Confusion and your help required please.

I have agreed as it is a Stonechat. However I read with interest the comment posted by RoyW on the first bird in the carousel above. In it he says that S. torquatus is the African Stonechat and in fact S. rubicola is the European Stonechat.

I often get confused with sub species etc. Is there some cross over in ranges of the two birds? Can we even tell from this image?

Please help, your confirmation on this issue would assist me greatly.

Agreed

I agree, but am swayed by Martin Harvey's recent posts on using the names iSpot suggests. I am going to follow that, from now on. No more Chroicocephalus changes for me! rubicola is probably right, then, but I'll wait for iSpot to catch up and let them change it.

OK

Can I pose a question then please, if you observe say a Black-headed Gull and want to post it, should you use Larus or Chroicocephalus ? It's a problem to know what to do for the best.

You choose

I used to update names whenever possible, but it actually does not matter, if iSpot is intending to get round to it one day. You could add Larus or Chroicocephalus, I suppose. If you look at a sighting where Chroicocephalus is the accepted ID, you'll see that the links to the NBN still use Larus anyway. Like this one...

I think it is up to you; but, if we are choosing to use and enjoy iSpot, presumably we are choosing to use their names, too?

Synonyms or splits?

We have to be careful here as there is little difficulty in using either name for synonyms such as Chroicocephalus ridibundus and Larus ridibundus.

However splits indicate that we are dealing with different species, so it is probably correct to use S.rubicola.

If ispot had been entirely UK based this would probably not be a problem, but as it has become more international recently it may be prudent to use the up to date split.

All the best

Good point

Good point, David. iSpot, of course, is still on the old torquata, so it's doubly wrong! It is what we currently have to work with, though, when entering an ID for Stonechat, so it's still worth agreeing with the above.
