Hmmm, I call those duck kisses. Mine will run to me and if I don't have a snack for them they will do a quick nibble and run away. I always thought they were saying hi and were trying to straighten my feathers. I say this because they will nibble at the seams of my jeans like they are trying to fix them.
Your foraging makes more sense though. I am a food source and that is how they get food from the mud. My version made it seem a sweeter thing.
