Subject: Junkin's Warbler again
From: Doug Pratt <Doug.Pratt(AT)NCMAIL.NET>
Date: 10 Jul 2006 9:03am
Hi folks:
Laurent Raty's post is very helpful in this discussion. The hybrid
he mentions (Mourning x C. Yellowthroat) looks exactly like what one
would expect except for one thing: it has a white throat, unlike either
parent. This strengthens the case for Junkin's hybrid being a Mourning
x Canada. I still think Canada has to be one parent (too many details
not shared by any other species), but Mourning could easily be the
other, now that we know its hybrid combos may have white throats when
the other parent has yellow.

Hi all,
This message was posted on the birding-Australia website by Trevor
Ford via Tom Tarrant. I was wondering if anyone had any comments on
the matter.
Cheers for now,

Subject: [Birding-Aus] Minahassa Masked Owls
To: birding aus <birding-aus(AT)vicnet.net.au>
I'm posting this on behalf of Trevor Ford, please send all comments to me
and I will pass them on.
"I recently visited the Tangkoko reserve in Sulawesi with a friend, and we
were taken by a local guide to see their Minahassa Masked Owls. This
involved a walk to the beach and a boat ride of some 20 minutes, before
arriving at a small cliff face. The birds, presumably a pair, were together
in a hole less than 20 feet up the cliff. My friend was the first to express
doubts, noticing that they were far too big for the small Minahassa Masked
Owl, and that whilst one was rusty-coloured below, the other was pale. In
fact, entirely consistent with Sulawesi Masked Owl. Consulting available
literature, it would appear that Minahassa Masked Owl is a forest bird and
occurs from an elevation of 100 metres to 1,500 metres, not quite what we
were experiencing from our boat. An authority of the birds in the area was
shown photographs taken and is satisfied that they are Sulawesi Masked Owls.
But, according to our guide, these owls have been shown to visiting birders
for a couple of years, all of whom have happily 'ticked' Minahassa Masked
Owl. These visitors have included reputable bird tours with experienced
leaders. So what is the truth? Do we have a two-bird (or four-bird)
situation? I very much suspect not. Do we have a mass-hallucination
situation, based on every birders' natural desire to see a new and rare
bird? So much easier when you have had the bird identified for you and are
taken to see it! But surely the more experienced birders to have visited the
sight wouldn't have deluded themselves?
So, have you seen these owls and, if so, what did you think? Which
authoritative persons have identified these owls as Minahassas? It would be
good to uncover the real situation and learn how their identification was
established. I must admit to being a bit disappointed when it became clear
that we weren't going to add Minahassa Masked Owl to our list, although I
really enjoyed the experience of seeing a pair of tytos in broad daylight,
no matter what they were."

Subject: half yellow-billed tern
From: Albert Cama Torrell <albert_km(AT)HOTMAIL.COM>
Date: 15 Jul 2006 10:14am
Dear all:
13-7-06 we saw this tern at Tarragona, Catalonia, NE Spain.
We think it can be a sandwich x lesser crested hybrid. But our experience is
restricted with this kind of birds.

Any suggestion?

Subject: Greater Yellowlegs with orange-red legs
From: "Ian A. McLaren" <I.A.McLaren(AT)Dal.Ca>
Date: 15 Jul 2006 12:52pm
All:
A few days ago a colleague photographed a distant Greater Yellowlegs with
orange-red legs (not merely orange-yellow). It seems to me to be in limited
Alternate I plumage, with relatively unmarked gray mantle. The identification
seems secure - it has features that don't fit Spotted Redshank.
I've only been able to find (with an admittedly cursory search) three mentions
of this variant: Claudia Wilds' article in 1982, Birding 14, p. 172 (the source
quoted in "Birds of North America") and in Marchant et al.'s 1986 "Shorebirds .
. ."
Does anyone have personal observations or a primary reference to this?

Western Birds, Vol 30 (2), 1999. Report of the California Bird Records
Committee: 1996 Records
"Spotted Redshank Tringa erythropus. A Tringa seen at Winchester, RIV 28
Sep 1996 ...was reported to look like a yellowlegs but to have red legs. It
was never seen in flight or heard calling. Most Committee members felt a
record of such a rarity should be supported by a description that at a
minimum included the extent of the white on the back and rump."
Record rejected.

I should use the terminology of the Records Committee...not that the record
was "rejected" as to Spotted Redshank but that "record not accepted,
identification not established"

Hello Ian,
In spring 2004, I saw and digiscoped a Greater Yellowlegs with bright orange-red
legs in south-west New Hampshire;
http://www.keenbirding.com/2004/GtYellowlegs260504.html
It's the only such variant that I've come across.
