6. Discussion 522 
* Tt was not until this paper was in print that I realized that the word Courtship 
is perhaps misleading as applied to the incidents here recorded. While Courtship 
should, strictly speaking, denote only axte-nuptial behaviour, it may readily be 
extended to include any behaviour by which an organism of one sex seeks to “ win 
over” one of the opposite sex. It will be seen that the behaviour of the Grebe 
cannot be included under this.  ‘‘ Love-habits”? would be a better term in some 
ways; for the present, however, it is sufficient to point out the inadequacy of the 
present biological terminology.
