The oystercatcher is the national bird of the Faroe Islands. It's called Tjaldur in Faroese and Icelandic, Shalder in Shetland, Tjeld in Norway, so there is a relationship between the names in the west nordic area.
@lifeat60degrees And the name is so different in english and actually mis-named. They don't catch oysters :)
Maybe Chalder Ness in Shetland gets its name from the shalder
