Read before the Wellington Philosophical Society, 29th October, 1S90.] 



Probably no section of New Zealand zoology has received 

 such careful attention or been so thoroughly worked as the 

 birds. Their beauty of form and colour, and the peculiar 

 interest attaching to their life-history — their natural habits, 

 their song, their wonderful modes of nidification — and their 

 general ministration to the requirements and caprices of man, 

 all tend to make the study of oui* birds more attractive than 

 that of any other branch of natural history. So much has 

 already been written on this subject that it might reasonably 

 be looked upon as a well-nigh exhausted field. So far, how- 

 ever, from this being the case, new forms and characters of 

 bird-life, and new facts in the liistory of even om* commonest 

 species, are being continually brought to light ; and it seems
