The seeds pictured below fall around my neighbourhood every Autumn (Southern Hemisphere - New Zealand). The seeds are blown over quite a vast area and I haven't been able to identify the tree(s) they're coming from (possibly on private property where I can't get near).
I suspect they're either sycamore or maple seeds but Google Images show them to both look very similar. I was hoping someone might be able to give me a more definitive suggestion.
