If we attempted to introduce N. American migratory species, 
the geographical conditions would probably defeat us. The 
Channel, the Alps, the Mediterranean, and the Atlas and 
Sahara, oppose such formidable barriers to the inexperienced 
migrant that we might expect to fail. 
I merely suggest that we make a beginning with certain 
selected resident forms whose known habits afford us no 
expectation that they would prove nuisances if our scheme 
succeeded. 
The Blue Rock Thrush is an insect-eating bird. I am 
not aware that it attacks fruit. It has a graceful appear- 
ance, a charming colour, lively habits, and a sweet little 
song. It frequents houses, churches, and ruins. I suggest 
that it might be introduced into the Cheddar Gorge as an 
experiment and carefully watched. 
The Meadow Bunting (E. cia) breeds as near to us as 
Brest. It is a prettily marked creature, does no harm, and 
is so rare as a visitor that nobody ever expects to see it 
along our shores. ‘Try it on the Chilterns. 
The Alpine Chough has never occurred with us, for the 
Oxfordshire occurrence was an escape. This bird is not a 
coast-dweller, and if introduced into Scotland, Derbyshire, 
and the Lakes, might settle with us, for it apparently does 
not move far from its stations. Its wild note, its aerial 
gymnastic, and cheery habits endear it to those who have 
made its acquaintance in Switzerland, the Tyrol, and the 
Pyrenees. It has no known vices, and would get along 
wherever coleoptera and snails could be found. 
I would like to suggest, in conclusion, that selections 
should be made among birds from the temperate zones 
which have never occurred in Europe; say from Japan, 
Vancouver, &c., and attempts made to introduce them here, 
giving preference to quiet coloration and good voice, rather 
than to briliant plumage which would attract the Sunday 
gunner. Our working class is still too uneducated to assist 
experiments which call for self-restraint, as the North Repps 
attempts with Parrots showed.
