My daughter-in-law has no especially strong interest in birds and didn't notice the eye colour.
In respect of Maurits' final point,however, she did notice there was no last hurried flapping of wings - the bird appeared to deliberately walk under the car's wheel.

For what it's worth I see that Wikipaedia reports that [as well as dogs] "ducks, have also drowned themselves. One duck did so after the death of its mate".

One of the saddest things I saw many years ago was on the Boorowa to Frogmore Road where in pouring (and I mean really pouring rain) a thoroughly bedraggled galah was sitting perfectly still beside its dead mate on the edge of the road.

I don't think we should dismiss this out of hand either. Corvids, and other birds, have strong pair bonds, and if this bird saw its mate being hit by a car, and was sufficiently distraught, I don't see why it wouldn't step in front of a car.

I have seen Rosellas standing by the body of a dead mate beside the road, presumably grieving,

I believe that the observation should not be dismissed out-of-hand.  We do tend to anthropomorphise the world around us and impute actions onto other creatures which are highly unlikely or even impossible.  If this observation had involved any other type of bird, the answer would be a categorical 'no'.  Corvids, however, have managed to surprise us on many occasions with their intelligence (and it's unfortunate that suicide is the domain of the intelligent). 
 
There are many animals which, when they feel that their time is nigh, remove themselves from their pack or herd to die quietly somewhere.  Elephants are known to mourn and grieve their dead relatives, and dogs have starved themselves to death when their owners die.  So it is not crazy to suggest that an intelligent creature like a raven would be aware that it is ailing and that it is 'time to go' without that instinct requiring that it knows what death is.  It would, however, set a precedent, as suicide is practically unknown outside the realm of humanity.  Lemmings don't rush off cliffs, pilot whales don't beach themselves in an concerted effort to end their lives, and the aforementioned dogs don't starve themselves so that they can be reunited with their owners in heaven.
 
Ravens are also extremely savvy when it comes to motor vehicles.  They are the least likely of all birds to be run over, even though they love to hang around on the edge of roads for the prospect of road-kill.  They would have seen many other animals fall victim to cars, so would know what would happen if they got in the way of one.
 
Finally, we have the (naturally subjective) opinion of the observer, although the raven must have been acting unusually in the first instance for it to have gained the observer's attention.
 
Taking all of this into consideration, we could be conditioned and say that it was a young and inexperienced, short-sighted or hungry raven, but maybe, just maybe, this was one which knew that it was time to die and knew that getting hit by a big beastly car was a quick way to go.  After all, a bird can hardly end its life by jumping off a high-rise building!
 
The accuracy of the observation is the key.  Like the case of the dog in the night, it hinges on how the raven reacted in the final instant before the car bore down on it.  If there was  no last hurried flapping of wings, then it knew what it was doing.  If there was, then it was all just a bad mistake.

I think the raven just got momentarily distracted by a tasty morsel or something else.

 

A friend of mine told me she saw a Kookaburra pounce on a Willie Wagtail that had been harassing it for years. The Wiilie dropped down onto the ground for a tasty morsel and the kooka dropped down straight after it, took it back up onto a branch, pounded it against the branch and swallowed it. Was the Willie tired of living? I don’t think so.

While quite intelligent, Birds are a bit far down the evolutionary tree to have the brain structures required for the kind of emotions, self-reflection and world view associated with the kind of self-planned suicides that humans sometimes demonstrate. At the level of birds we have a range of associative learning styles, from trial and error, associative and (in bigger birds at least) imitation. This bird appears to have taken the Avian Darwin Award for this year, bring an end to whatever association had developed in its neural network which initiated this particular action. Other birds which use walking out into traffic as a way of successfully cracking nuts are clearly on a more adaptive evolutionary track!

Sounds quite significant behaviour considering a pub out Yanco way had a standing prize of a slab of ale for anyone who ran over what all would call a Crow. I understand the prize has never been claimed.

My daughter-in-law told me of a strange incident last week in a busy part of Civic.

There was a raven standing close to the side of the road who spent about five minutes carefully and intently watching every car go by.
Eventually it walked calmly out just as a car came up, timing it such that the driver could not avoid killing it.

Does anyone have any likely explanation?

Thanks, Brian
