The underwing has corresponding sets of coverts (the names upperwing coverts and underwing coverts are used to distinguish the corresponding sets). In addition, the front edge of the wing is covered with a group of feathers called the marginal coverts. Within each group of wing coverts, the rows of feathers overlap each other like roof tiles (the greater coverts are overlain by the median coverts, which in turn are overlain by the outermost row of lesser coverts, and so on).

A US wind energy company was ordered to pay $8m in fines after pleading guilty to killing at least 150 bald and golden eagles at its wind farms.
A wind farm with so-called “industry-leading” bird avoidance technology has killed at least eight endangered Tasmanian wedge-tailed eagles, prompting calls for an urgent moratorium on new turbines in eagle zones.
