In 1916 an English vicar stole the last native white-tailed sea eagle eggs on Skye, and the last adult was shot in Shetland two years later. However, the species was reintroduced to the island of Rùm in 1975. The bird spread successfully to various neighbouring islands, and 30 pairs were established by 2006. Despite fears expressed by local farmers, the Royal Society for the Protection of Birds (RSPB) are in process of releasing up to 100 young eagles on the east coast in the Forth and Tay estuaries. The red kite was exterminated in Scotland in 1879, and a reintroduction programme was launched by the RSPB in the 1980s. Although the species has made significant advances, it is estimated that 38% of the 395 birds fledged between 1999 and 2003 were poisoned and a further 9% shot or otherwise killed by humans. The RSPB stated: "it may take a custodial sentence before people engaged with this activity begin to take the matter seriously".
