provisional atlas maps

This concerns the maps which will appear in the national atlas rather than our forthcoming county publication but, as both will be based on the same data (your records!), I'm sure Ian won't mind me posting this here.

I'm in the process of checking through the provisional maps and several anomalies are occurring. Many of these concern H codes which observers have given to birds seen in suitable breeding habitat, or P codes for a pair in suitable habitat. Whilst the habitat may well have appeared suitable, and the code entered seemingly correctly, it is resulting in Possible or Probable breeding records appearing on the map where we are almost 100% certain that the species in question did NOT breed.

The other regular problem is where observers have entered FL for a juvenile bird, where it really should only be used for recently-fledged and still dependent young.

I am querying these records with contributors as best I can, but it would help me enormously if those who sent in atlas records could take the occasional look at the atlas website and check if I have queried any of their records. I am trying to e-mail everyone concerned but this is not always possible.

Many thanks, Steve

and if you are asking "who checks the checkers?" Steve Atkins will tell you what an effort it was to make me downgrade my atlas record of displaying Bramblings in Greenfield They were displaying (honest) but probably don't deserve a spot on the breeding Brambling map!
