Some of these species are very rare or very local in Ireland^ such as 

 Passer montanus, Garrulus glandarius, and Columba cenas. 



The distribution of tlie other 26 residents may be tabulated as follows. 

 If the total number of residents be added together^ it will be found that 

 Scotland heads the list with 98, England follows with 95^ whilst Ireland 

 has only 89. It must, however, be remembered that these figures are 

 exclusive of many species of Winter Visitors, a small minority of which 

 are left behind in autumn, and are presumably residents, though the great 

 majority of the individuals representing the species in our Islands migrate 

 in spring to more northerly breeding-grounds, and thus cause the species 

 to be included in the list of Winter Visitors. It is also exclusive of a few 

 species of summer visitors, of which some individuals remain with us all 

 the winter.
