（单词翻译）
This disused car park is a near-perfect location for raising chicks, and only a short flight from a plentiful1 supply of food. Skimmers get their name from their unusual feeding technique--their extended lower bill detects fish just below the water surface.
The heavy use of east coast beaches by people has threatened skimmer numbers. It’s
ironic2 that this man-made car park made out of crushed
oyster3 shell should become a substitute.
Skimmers raise their chicks on a fish diet. But they serve their portions whole which can cause problems for their young.
The increasingly human landscape of North America can make wildlife spectacles a rare event. But there are situations when it brings nature closer to people. That’s exactly what has happened here in this power plant in Florida. These are West Indian
manatees4, residents of the Florida coast. People and manatees don’t usually get along. Increasing boat traffic has become a big threat to manatees and some bear the scars of painful encounters with boat
propellers5.
