Dear Finnish and Danish colleagues,
On a Dutch birdforum the question was raised if this really is a Robin (Erithacus rubecula) and not some eastern Nightingale (Luscinia sp.), perhaps Blue Nightingale (L. cyane)?

I am hoping for some explanation regarding the white breast..

Dear all my colleagues,

Thanks all the comments about this picture. I’m still sure that this bird is “only” normal European Robin. All European Robin description match this bird except color, only red color missing. I don’t know why, that you should ask someone who knows. I’m not ringed this bird, but I was assistant Lågskär birdstation in Finland when we saw this bird.

I put more pictures in my own website. Please click this link, write robin and click search.
