Oenanthe (hispanica) melanoleuca

A very rare species in The Netherlands. Until this bird appeared, there were 6 accepted records for the country's list, 4 of the western (sub)species hispanica, 2 of the eastern melanoleuca, plus another record of hispanica still under consideration.
I managed to miss the previous twitchable bird because of my stay in Sweden at that time. So the appearance of this one was very welcome! Although it was reported quite late on a Sunday afternoon, a twitching team was quickly formed which fortunately arrived in time to witness this rare event. The bird was quite tame and approachable, resulting in high-standard pictures that have been published in Dutch Birding. Some video stills from me are shown here. The next morning the bird could not be relocated, so our quick action had paid off!
Eastern and western Black-eared Wheatears were until recently considered to be subspecies, but under the phylogenetic species concept they were split (although true phylogenetic evidence is lacking!). Fenotype differences are minimal, however, with no conclusive differences in morphological features at all. An excellent article by Magnus Ullman (Dutch Birding  vol. 25 (2003), pp. 77-97) recently described the major pointers towards separating the two.
