348 BIRD BEHAVIOUR 



domesticated till long after a period of commensal 

 existence ; at any rate in the East, the true wild 

 Bliie-rock of the Eastern race intermedia without 

 the white patch on the back, is still found breeding 

 not only in ruins, but in inhabited houses and in 

 the sides of wells. A wonderful bird is this familiar

 important species to man. The Twikey, however, 

 supplied its place with the aborigines of Mexico,
