Apologies if what follows has already been addressed.  There are two vicious
strains of flu circulating in Canberra, and five days after recovering from
the first, I cam down with the second, and so have been out of circulation.

Apparent errors in the 1996 Supplement to James F.Clements' Birds of the
World: A checklist, Fourth Edition,1991 in Birding, Supplement to
Birding,Vol.29,No.3,pp.92-93, and a query about the AOU Supplement.

p.174.  add Golden-crowned Sapphire.
Surely this should read Golden-crowned Emerald.  Alll members of the genus
Chlorostilbon are known as Emeralds.  The preceding species in Clement's
list, Blue-chinned Sapphire, is Chlorestes notatus.
Also Howell & Webb, p.403, refer to the species as Golden-crowned Emerald.

p.386  Change English name of Cinnycerthia peruviana...
should read Cinnycerthia peruana...

p.444 After Southern Black-Tit...
should read  p.445...

and scientific name from Viridonia sirens
should read
 and scientific name from Viridonia virens

p.533 after Red-winged Blackbird add:
Cuban Red-winged Black-bird
Agelaus assinalis

The Latin name should read Agelaius assimilis
Also the AOU Supplement (p.548) gives the English name of this species as
Red-shouldered Blackbird.

I also query the AOU's decision (p.548), which reads as follows:
p.681.The The species Atlapetes(or Buarremon) atricapillus,Black-headed
Brush-Finch, is merged with the South American B.torquatus, Stripe-headed
Brush-Finch, following Wetmore et al.(1984). An account for the combined
species replaces that for atricapillus.

Ridgely & Tudor, 1989, The Birds of South America: the Oscine Passerines,
Vol.1, pp. 436-437, retain A.torquatus and A.atricapillus as distinct
species, and comment in a Note on p.437:

...we retain this expanded atricapillus [ie.taking in the form
costaricensis] as a species distinct from A.torquatus (contra
Wetmore,Pasquier and Olson), for the ranges of these approach each other
very closely in Colombia (though habitats may differ) with no apparent
evidence of intergradation.

I would have thought that the AOU should have followed the more recent
authority.  If they have still more recent evidence (eg if Ridgely has
recanted in a personal communication), they should have cited it.  In the
absence of such evidence, I am going to follow Ridgely and Tudor in my list!
