Like the proverbial pigs, these Mallards looked at home and happy rooting in the mud at low tide on the North Basin. Mallards are omnivores. Grass, seaweed, seeds, fine. Aquatic worms, snails, larvae, fine. Whatever, bring it on, and they don’t mind getting neck-deep in mud to find it.
This pair seem to be permanent residents here, although I’ve yet to see evidence of a nest or chicks. They nest on the ground, so safety from predators has to be high on their list of concerns.
