My neighbour Niven feeds our local birds. Now this kookaburra visits me when I put out the laundry.
“Kookaburras kill snakes,” Niven said as he placed small chucks of minced meat on the wall. Kookaburras, magpies, and some others (maybe butcherbirds and plovers?) swoop down. So the idea is that if they’re around, maybe the snakes will decide not to be.
Great thinking Niven!
