The green owl who was the logo of language-learning app Duolingo is no longer. The US company behind the app, which became a household name during the Covid-19 pandemic, has issued an announcement revealing that its cute cartoon owl has died.

Duo the Owl was known for his silly antics, reminding Duolingo users to complete their daily lessons. He debuted with the app in 2011.

PITTSBURGH (KDKA) — The Duolingo Owl is dead, according to a statement from the Pittsburgh-based company. "It is with heavy hearts that we inform you that Duo, formally known as The Duolingo Owl, is dead," the language learning app posted on social media Tuesday morning.
