of these, I do not include them in my Ust. I have thus 

 recorded the occurrence of seventy-six species of birds, of 

 which three are, however, insufficiently identified ; of the 

 seventy-three certain sijecies, forty-five may be considered as 

 residents or frequent visitors, and twenty-eight as quite 

 irregular and uncertain in their appearance. I append a list 

 showing the number of pairs of each species which in my 

 opinion probably breed here each year, and which may 

 accordingly be considered as the residents. This is of course 

 only an estimate, and is arrived at not solely by reckoning 

 the number of nests known of at any one time, but also by 

 forming an opinion as to the number of individual bnds ; 

 estimated partly by noticing the particular localities they 

 chiefly frequent, and partly by the number that are to be 

 heard singing. As of course the number of a good many of 

 the species varies someAvhat from year to year, I have 

 endeavoured as far as possible to state what I think to be 

 an average of a series of years : —
