Hooded Merganser and Asian Brown Flycatcher added to Category A
As a result of BOURC’s ongoing review of Category D species, two species have already been added to Category A – Hooded Merganser (BOURC 37th report, Ibis 151: 224-230) and Asian Brown Flycatcher (BOURC 38th Report, Ibis in prep.) and five species have been moved to Category E – Cinereous Vulture, Northern Flicker, White-winged Snowfinch, Chestnut Bunting and Blue Grosbeak (BOURC 37th report, Ibis 151: 224-230; BOURC 38th Report, Ibis in prep.). In addition, Baikal Teal will be added to Category A in the BOURC 38th Report (Ibis, in prep.).

The following species, along with Bald Eagle as previously announced (Ibis 151: 224-230), are to be retained in Category D:
Great White Pelican Pelecanus onocrotalus
Four records: Norfolk, 1964; Essex, Kent, Humberside,1975; Kent, Essex, Yorkshire, Angus, Moray, 2006 and a second individual in Norfolk, Lancashire, Northumberland, Cambridgeshire, Suffolk, Denbighshire, Anglesey.
A review was prompted by records of two birds in 2006 and a recent paper on out-of-range pelicans in Europe (Ibis 150: 606-618).
The only record now retained in Category D is the bird observed at Hanningfield, Essex, and later at Fordwich, Kent, and the River Humber in July 1975.
Mugimaki Flycatcher Ficedula mugimaki
One record: Stone Creek, Humberside, on 16-17 November 1991.
Retain in Category D.
Unlike Brown Flycatcher, this species is known to have been in trade at the time of the occurrence. The Committee was unable to find compelling evidence of long-distance westwards vagrancy by this species.
There is some doubt about the provenance of the record from Treviso, Italy, on 29 October 1957, and the first non-controversial West Palearctic record involved an adult male seen near Neftekamsk, Russia, on 2 August 2007 (per M. Wilson).
Daurian Starling Agropsar sturninus
Two records: Fair Isle, Shetland, 7-28 May 1985; Durness, Highland, 24-27 September 1998.
Both records retained in Category D.
The two accepted Western Palearctic records (from Norway and the Netherlands) have both involved first-winter birds in autumn. This species is regularly found in trade, and there were concerns about the relatively early spring date of the Fair Isle record and the age (probably adult) of the Durness bird.
Red-headed Bunting Emberiza bruniceps
Formerly on the British List, this species was removed in 1968 on the basis that all records could have involved birds originating from trade.
There has still not been an acceptable record of an autumn first-winter bird, and this species was still in trade immediately prior to the record from Monreith, Dumfries & Galloway, 8-9 June 2004. Red-headed Bunting is reportedly still in trade in the USA, but any British occurrence which presents little overt reason to suspect captive origin following the complete ban on the importation of wild-caught birds into the EU (effective from 1 July 2007) will be looked at very seriously.
