The bird was spotted Monday at Maasvlakte. The animal was ringed on the island on March 3, 1972 when it was already at least two years, according SOVON Wednesday.
Never before has such an old specimen found in the Netherlands. The previous record holder was 43 years old. Oystercatchers are rarely more than twenty years.
These are also bad with this bird species in the Netherlands. Since 1990, the number of oystercatchers decreased by 65 percent. This year, according to Sovon yet forty to seventy thousand breeding pairs.
Every year, too few young oystercatchers are large. The salt marshes along the coast rinse many nests away at high tide. In agricultural areas lost many nests and young birds because early mowing of the land is cultivated. Oystercatchers also be slain by predators
