The 3rd February found me heading up to the Cotswolds for a relaxing weekend but I couldn't resist some birding en-route. First stop was for four redhead and a male Smew that had been present for a few days on Pit 29 of the Cotswold Water Park. Arriving at around 11:00 I was fairly optimistic that these birds would give themselves up quickly so setting up my scope I was disappointed when the first scan produced no-sign of them - 25 Tufted Duck
, three Red-crested Pochard
and five Great-crested Grebe
were the highlights. I walked from the southern end of the pit to the northern end scanning all the way across both Pit 29 and 35 and then eventually Pit 38 but there was no sign of the Smew. I decided to cut my losses and head off before the rain forecast for the afternoon set-in.
I headed for Stow-on-the-Wold just as news broke of the continued presence of the Blue Rock Thrush
and just as the heavens opened. A 45 minute drive through persistent rain did not bode well. I arrived at Fisher's Close but there was no sign of the bird so I wandered to Maugersbury Park where I quickly located the bird on the roof of number 9. I watched the bird for around 30 minutes, it seemed to favour perching on the solar panels on the roof of the property. In this dull light and rain the plumage looked largely slate grey with perhaps a slight bluish tinge. On one occasion the bird dropped down to eye level when the blue plumage tones were more evident.
First identified on 27th December 2016 but by then already present for a week this bird seems to be in an unlikely location for a genuine bird. However, it is hard to believe that such a scarce bird in captivity would not support rings, even commonly kept species such as Budgerigars and Zebra Finch are usually ringed - and why has no one claimed it as their lost bird? The bird seems to have a slightly drooping left wing and some feather wear but such features are commonly seen in wild birds also. DNA analysis has indicated that the bird is of one of the southern European or North African subspecies either the nominate subspecies or longirostris.
I would have thought that most of the captive birds would be of Asian origin where trapping for the cage bird trade is more common place. While its geographical location and rather odd choice of a housing estate would not seem to indicate a genuine bird I can only see that on balance this must be a wild bird.
There are six accepted British records of Blue Rock Thrush as follows:
- 4th-8th June 1985 - Skerryvore Lighthouse, SSW of Tiree, Argyll. Male.
- 4th June 1987 - Moel-y-gest, Gwynedd. Male.
- 14th-15th October 1999 - St. Mary's, Isles of Scilly. Male.
- 25th October 1999 - Cot Valley, Cornwall. Male (possibly same bird as the Isles of Scilly bird)
- 14th-18th May 2000 - Geevor, Pendeen, Cornwall. First-summer female.
- 11th April 2007 - Elan Valley, Powys. Male
Interestingly all these are of birds in the west of the British Isles perhaps making the Stow-on-the-Wold bird a little less surprising in terms of its geographical location although the time of the year is at odds with the other British records. Surely, the spring records are of overshooting migrants from the south and therefore of the same race as the Stow-on-the-Wold bird?
Blue Rock Thrush - Number 9 Maugersbury Park, Stow-on-the-Wold
After getting my fill of the Blue Rock Thrush I headed for Kingsway in Quedgeley where up to 40 Waxwing had been present since the 24th January. I spent a fair bit of time looking around the orchard and playing field with no success and being gripped off by the locals pointing to where they had seen the birds. Eventually six Waxwing flew north overhead and appeared to land in the nearby estate but despite trying to relocate the birds I did not see them again. It was time to head to the cottage and open a bottle of red wine.
