The Golden Eagles were spotted on Sodor. They are very rare birds and birdwatchers came from miles around for a chance to see them. They were first spotted at Bluff's Cove and then on Gordon's Hill, but Thomas didn't see them. That evening, as Thomas and Percy were puffing home, they spot two golden eagles perched on a cliff-top. The two engines think the eagles are wonderful - but not as wonderful as helping each other.
