**頭頂的縱斑與台灣的區別**

學名: Garrulus glandarius brandtii
英名: Jay (Eurasian Jay)
Family: Carvidae (鴉科), Length: 33 cm.
是一種分佈極廣泛的鴉科動物，包括西歐大部分地區，至非洲的東北部，以至亞洲的東海岸以及東南亞等地均有分內。正因為分佈如此廣泛，因此不同地區的亞種往往出現極大的變異，特別是當它們的分佈地是相距極遠的時候，差異更大。在歐洲，松鴉也常被簡稱為Jay。常聽到松鴉的嗚叫聲多是粗糙刺耳的尖叫聲，主要是在發現捕獵者時用以警戒同伴之用。除此之外，這類型的鳥也擅長模仿其他鳥類的鳴叫聲。因此，除非能親愛看見，不然單憑聲音分辨容易被其誤導。有時甚至會模仿其捕食者的聲音以避過攻擊，如灰林鴞。松鴉好吃校欑籽，故日人叫松鴉為橿鳥。
The Eurasian Jay (Garrulus glandarius) is a species of bird occurring over a vast region from Western Europe and north-west Africa to the eastern seaboard of Asia and down into south-east Asia. Across its vast range, several very distinct racial forms have evolved to look very different from each other, especially when forms at the extremes of its range are compared.The bird is called jay, without any epithets, by English speakers in Britain and Ireland. Its usual call is the alarm call which is a harsh, rasping screech and is used upon sighting various predatory animals, but the Jay is well known for its mimicry, often sounding so like a different species that it is virtually impossible to distinguish its true identity unless the Jay is seen. It will even imitate the sound of the bird it is attacking, such as a Tawny Owl, which it does mercilessly if attacking during the day. However, the Jay is a potential prey item for owls at night and other birds of prey such as Goshawks and Peregrines during the day.
**頭部が茶色で、額から頭頂に黒い縦斑がある。顎線は黒い。頭上は白く、ごましお状の黒い斑がある。目の周りは黒い。両翼と尾羽は黒く、雨覆は白、黒、水色の奇麗な羽色である。それ以外は淡褐色。虹彩は白い。雌雄同色。樹林内の樹上や地上で採餌する。雑食性で、昆虫、クモ類、小型の脊椎動物、果実、種子、木の芽が多い。小鳥の巣を襲って卵や雛を食べることもよくある。樹林の鳥にとっては脅威の捕食者である。
