Eurasian oystercatchers inhabit estuaries and deltas, marine environments, coastal waters, land, and woodland areas; the species’ habitat includes river mouths where fresh water meets the sea, temperate mixed forests with oak, birch, and maple trees, flooded meadows, shallow coastal waters, and taiga forests characterized by coniferous trees such as spruce and pine. The elevation of their habitat ranges up to 100 meters above sea level. They are found in biomes that include river estuaries merging into the sea, temperate mixed forests, flooded meadows, shallow coastal waters, and taiga. The climate they experience includes cool summers with temperatures between 15 and 20 degrees Celsius, consistently high rainfall, moderate seas with cool or warm water, and both cool summers with abundant rain and warm summers with plentiful rain.
