92 BIRD WATCHING 



The demeanour of the two birds is at once visibly 

 affected, and they begin to pipe again, though not so 

 vigorously as before. They continue to do so, more 

 or less, at intervals, the third bird (the female) remain- 

 ing always passive, and never once piping. All at 

 once one of the two pipers flies violently at the other, 

 who flies off, and is closely pursued by him. They 

 alight -it would seem together on the edge of a 

 great rocky slab, but are instantly at some little 

 distance apart, looking at each other and bearing 

 themselves after the manner of rivals. How they

 birds are often so quick, that the eye, though it may 

 follow, forgets them as they pass. On another occa-

 from a rock a little off the shore, becomes excited,

 rock. On alighting, he instantly runs to the piping

 soon flies away. The piping instantly ceases, and 

 the two birds assume normal attitudes.

 courting the female differs both from its ordinary one, 

 and, as I think, from that of the female. The usual 

 note is a loud 'wich, wich, wich,' or some similar

 tinuance, beginning with something like 'kee, kee, 

 kee, kee, ker-vie, ker-vie, ker-vie, ker-vie, ker-vie,' a 

 loud and ear-piercing clamour. Gradually, however,
