In this video, a bird is plucking fur from sleeping Labrador Retriever, Maple.
The owners of the dog said that they had filmed at least three times that the bird flew down to pluck fur from their sleeping dog. It lasts only a few minutes, and then the bird flies back to pad her nest with the fur.
The dog occasionally wakes up, but doesn’t seem to mind. This may not be a common practice for birds, but we hope it’s somehow a symbiotic relationship.
