企鹅意识日

让我们行动起来，一起投入到企鹅意识日的活动中去吧！你能说出多少种企鹅的名字？今天的照片展示的是敏捷的马可罗尼企鹅在智利德雷克海峡浮游生物丰富的水域中畅游的场景。这些迷人的生物只是在南半球发现的18种企鹅中的一种，可以通过它们奇特的橘色装饰性羽毛和突出的橙色喙来识别。马可罗尼企鹅成群结队地觅食，但雄性企鹅之间会相互攻击。为了表现出和气和避免打斗，个体通常会把头缩在胸前，这样就可以轻松地穿过企鹅群。尽管企鹅深受人类的喜爱，但近年来食物的减少、渔网的误捕，以及气候变化对其栖息地海冰的深刻影响，都对企鹅的生存构成不小威胁。

Penguin Awareness Day

Let's flap our flippers and dive into Penguin Awareness Day! Today's image features macaroni penguins swimming in the plankton-rich waters of the Drake Passage off the coast of Chile. These charming creatures, one of 18 different species of penguin in the Southern Hemisphere, can be recognized by their flashy amber crests and orange beaks. The name is said to have been coined by English sailors, derived from a term used to describe flamboyant dressers in the late 18th century.

Macaroni penguins can be a bad-tempered bunch who get into noisy fights. To avoid this, males often ease their way through crowded colonies with their heads tucked down to their chests. The main threats though, are not their fellow penguins. Reduced food availability, fishing nets, and the impact of climate change on sea ice are among challenges faced by this species, which has been classified as vulnerable due to population decline.
