SyStematic LiSt Bird report for 2006 and 2007 The species accounts for the systematic lists for 2006 and 2007 were prepared by Paul Bright-Thomas, Brian Clews, Richard Crawford, Ken Moore, Bill Nicoll, Sarah Priest, Marek Walford and Ken White. Contributors of records to the systematic lists are usually identified by initials: a table of names and initials is shown at the end of the lists. The systematic lists for 2006 and 2007 were edited by Chris Heard. abbreviations and place names Abbreviations used in the systematic lists are shown below. For place names difficulties arise where there are several names for the same sites including where, for example, a gravel pit complex is named but not the individual pit . A map and guide to the main sites is included towards the end of the report to assist with identification and further detail can be found at www.berksbirds.co.uk/pits.asp. age/Sex PlaceS/LocaLitieS ad adult com Common f/s First summer CP Country Park f/w First winter (plumage) fm Farm imm Immature GC Golf course juv Juvenile GP Gravel Pit(s) s/p Summer plumage K&a Kennet and Avon s/s Second summer res Reservoir s/w Second winter r.

Theale and Moatland GPs have been combined, as often the Swans commute when excessive disturbance occurs at either site. Counts of up to 60 were received from nearly 70 sites. The count of 342 at Windsor Esplanade on Jun 30th (DF) is the highest ever recorded in Berkshire (18 more than Jan 2004, the previous record, also at Windsor Esplanade). Breeding: 39 pairs only recorded, with 117 cygnets noted, an obvious understatement of the breeding status of this species.
