I agree with you Ian, and I think it is particularly likely to apply to birds in "boring" places - I see many more sheets from wetlands and known birdy spots than from grasslands etc, and only the most dedicated have agreed to go out and do systematic surveys along long dull stretches of road to fill in gaps and sparsely atlassed areas. Last time we tended to have maps ruled up for 10 minute blocks and on any drive we'd say "OK now we're in a new block, start a new list and see how many we can get before we reach the other side". This time people appear to say "This looks like a good place, we'll do 20 minutes here". So the birds that are less likely to be in the "good places" which may well include Goldfinches, may be under-recorded.

Not wanting to be judged as a sceptic, the supposed changing status of
Goldfinch populations in SA could be a result of a variation between
methods used to record species in different Atlas surveys.   What do
others think about comparison of results leading to assumptions of
decline when a different recording method was used in each survey?
