SEXUAL selection: birds. 
FM 
remarks do not apply to the many recorded instance® 
tamed or domestic birds, belonging to distinct sp 6 ^' 
which have become absolutely fascinated with e4tC . 
other, although living with their own species. 
Waterton 18 states that out of a flock of twenty-^ j { 
Canada geese, a female paired with a solitary Bern’ 1 ' . 
gander, although so different in appearance and 
and they produced hybrid offspring. A malo W'o ? 
( Mareea penelojie), living with females of the - c ‘ l j, 
species, has been known to pair with a Pintail 
Querquedula acuta. Lloyd describes the remark® \ 
attachment between a shiehl-drake (Tadorna vulpti ' 11 * , ; 
and a common duck. Many additional instances c° u 
be given ; and the Rev. E. S. Dixon remarks that “ 1 ^ 
“ who have kept many different species of gee® e 
gether, well know what unaccountable attaching 
“ they are frequently forming, and that they are 4° 3 
“ as likely to pair and rear young with individual® 0 . 
“ race (species) apparently the most alien to them® e ' 
“ as with their own stock.” ^jj 
The Rev. W. D. Fox informs me that he possess®' ^ 
the same time a pair of Chinese geese (Anser cygn° u ^ 
and a common gander with three geese. The two ^ 
kept quite separate, until the Chinese gander 
one of the common geese to live with him. More* 1 ' 
of the young birds hatched from the eggs of the con' 1 '^ 
geese, only four were pure, the other eighteen p r0 ' ,( 
hybrids ; so that the Chinese gander seems to k®.jj 
had prepotent charms over the cominoii zander. ^ '
