The Eurasian chaffinch, scientifically known as Fringilla coelebs, is a small passerine bird belonging to the finch family. Measuring about 14.5 cm (5.7 inches) in length, this bird is characterized by its vibrant plumage, particularly in males, who display a striking black forehead, blue-grey crown, and pinkish to rust-colored face and breast. Females are more muted in color, featuring a greenish-brown appearance that aids in camouflage.
This species is widespread across Europe and parts of Asia, thriving in wooded areas, gardens, and farmlands. The Eurasian chaffinch is known for its melodious song, which varies regionally and plays a crucial role in the bird's mating rituals. Young chaffinches learn their songs by mimicking adult males during a critical learning period after hatching.
Eurasian chaffinches are generally non-migratory in milder climates but will migrate from colder regions during winter. They often form loose flocks outside the breeding season and are commonly seen at garden feeders. Historically, these birds were popular as caged songbirds, leading to significant trapping practices that have since been curtailed by conservation laws[1][2][3][4].
歐亞花雀（學名：Fringilla coelebs）是一種小型雀形目鳥類，屬於雀科。這種鳥的體長約14.5厘米（5.7英寸），以其鮮豔的羽毛而聞名，尤其是雄鳥，牠們擁有醒目的黑色前額、藍灰色頭冠，以及粉紅色到銹紅色的臉部和胸部。雌鳥的顏色較為樸素，呈現綠褐色外觀，有助於偽裝。
這個物種廣泛分布於歐洲和亞洲部分地區，在林地、花園和農田中茁壯成長。歐亞花雀以其悅耳動聽的歌聲聞名，其歌聲因地區而異，在求偶儀式中扮演著重要角色。年輕的花雀在孵化後的關鍵學習期通過模仿成年雄鳥來學習歌唱。
歐亞花雀在氣候較溫和的地區通常不遷徙，但會在冬季從較寒冷的地區遷移。在繁殖季節之外，牠們經常形成鬆散的群體，常見於花園餵食器旁。歷史上，這些鳥曾是受歡迎的籠中鳴禽，導致大規模的捕捉行為，但現已被保育法規所限制。
