Iceland & Kumlien's Gull 3cy February(Chris Gibbins) Here are some thoughts on 2nd winter kumlieni versus glaucoides that
may help with birds in Western Europe. To preface these observations, I should add
that I'm not really too experienced with kumlieni (so can't speak from long
term experience with many birds), but I do look closely at all the 2nd winter I get nervous with 2nd winter white-winged birds because I see large variability in birds Birds like this last one are often discussed as kumlieni candidates, partly or wholly So, my working model in Scotland falls back on what we have known for a long time, namely that kumlieni in Newfoundland are not just dark, but have Of course this is not new, but some statistics help emphasise the point. I've just done a count, and 32 from 33 2nd winter kumlieni from Newfoundland that I have in my collection show this pattern. And it is not just the dark ones - even very pale/otherwise white kumlieni show this (e.g. this bird). Bigger sample would be better, but this high % is persuasive. On the darker (assumed) glaucoides I see here in NE Scotland, the
intensity of shading is uniform across all primaries, so they lack the So, until we know more about 'dark glaucoides' I work with a rather a If I apply these criteria, then I've only seen one good 2nd winter kumlieni here in These points, made by Chris, are agreed upon by Bruce Mactavish, who sees lot of kumlieni in Newfoundland, where he lives. He did notice on some of the
suspect Kumlien's from various parts of Europe in the last few |
