This has posted, and discussed, to HN in the past.<p>From the article: "According to the team, firehawk raptors congregate in hundreds along burning fire fronts, where they will fly into active fires to pick up smouldering sticks, transporting them up to a kilometre (0.6 miles) away to regions the flames have not yet scorched."<p>... where "according to the team" means "we have not actually filmed or photographed this behaviour, once, despite years of trying".<p>I wish them the best of luck; it would be fascinating to learn of animals other than humans using fire as a tool.<p>But for now, it's still firmly in the "old bush legend" category.
