This bird has caused lots of discussion over the last year or more and there have been loads of suggestions as to its identity. It has been suggested as an aberrant Spur-winged or Long-toed Lapwing, both extremely rare species in this area. There have been suggestions that it is a partially leucistic Blacksmith or White-crowned Lapwing, but these also don't tie up exactly. And then there is the suggestion that it is a Blacksmith x White-crowned Lapwing which is also slightly aberrant. The latter ID is a suggestion that I first put forward about a year ago and, based on all the current evidence I have seen, I am still sticking to that at the moment...
This bird shows fully black primaries and secondaries, a feature which would certainly support Blacksmith Lapwing involved in the parentage. The bird also shows white lesser and median upperwing coverts with mostly black greater upperwing coverts with what appears to be a white trailing edge. That upperwing pattern does not match any local species of Lapwing. Yes, this is an aberrant bird, but a semi-leucistic or semi-albino species would still show the correct pattern on the wing, even if some of the feathers were white. Spur-winged Lapwings have brown upperwing coverts (no black in them at all) and Long-toed Lapwing have white upperwing coverts (also with no black in them), so where does the black come from. The only species that shows some black in the upperwing coverts is White-crowned, hence the suggestion that this may be a hybrid Blacksmith x White-crowned.
I have not heard any recording of this bird’s call, so can’t really comment on that. There is a photo which shows the bird in question alongside Blacksmith Lapwings and it seems pretty much the same size. Spur-winged is a slightly smaller bird and, although it may be difficult to ascertain this when the bird is on its own, next to Blacksmiths it should be noticeable.
I just think we need to look at this realistically – we have an aberrant bird whose plumage does not seem to match any particular species at all. Two very rare contenders are being suggested, both of them semi-albino or semi-leucistic, and both of them EXTREMELY rare in the country. What plumage features and bare part colouration is visible does not match either of these two species spot on. The other 2 contenders being suggested are common in the area. And, although this is an aberrant bird, the plumage features and bare part colouration again do not match either of these two species exactly. The third suggestion is of a hybrid between 2 species which commonly occur in the area and could possibly explain some of the plumage anomalies visible in the photo. I’m afraid that, for now, I am going to take the conservative route on this one and go with the latter, but I would love to be proven wrong...!
Enjoy the continuing puzzle...! That's what makes bird ID such fun...
