The waters surrounding Shooter's Island have long been a dumping ground for ruined ships and boats, and the wreckage there has caused these waters to be exceptionally still. ██ █████████████ █████ ████ ███ ███████ █████████ ██ ██████████ ██████ █████████ ██████ ██ ███████ ██ ████ ██████ ████ ██ ███ ███████████ ████████ ███ ████ ████████ ██████████ ███ ████ ████ ████████ ██████ █████████ ██████ ████ ██████ █████ █████ ████████ ████ ████████ ████ ███ █████ ██████ ██████ █████████ ██████ █████ ██ █ ███████ ███ ███ ██████████
The author hypothesizes the abnormally still waters surrounding Shooter’s Island act like a nursery for juvenile waterbirds. Why? Because those waters have roughly as many total waterbirds as waters around nearby islands, but many more juvenile waterbirds.
The author assumes there’s a higher proportion of juvenile waterbirds around Shooter’s Island because the still waters act as a nursery, and not for some other reason. This means assuming adult waterbirds prefer to raise their young in still waters, perhaps because still waters offer some benefit to the development of juvenile waterbirds.
