As with leucistic individuals, albinos can retain carotenoid pigments if normally present in the plumage. One of these is called ‘progressive greying’, which also results in white feathers. It looks to be about the same size as the jackdaw in the bottom right of the first picture.

Not the best quality as they are long distance and I wasn't out to take photos so used what I had with me. 2006

Little did I realise that I was stepping into a definition minefield when, after finding an oddly coloured jackdaw earlier this week, I decided to find out more about leucism. 2012 2008 One source says the plumage of leucistic birds is pale or washed out though the normal pattern and colour is discernible, another reports that the cells of the affected plumage lack the ability to produce melanin and the lack of melanin produces white feathers, and yet another states that leucism is caused by a reduction in several types of pigment, not just melanin. 2009 Tide out, overcast, windy and in the mid-fifties. So, rightly or wrongly and very simply, I’m defining my leucistic birds as those whose feathers would normally be black or some other colour but are actually white (but they’re not albino, as they have their normal eye colour). This bird only has very small white patches. You can unsubscribe at any time.

Most albino birds die soon after fledging, primarily as a consequence of their poor eyesight, and albino birds are not thought to progress to adulthood in the wild. Not the best quality as they are long distance and I wasn't out to take photos so used what I had with me.
