Hi!
I'm new at the forum and this is my first topic.
Alberto García Ríos and I visited Papua New Guinea in the summer of 2011.
On 2nd August, at Boystown road, near Kiunga, in company of our guide Edmund and his assistants, we saw and recorded on video a rather bizarre behaviour of Grey-headed Goshawk. At least I couldn't imagine such behaviour for a raptor. It perched upright on top of a tree and turned on itself while it was vocalizing and stretching vertically its wings in fast movements. We don't know if this was a territorial behaviour or a courtship display, but we didn't see any other individual nearby.
I've searched information about the Grey-headed Goshawk's behaviour, but I've found nothing special for this species in the bibliography I've consulted. I've searched papers through google without success, but I don't know if it is the best way to search papers.
We would like to know if the described behaviour is already known.
You can see the video at:

Kind regards,
