The only other really cool one I’ve got is that occasionally (like it’s only been reported a handful of times sort of thing), they will use an abandoned nest in a tree. These are really big nests, like from bald eagles, so plenty of space for both parents (bald eagle nests are large enough to hold 3-5 human toddlers fairly comfortably).

Bald eagles typically nest along waterways as well, so overhanging nests are an interesting opportunity. I rather assume the goslings just jump out into the water, but I honestly don’t know if their tiny bodies would survive the fall onto regular ground. Probably would, they weigh almost nothing.
