Butterfly-birds in many languages and in countries as far apart as Switzerland and Eastern Tibet, Their trivial name of Wall-Creeper is given them on account of their resorting to the walls of buildings and retaining walls of roads etc, when they leave their wilder, uninhabited summer forests and visit the lower hills and plains of Europe. It is a not uncommon cage-bird in Switzerland and will lay freely in captivity, though no instances are recorded of their rearing any young under these conditions.
