I have been birding for two years and my life list is 131 species.
I am thinking of restarting my life list, and here's why:
I went to see a White-winged Black Tern at Staines Reservoir a couple of days ago. I didn't get a change to do any research before I went there, and forgot to take my book. I assumed that this bird would look markedly different from Black Tern.
Last night I checked the diagnostic features of White-winged Black Tern and the 2S bird I saw, and I can't say that I noticed these diagnostic features.
So while I know that the bird I saw was a White-winged Black Tern, I didn't personally identify it as such. This makes me want to untick the bird.
What this has made me realise is that, for me, a tick is a species that I have ID'd, not seeing a bird that I am, however reliably, informed is X.
This lead to a question: how many other species have I seen where I did not personally and satisfactorily view the diagnostic features that separate that species from similar ones? I can't reliably answer that question.
So I am going to restart my life list, and I think this process will re-enforce things I have previously learnt (and possibly forgotten) and probably learn new things in doing so.
But I wonder what other people think of this? Do you tick a bird on being 'reliably informed' (for example, someone else's photographic evidence) or do you need to 'see for yourself'?
