3rd September decisions
At the 3rd September 2012 meeting of the Records Committee, the following decisions were agreed.
Red-crested Pochard 2012-03-09. Previously accepted as a first-year female, it was unanimously agreed to place this record into Category I, the first record of this species considered to have occurred naturally. Previous records continue to be regarded as of non-natural occurrence.
Grey-necked Bunting 2012-04-10 in Sai Kung. Previously accepted as an adult female, there was a 3-3 split between placing this species in Cat I and Cat III. In such cases, it is RC policy to adopt the more conservative approach, and to remain with the status quo. Should further records occur in the future, this can be reviewed.
Features counting against Cat I included the unusual tail feather placement visible in photographs and the date, which was considered early for a bird presumed to have flown from wintering grounds in northern India; the distance from there to HK is probably longer than the distance from northern India to Central Asian breeding grounds, and it is reasonable to expect occurrence in HK no earlier than the time it begins to occur on the breeding grounds (mid April). Although it is possible to postulate this was a bird that spent the winter in southeast Asia, there is no evidence that the latter occurs regularly, and the chances of such a bird arriving in HK are considered slim. Although there is a record from Vietnam in winter, we have no idea of the provenance of that bird. Furthermore, occurrence in spring is contrary to HK records of other species that winter in India, which generally occur in autumn. The only other regional record of a vagrant occurred in autumn in Japan, which is typical of other comparable species such as Black-headed and Red-headed Bunting, and Common Chiffchaff.
All-dark storm-petrel 2012-05-30. By a 5-1 vote, the RC accepted this record as that of an all-dark Storm-petrel sp, probably Swinhoe’s although it was not possible to eliminate Tristram’s or Matsudaira’s, based on the photographs.
Russet Sparrow: after a review of photographs, all 2011 records are considered likely to involve ex-captive individuals. Given this and after a review of all previous records, there was unanimous agreement that this species should now be placed in Category III.
Although no further decisions affecting the HK List were made, work is continuing on the following species:
Pale Blue Flycatcher: a review of category.
Brown Shrike of the taxon confusus: a review of possible records based on published criteria.
Rufous-bellied / Rufous-vented Niltava: a review of records.
Blue-fronted Flycatcher: a review of all records in regard to both identity and category.
‘Grey-cheeked Fulvetta’: work still underway regarding which species occurs in HK, and the most appropriate category.
