1. The local patch must be in the LNHS recording area (within 20 mile radius of St. Paul's Cathedral).
2. More than one local patch can be worked but a separate list must be submitted for each patch.
3. To be counted, the species can be seen or heard, however the bird must be on or, if flying, over the patch. Birds that are clearly beyond obvious boundaries, e.g. on the other side of a river, are NOT countable even if seen from your patch.
4. Taxonomy follows BOU rules (Yellow-legged Gull and Caspian Gull are considered separate species).
5. No escapes can be counted. [Because of the recent BOU decisions regarding category C species (and self sustaining populations) it would be in everyone's interest to still record these spp. and send their records in with the rest.]. For example Ruddy Shelduck cannot be counted. Red-crested Pochard can be counted away from Inner London and Stoke Newington Res as long as it's not taking bread from the hand!
6. Observers are requested to nominate their local patches BEFORE 31 January 2010 and to send in regular updates.
7. Observers are expected to send all records to their local recorder. They can do this directly, or by logging all sightings on www.bto.org/birdtrack so they can be forwarded.
8. Updates can be made to the London Birders email chat group - http://uk.groups.yahoo.com/group/londonbirders/ or an updated list will appear on this website as from January 2010.
