A professional researcher should have a decent real camera at least. Trap cameras will register everything of that size in the area and can be set to register non stop for six months, so the excuse of "birds are afraid of us and fly" is not really solid.

Some cheap trap cameras are just too shitty to be useful. They just need to keep trying. But not a single good photo still, after decades of people trying to find it, carries a strong suspicion of extinction.
