What's flying near you?

I'm certainly no ornathologist but a bird of prey, probably a sparowhawk methinks seems to have created it's own territory in the area I walk Kato. His territory seems to stretch for about 400 metres one way and maybe 100 metres the other way? I have no idea whether this is normal for this species,but he or she is certainly a joy to watch and I have nearly walked into a lampost or tree a few times watching it hover!
