Some villagers who wanted to protect a rare bird's 1 have finally solved the mystery of the disappearing eggs. For thet last three years, a pair of rare birds has built a nest near a village and every year the eggs have2. Last year, the villagers suspected thieves of stealing the rare eggs and selling them in the market. This year, organized by local birdwatcher Margery Thisk, they spent weeks guarding the nest-site. They installed a burglar alarm and kept watch with a powerful video camera. Despite all their careful precautions, they found the eggs missing again. However, the video recording has been used to 3 the thief, who is Mrs. Thisk's black and white pet cat called Flash. “We were watching the video playback when Flash suddenly 4 and ran away with one of the eggs,” said Mrs. Thisk. Next year, the villagers plan to fix a cat scarer to the tree where the birds build their nests. This 5 makes a very high-pitched noise which birds and people cannot hear, but cats can and they do not like the noise at all.
