MARTIN Prescott (Your Letters, Jan 3) is correct in stating that most biological recording is arranged by the Watsonian vice-county system, but bird recording which arguably is the most popular of all natural history recording is arranged by county, and locally the recording unit is Greater Manchester County (which, by the way, IS a county, with its own Lord Lieutenant and High Sheriff).

I should be pleased to receive any bird records from your readers for 2002 for inclusion in the the definitive county bird report, and these should be sent to me at 12 Edge Green Street, Ashton-in-Makerfield, Wigan WN4 8SL. In due course, these records will be archived at the Greater Manchester Record Office, and could be used for conservation purposes by the Greater Manchester Ecological Unit. Guidance on the type of record to send in for each bird species is found at www.gmbirds.freeserve.co.uk
