You're forgetting something. The population in the protected areas goes up dramatically before the shooting season even begins.
Ducks migrate.
Ducks that are not dead always return to their nesting areas. Dead ducks tend to stay away.
This doesn't answer the question. Firstly, ducks nest in the spring and not in May , which is late autumn when the duck-shooting month is. Secondly, the vast increase in the duck population in protected areas lasts only for this month. Once the shooting season is over the visiting ducks return to their own feeding habitats and stay there until late April of the following year. Please note that I'm not claiming that the entire duck population of New Zealand displays this behaviour, only that a statistically significant proportion of them do.

I didn't realise you were fluent in the duck tongue. Animal behaviourists say different.

In less than a few minutes about 7 or 8 ravens had gathered around the body but they didn't seem to be doing much of anything except shuffling about gently from foot to foot. They weren't completely silent but they weren't their normal raucous and noisy selves either. Their vocalisations were something I'd never heard before and the closest I could get to describing it would be as a low-pitched "mumble". They didn't touch or peck at the body but rather just formed a rough circle around it. I didn't think to time how long all this took but I'm sure it would have been no more than a few minutes before they all took off simultaneously and headed off in different directions. It was a truly bizarre sight and one I'll never forget because bird behaviour is a subject of great interest to me.
And to what do you attribute this behaviour.
What sort of bird?
I don't attribute this behaviour beyond the probability that it is what it appears to be, a ceremony of some sort. The bird was a raven and in all likelihood a family member because they congregate in extended family groups, usually numbering between 8 and 14.

This is not what happened in the incident I witnessed and I've not read of this happening generally. Perhaps you could provide a reference for this claim because it is not typical of corvid behaviour. None of the assembled birds touched the body at all and they all flew away together. I didn't stick around to see what subsequently happened to the cadaver but I'd be willing to bet that it would have been another species of carrion-eater that got the free feed.
