Bob and Mr. Bentley are both members of the bird-watching society, for whom Bob is building a 'hide'. Spud is intrigued, but Mr. Bentley tells him he is only allowed into the nature reserve if he promises not to scare any birds. So Spud decides to find something else to scare. Mr. Bentley hopes to see the Grebe Warbler which is due to pass by on its way south, and the Machines speculate as to the Warbler's appearance. Their vision of a monstrous bird inspires Spud to disguise himself as the Warbler to scare them. The hide complete, Mr. Bentley and Bob go inside, while the Machines camouflage themselves. Spud appears and his hilarious disguise makes the Machines laugh. Scared by the disembodied voices, Spud runs off - only to meet the real Warbler, who follows him back to the hide. Spud keeps very still as Mr. Bentley takes some photos, but the sight of the camera scares the Warbler into a tree.
