BCST recently published a new (draft) version of the checklist for
includes all new additions as well as taking into account a large
number of taxonomic developments resulting in a number of "splits"
and a few "lumps", all of which are explained in the accompanying
Some of the
most interesting developments, apart from recent
additions to the Thai Checklist, I will breifly mention here:
has been retained after genetic research.
& Rufous-backed Kingfishers have been lumped (again) as Oriental
Dwarf Kingfisher due to intermediate plumages and mixed pairs.
Two-barred Warblers have been lumped (again).
has been split into Rusty-cheeked Hornbill (Anorrhinus tickelli)
and Brown Hornbill (Anorrhinus austeni) based on genetic
Cucko has been split into Hodgson's Hawk Cuckoo (Hierococcyx
nisicolor) and Malayan Hawk Cuckoo (Hierococcyx fugax).
Leaf Warbler has been split into Kloss's Leaf Warbler and Davison's
has been split into Scaly Thrush and White's Thrush.
has been retained pending further investigation. I observed a group
of Rufous-fronted/Deignan's Babbler at Den Ya Kat, Doi Chiang Dao
in February 2008 and having been a sceptic as to the taxonomic stauts
of Deignan's Babbler, I noticed that there were easily recognisable
plumage and bill differences between these birds and most other
Plover remains lumped with Kentish Plover but it is expected that
it will be split at a later date.
It is stated
in the accompanying notes that this recently issued checklist is
only a draft and there are expected to be a large number of changes
in the not too distant future. Please go to the BCST's
website and take a look at both the checklist and the accompanying
