1. InrrRopucTION. 
In these days the camera almost monopolizes the time and 
attention of those who take an interest in the life of birds. 
It has rendered splendid service, but I believe that it has almost 
exhausted its first field. At the present moment both zoology and 
photography would profit 1f naturalists for a little time would 
drop the camera in favour of the field-glass and the note-book. 
For the many who do not care alone using a telescope, the 
prismatic binocular has more than doubled the possibilities of 
field-observation ; and when full advantage shall have been taken 
of those possibilities, not only will science be the richer for z 
multitude of facts, but then, and only then, will the photo- 
grapher, now hard-pressed for new subjects, suddenly find a 
number of fresh avenues opened up to him. 
This second paper on the courtship-habits of British birds, 
like the first, will, I hope, help to show what wealth of interesting 
things still lie hidden in and about the breeding places of familiar 
birds. A good glass, a note-book, some patience, and a spare 
fortnight in the spring—with these I not only managed to 
discover many unknown facts about the Crested Grebe, but also 
had one of the pleasantest of holidays. ‘Go thou and do 
likewise.” 
I shall first give a connected account of my own and others’ 
observations, followed by a discussion ; and in a second part or 
appendix I shall give in detail some of the material worked 
up in the first part, as well as some notes on various points not 
connected with the main subject of the paper. 
2. APPEARANCE, 
Structure first, function afterwards: I must describe something 
of the bird’s appearance before attempting to give an account of 
its habits, though I shall try to be as brief as possible, since any
