The American Redstart is a strikingly colorful warbler native to North America. Adult males are predominantly black with vivid orange patches on their sides, wings, and tail, complemented by a white belly. This vibrant plumage not only makes them easily identifiable but also plays a role in their unique foraging behavior. By flashing their bright tail and wing patches, males can startle insects from foliage, making them easier to catch. allaboutbirds.org
These birds are highly active insectivores, often seen hopping among tree branches in open woodlands and forest edges. Their diet consists mainly of insects, which they skillfully capture in mid-air or glean from leaves. During the breeding season, male American Redstarts establish and defend territories, using their vibrant plumage and melodic songs to attract females. en.wikipedia.org
In terms of size, the American Redstart measures approximately 4.3 to 5.1 inches (11 to 13 cm) in length, with a wingspan of about 6.3 to 7.5 inches (16 to 19 cm). Their energetic behavior and distinctive coloration make them a favorite among birdwatchers and a fascinating subject for ornithologists studying avian ecology and behavior. allaboutbirds.org
美洲紅尾鶲 (Setophaga ruticilla)
美洲紅尾鶲是一種原產於北美的色彩鮮豔的林鶯。 成年的雄鳥主要為黑色，兩側、翅膀和尾部有鮮明的橙色斑塊，腹部為白色。 這種鮮豔的羽毛不僅使牠們易於識別，還在其獨特的覓食行為中發揮作用。 通過閃爍明亮的尾部和翅膀斑塊，雄鳥可以驚嚇樹葉中的昆蟲，使其更容易被捕捉。
這些鳥類是高度活躍的食蟲者，經常被看到在開闊的林地和森林邊緣的樹枝間跳躍。 牠們的食物主要是昆蟲，牠們能夠在空中巧妙地捕捉，或從葉子上拾取。 在繁殖季節，雄性美洲紅尾鶲會建立並保護領地，利用其鮮豔的羽毛和悅耳的歌聲來吸引雌性。
在體型方面，美洲紅尾鶲的長度約為4.3到5.1英寸（11到13厘米），翼展約為6.3到7.5英寸（16到19厘米）。 牠們充滿活力的行為和獨特的色彩使其成為觀鳥者的最愛，也是鳥類學家研究鳥類生態和行為的有趣對象。
