Nordic?

Continuing the substandard subspecies theme, with which Geoff has whole-heartedly joined in, I offer these pics of a candidate for "Nordic" Jackdaw; picked up as I was driving down the Niddrie Mains Road towards dusk, not the best spot for digiscoping and it was quite active along the main road, it was noticeable that the white stripe varied in impact according to viewing angle, as per pics below. Front view shows the "headlamp" effect noted by Geoff in January.

It is certainly not as obvious as some, moreover it would not seem to be a good time for Scandinavian arrivals - Jackdaw is a late autumn migrant, main movement picking up from the middle of October and continuing to late November (trektellen graph). Perhaps it's just a turrium intermediate, as suggested by Geoff for his Irish birds? Intermediates also pondered on Birding Frontiers.

Subsequent records of presumably same bird in same neighbourhood have now shown it is a resident breeding bird, and by 2018 is at least 8 years old, all known sightings:

  1. 22/9/11 Niddrie, S Welch, as per above
  2. 31/10/11 Niddrie, S Welch;
  3. 4/11/12 Craigmillar, by Geoff Morgan, his first sighting;
  4. 30/1/13 Niddrie, S Welch;
  5. Seen at least 3 times around Craigmillar, Geoff March, August and September 2013 (paired);
  6. 19/12/14 Niddrie, S Welch [photo on Twitter]
  7. Some time in 2014 independently discovered by Martin Scott;
  8. 21/11/15 Niddrie, Geoff;
  9. 24/1/16 Niddrie, Martin particularly interesting as on same day likely same bird seen by Geoff at Alnwickhill/Mortonhall, 3-4kms distant, regular Jackdaw roost flights across city;
  10. 14/5/17 Niddrie/Craigmillar, Geoff;
  11. 9-10/8/18, still, paired, at front entrance to new Home Bargains store, recently built on former open area haunt on north side of the road.
