Thanks for the report, Sean. I have seen similar behavior. There was a House Finch nest in a basket hanging on our porch. Close by there was a House Sparrow nest in a neighbor's roof gutter, but it was knocked down and eggs/young destroyed during construction. So the male House Sparrow took over feeding the House Finch nestlings. And also aggressively fought the House Finches off whenever they approached the nest! At least in your case you have a easy going Robins rather than a tough male House Sparrow.
Best, Linda
