The range on this bird does not match any measurement in the source (there is none to be found) and it doesn't match the actual map source in the article. This "Did you know" was outright supported by the page and wrong according to the data present in the article. ChrisGualtieri (talk) 05:09, 6 May 2014 (UTC)
 * @ChrisGualtieri, JohnBlackburne, Totodu74, Cwmhiraeth:  Hey Chris. The source says under "Key facts" on the left hand side of the page: "Distribution size (breeding/resident) 376,000 km2", so I take it you simply missed it when looking. Whether it is poor information is another issue. The map distribution shown, and from which I assume the sq.k. area information is a reflection of, is near identical to that shown on the map provided by IUCN of its range (though this may be a circular observation since IUCN cites BirdLife as one source of its information, though it cites others as well). But Harrap's information is as of 1996 whereas these two are as of later dates. So I guess my question is, what makes you so sure information from Harrap (who is certainly a reliable source), should be viewed as the last word – enough to remove information that is verifiable to Birdlife International and the International Union for Conservation of Nature (which are certainly also reliable sources), with edit summaries stating that it is not at all a close call? You may very well be right, but I want to understand your rationale. Here's another issue. I have no idea of the sq.k. area shown on the Harrap-derived map. I couldn't even hazard a guess, though it appears to me to be zoomed out from the other maps. Are you sure it's a significantly smaller area? More critically, this article was translated from the French featured article and the map was drawn by its main contributor. I am not sure at this point if the map comes from him looking at the places Harrap textually provides as places where the bird was observed, and drew it as he saw fit, or whether he redrew a pre-existing map. Certainly the pages from Harrap (which I am viewing right now) have no map image shown (see for yourself). I have no idea how a map of a species' range is supposed to be drawn and whether there are international conventions on how you draw the areas to show the extent of a bird's range (and whether that was followed). Certainly, if this is so, between a map drawn by a Wikipedian, versus those drawn by reliable sources, the former is the runt of that litter. I've pinged him.--Fuhghettaboutit (talk) 01:30, 7 May 2014 (UTC)
 * Very interesting. The actual text listed does not even support the map from which it and Birdlife denotes. I think its a bit of a misuse of range (as I am seeing it) to label the size so large. You have localities that have them, but ultimately the range provided has one bird per 25 square km and large portions of the area unable to support them. I am ever more curious as to why this conclusion was reached and why the key information goes back over 80 years. Many records are singular and some are questionable, let alone backing residency in the area. For an area larger than the whole of Germany to be the "range" of the rare and highly localized species seems to be an obvious nonsensical statement. And the right side didn't load for me when I viewed the Birdlife site, weird. I did a ctrl-f for the measurement since I was in disbelief it would be missed otherwise and I saw the map and figured it was the basis of the area claim. An error on my part in this case, but the range issue has become even more pronounced I think. ChrisGualtieri (talk) 04:21, 7 May 2014 (UTC)
