No wonder the name Northern Shoveler with a bill like that.
Female Northern Shoveler Duck dedicated to her nest.day in and day out on a patch of grass under a tree between a busy road and a pond . I travel the road multiple times daily. I never saw her off her nest , nor did I see a male around. She must have taken breaks from time to time. I was a bit surprised she chose a spot so close to a very busy road.
