Nikolas ... Did you mean "27th December 2012" or did you mean "Raja and I are
going to observe a...." ;-)
Hi Vivien,
Graeme Chapman actually discussed that bird on the link that you posted Vivien,
which is available on the Birding-aus archives. See:
http://bioacoustics.cse.unsw.edu.au/archives/html/birding-aus/2012-11/msg00039.html
There are some other places for you to research suggested by him as well. I
haven't tracked down the Leo Joseph book that he mentions, but it sounds like a
great read.
Of interest, HANZAB says that "Evidence of hybridisation equivocal" and goes on
to cite some examples where the evidence wasn't quite strong enough to be
unequivocal, one of which was described by McGill when a male White-browed and
a female Masked had a nest with eggs but the "pair was collected before the
eggs were allowed to hatch"!!
I also recall seeing a photo of a potential hybrid taken by someone at...Bowra
maybe?
See also the link below for another bird very similar to one on Graeme's
website.

Hi Vivien,
Raja
and I observed a White-browed/Masked Woodswallow hybrid 27th December 2013
at Whoey Tank, Round Hill, NSW (Eremaea/Birdline NSW #160543). I am pretty sure
that Raja has some pictures of this bird. They are not yet uploaded to the
website but we will have a look for them and make them available.
Best wishes,
Nikolas

Hi,
Yesterday 15th of october at Campbell Park (ACT) there was a group of 30+
White-browed and 5 Masked woodswallows in which I found a peculiar bird which I
now think is a male White-browed/Masked woodswallow hybrid.
The bird was perched quite low together with 2-3 White-browed Woodswallows and
I could see it for about 30 seconds. It had bright rufous underparts (like a
male White-browed Woodswallow) and a black eye/face/throat mask (like a male
Masked Woodswallow). There was a thin white line around the black mask that
turned into a thicker white band on its upper chest creating a neat contrast
with both black and rufous parts.
I only have HANZAB vol. 1 so far - still looking for all the other ones so if
you want to sell them contact me in private! - so I couldn't check whether it
mentions Woodswallow hybrids.
I therefore turned to the internet - always dangerous, I know!
Photo 544204-D at
http://www.graemechapman.com.au/library/viewphotos.php?c=576displays a bird
similar to what I saw yesterday (top bird obviously).
I am interested in information about woodswallow hybrids so I turn to
experienced Australian birders out there.
How common are Woodswallow hybrids? How much variation do they show? Are there
confirmed observations of female hybrids?
Thanks a lot for your help!
Cheers,
Vivien Rolland (Viv)
