The Endurance of Birds. 
The only British record of its breeding ;u captivity that 
I can find is of " one young one reared by Cordon Bleus 
(Boyd) in B. N. 1914. p. 338. Abroad Russ states that it was 
first bred by Tittel, and that he and others have also been suc- 
cessful. In Gedney we have one of the usual cheerful general 
statements of which he is so fond, about " nesting regularly in 
aviaries without artificial heat."

l)Ut a single i)air, and that these only stayed with me three years; 
they made no attempt whatever to reproduce their kind, for they 
proved to be two males.. I am not aware of any instance of 
young having been fully reared in this country. From my 
experience with the above pair I am of the opinion that it will 
winter successfully out of doors in any ordinary season, but if 
any spell of ahnonnaHy cold weather set in I should say it would 
l)e the better for the protection of four walls, and then not let out 
again till the spring. A very handsome species. 
Peaceful Dove (G. iranqiiilla ) : Its name certainly a
