The possible answers are "yes" and "no". I would be surprised if there is a generally correct answer to this. I would be surprised if any more than very few species would always answer the same, let alone most species. I would be very surprised at a option of abandon the nest for ever after. The birds using a site may be the same two individuals, one of the pair, or 2 new birds, so tracking memory is difficult. It also depends a lot on how easy it is to find a new nest site. Surely the answer is different for hollow nesting species (such as gang gangs, for which a good tree hollow is likely to be used again) to those that build a stick nest in a tree (such as goshawks) which is probably not in short supply. Raptors are inclined to use the same nest or tree or general area over a series of years. Whether they are more likely to change partners or to change site or neither, after a failure is a big question with surely many answers. But predation is a constant risk.

Hi all I was wondering what people's thoughts were on the topic of birds returning to nest sites if they loose chicks at that nest in the previous year. Would the parents return the following year to try again if the nest is a good one ?. Or would the parents abandon the nest for ever after ?. 

I ask because last year I had my goshawks chicks taken by a predator as well as my gang gangs. I am wondering whether they will return this year to try again. If they do I would like to metal collar there nest trees to stop the predation from cats and goannas again.
