The following sub-pages detail bird species where records on Anglesey are infrequent.
In compiling these details, I have gone back to the original BBRC, WBRC or Cambrian Bird Reports wherever possible to add page details as part of the references for accepted records. Where this hasn't been possible, I have referenced previous publications - notably Birds of Anglesey (Hope and Whalley (2004).
I am appreciative of the work of Reg Thorpe where species have since dropped off the WBRC list and to Steve Culley for access to copies of Cambrian Bird Reports.
