“克服重重困难”
用英语怎么说？

Despite the joy the raven brings, biologists express concern regarding its long-term survival prospects. Some believe that leucistic ravens face an uphill battle, as white feathers are more fragile and prone to rapid deterioration than black ones, which contain melanin. However, specialists emphasize that survival is a daunting feat for any wild raven. The vast majority of these birds do not live to adulthood, frequently falling victim to predators during their nesting stage, or succumbing to starvation if a parent is lost. The wilderness is rife with unforeseen perils, making the white raven’s continued survival all the more remarkable. For now, the bird continues to defy the odds, thriving in the urban landscape and offering locals a compelling reason to venture outdoors during the bleakest days of winter, searching the skies for a rare flash of white.

尽管这只渡鸦带来了欢乐，但生物学家对其长期生存前景表示担忧。一些人认为白变渡鸦面临着一场艰难的斗争，因为白色羽毛比含有黑色素的黑色羽毛更脆弱，更容易快速退化。然而，专家强调，对于任何野生渡鸦来说，生存都是一项艰巨的挑战。绝大多数此类鸟类活不到成年，在筑巢阶段经常成为捕食者的牺牲品，或者在失去双亲之一时屈服于饥饿。荒野充斥着无法预料的危险，这使得这只白渡鸦的继续生存更加引人瞩目。目前，这只鸟继续克服重重困难，在城市景观中茁壮成长，并为当地人提供了一个在冬日最惨淡的日子里走到户外的引人注目的理由，在天空中寻找那一抹罕见的白色。
