Black-billed Magpies are noisy birds with a habit of sitting conspicuously at the tops of trees or fenceposts, making them easy to hear and see. That is exactly why I noticed them in a parking lot along I-70 in Colorado.
The Black-billed Magpie (Pica hudsonia) is a large, highly intelligent bird belonging to the corvid family (which includes jays, crows, and ravens) and is native to the western half of North America. Known for its striking black-and-white plumage and boisterous personality, this social bird is easily recognized by its long tail and distinct, swaggering strut. They are generally non-migratory. They are opportunistic omnivores that consume insects, seeds, grains, wild fruit, carrion, and small rodents.
黑嘴喜鵲是一種喧鬧的鳥類，習慣顯眼地棲息在樹梢或柵欄柱頂，因此很容易被聽到和看見。正因如此，我在科羅拉多州 I-70 公路旁的一個停車場裡注意到了它們。
黑嘴喜鵲是一種體型較大且極具智慧的鳥類，屬於鴉科（成員包括松鴉、烏鴉和渡鴉），原產於北美洲的西部地區。這種群居性鳥類以其引人注目的黑白羽衣和活潑喧鬧的性情而著稱，憑藉其修長的尾羽以及那種獨特、大搖大擺的步態，人們極易將其辨認出來。它們通常不遷徙。它們是機會主義的雜食動物，以昆蟲、種子、穀物、野生果實、腐肉及小型囓齒動物為食。
