Happy #WorldSeabirdDay!
Today commemorates the #extinction of the #GreatAuk (Pinguinus impennis), a large flightless #seabird in the #alcid family that lived in the North Atlantic and was hunted to extinction in 1844. Let's #celebrate, #conserve and #protect our extant seabirds!

pennisetum ペンニセツウム、道端などでよく見かけるチカラシバの一種。イネ科の植物だけれど、食べることも出来ず、引き抜くにはかなりの力を要することからチカラシバの名前がつく。子どもの頃は、穂先をちぎり取り「毛虫」などと呼んで遊んだことが誰にもあるんじゃないだろうか。
