Eurasian oystercatchers have a typical lifespan of from 32 years and 6 months to 54 years and 2 months, with a maximum recorded lifespan of 43 years and 4 months, although the theoretical lifespan is from 8 years to 43 years and 2 months. The species reaches sexual maturity from 2 years and 3 months to 3 years and 9 months. Development begins with the "Embryo" stage, during which the embryo develops inside an egg laid in a small pit on the ground. Following hatching, the young enter the "Chick" stage, covered in grayish down and remaining in or near the nest for from 1 month to 1 month and 1 week. The "Rapid Growth Juvenile" stage follows, lasting from 1 month and 1 week to 2 years, during which the young bird resembles adults but has a darker and shorter beak. Finally, the species enters the "Adult" stage, capable of reproduction, living on the coast, raising offspring, and lasting from 2 to 40 years.
