They should be looked for on dry lakebeds throughout the region. Chicks are
usually noted from early May through June, and occasionally into July and
August. Small numbers are seen during some winters at Edwards AFB and China
Lake.

Subject: Mystery Bird Updates
From: Trevor Hardaker <trevor(AT)DHK.CO.ZA>

Greetings from Cape Town,
Just a quick update on the two most recent mystery birds on our website at
http://www.zestforbirds.co.za . They are either too easy or too difficult
judging from the lack of comments so far. However, there have been a few
people that have sent us comments. So far, the verdicts are:
Mystery Cuckoo #2: There have been two options suggested here. The bird is
thought to be either an African Cuckoo (Cuculus gularis) or a European
Cuckoo (Cuculus canorus). There have also been suggestions that it is the
hepatic form of the European Cuckoo.
Mystery Gull #6: The 3 suggestions for this bird are more or less equally
divided. They are Kelp Gull (Larus dominicanus dominicanus), Cape Gull
(Larus dominicanus vetula) and "Baltic" Lesser Black-backed Gull (Larus
fuscus fuscus).
So, put your thinking caps on and send us your verdict on these birds. We'd
love to hear what you think they are and what your reasons for saying so are
as well.
Looking forward to hearing from you.
Kind Regards
Trevor and John

Hi all,
You may find interesting the pictures on my
site of an unusual Turdus sp. I appreciate
any insights and comments from all of you
on these birds....have a look at:
http://www.angelfire.com/ca5/pelagics/MYSTERIES2.html
There is no music so it shouldn't crash your
browser, no matter how antiquated :):):)
I apologize for problems some viewers have
had. I guess I'll de-embed the music, so you
have to click on it to get it, and eliminate
the problems....
There is a Myiarchus and an Oystercatcher on
the page as well....
all of us are smarter than any of us

Subject: Green-winged Teal
From: Angus Wilson <wilsoa02(AT)ENDEAVOR.MED.NYU.EDU>

For those who haven't seen it already, there is a paper in the current
issue of British Birds reviewing the systematics of the Green-winged Teals
(Anas carolinensis and crecca).
The citation is:
Sangster, G., Collinson, M., Helbig, A. J., Knox, A. G., Parkin, D. T. and
Prater, T. (2001) The taxonomic status of Green-winged Teal Anas
carolinensis. British Birds 94: 218-226.
The article appears to be a formal announcement by the Association of
European Rarities Committees and the British Ornithologists' Union Records
Committee that they now consider Green-winged Teal (A. carolinensis) and
Eurasian Teal (A. crecca) separate species. The authors provide an elegant
summary of the morphological, behavioural and molecular differences between
these two forms, which are in general culled from existing literature. It
is also well illustrated with color photos showing salient points for field
identification of males and, perhaps more importantly, the very similar
females.
The most recent molecular analyses can be found in:
Johnson, K. P. and Sorenson, M. D. (1998) Comparing molecular evolution in
two mitochondrial proteins coding genes (cytochrome B and ND2) in the
dabbling ducks (Tribe: Anatini). Mol. Phylogen. Evol. 10: 82-94.
Johnson, K. P. and Sorenson, M. D. (1999) Phylogeny and biogeography of
dabbling ducks (genus Anas): a comparison of molecular and morphological
evidence. Auk 116: 792-805.
Interestingly, Sangster et al. find little support for the Aleutian
subspecies A. carolinensis nimia described by Friedmann in 1948, and imply
this population is not distinct from A. crecca.
One wonders whether the American Ornithologists' Union (AOU) will follow
this re-split? Can anyone with in-side knowledge comment? Perhaps records
committees in North America might want to encourage observers to submit
records of "Eurasian Green-winged Teal", in anticipation of a future split
on this side of the pond?

Subject: Median Coverts in Gulls
From: Jean Iron <jeaniron(AT)SYMPATICO.CA>
Date: 15 Jun 2001 12:34pm
Do gulls have 1 or 2 rows of median secondary coverts on the upper wing?
The reason for asking is that Jean Iron and I did a molt study of the
Heermann's Gull that spent about 10 months in Toronto, Ontario from
November 1999 to September 2000. We'll be submitting a paper to Ontario
Birds, which describes the Alternate I and Prebasic II molts of Toronto's
Heermann's Gull.
The Heermann's Gull allowed us to study its plumages and molts at extremely
close range. Our observations suggest that it had 2 rows of median coverts,
overlapping in the opposite direction (inner webs exposed) to the greater
coverts and to most of the lesser coverts. We asked two museum people. One
examined a Ring-billed Gull wing which appeared to have 2 rows; the other
examined a Great Black-backed Gull wing which also appeared to have 2 rows
of median coverts. In specimens feathers often become disorganized, hence
the qualifiers "appeared" to have 2 rows. There seem to be 2 rows of median
coverts in a few good flight photos in Grant's (1986) Gulls.
In the excellent article on upperwing topography on page 230 in the June
2001 issue of Birding, it says that "By convention and to be unambiguous,
the greater and median coverts are best considered to each consist of a
single row of feathers." What is the "convention" being referred to in the
Birding article?
Are there 1 or 2 rows of median coverts in gulls?
Happy gull watching,
