You might be right John. Birding is for fun but I should think that for many birders it is also important to them that their IDs are correct.
Your example is a good one although perhaps it is more critical when both species are rare? [Last time I saw a Cory's in the UK close enough to check (on a pelagic off Cornwall) , I hadn't even heard of Scopoli's!]
I remember in the past hearing reports of numbers of large shearwater sp. off the south coast, so what's wrong with [SIZE=-1]Calonectris[/SIZE] sp.?
Another example (from North America) is here. The number of Manx records in California are similar to the number of Fea's/Zino's in the UK.
Cheers,

The point I was making is that most Cory's seen from land are not seen well enough to exclude Scopoli's, but I can't see people putting "400 Cory's/Scopoli's past Porthgwarra" onto RBA. Or worrying about the fact that they haven't.
