Until a couple of days ago I had only ever seen the Canada goose (Branta canadensis) grazing the grass on farmland in Cheshire and around Roath Park Lake or guzzling the offerings of generous humans, so it had never really occurred to me to wonder about what else they might consume. Now I find they are quite partial to aquatic vegetation like pondweed, horsetail, bulrushes and various reeds. This particular bird was not fussy as to preparation – it was a simple case of rip, roll, rinse, ruminate, repeat.
