Index
Birds
Every volume of the Annual report contains a list of bird species present and it was felt to be pointless to index every entry in these. Therefore only when special mention is made of the rarity of a bird (up to its third record) has the list entry been indexed. No account has been taken of the acceptance or otherwise of the sighting as, more often than not, this was never reported. This has lead to two entries under, for example, "Second record" if one was not accepted.
