Back Watch This! >> Stay Tuned! U27 will Keep in Touch Look at U27's body shape as she flys away. Can you see the bright white of her tail feathers? Notice her wide wing span. Bald eagles are easy to identify when you know what to watch for. U27's new radio transmitter will keep her in touch with us. Her light, high-tech backpack sends signals to orbiting satellites. Those signals let us track her on our Journey North maps. Will the signals lead us to her nest site farther north? Stay tuned. The answer will arrive with the spring!
