TICHODKOMA. 443 



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.
