I've seen similar behaviour to that being discussed with White-winged
Choughs. I assumed it was some type of mating display when i saw it.
Here's a photos i got of the display that might help people visualise
whast being discussed here:

[Birding-Aus] Corvid Behaviour
I was outside of my house the other day when I noticed a T. Crow at
the back of a property across the street with its wings spread. That
was not something I could recall seeing before, so I popped inside to
collect my binoculars.
I initially thought the bird was caught on something and hanging down,
but it moved and I was able to see that it had both its wing and tail
feathers fully spread - the effect reminded me a bit of the posture
assumed by riflebirds. It held that attitude for a few minutes before
being approached by another crow and they both dropped out of sight.
Is that wing & tail spread position typical of corvid mating display
behaviour?
Regards, Laurie.
