美國白鵜鶘(Pelecanus erythrorhynchos)詳細描述與分類

這張圖片中的鳥類似乎是美國白鵜鶘Pelecanus erythrorhynchos),這是一種大型水鳥,以其純白色羽毛、巨大橙色鳥喙和**黑色飛羽(飛行時可見)**而聞名。


綜合描述:

  • 體型與外觀:
    • 是北美最大的鳥類之一,身長約 127–178 公分(50–70 英寸),翼展可達 240–300 公分(8–10 英尺)
  • 顏色特徵:
    • 全身呈白色,飛行時可見黑色飛羽。
    • 喙、腿部和腳部為鮮橙色。
  • 棲息地:
    • 喜歡淡水湖泊、緩流河流、河口和沿海沼澤地。
  • 行為:
    • 不同於棕鵜鶘(Brown Pelican),美國白鵜鶘不會俯衝捕魚,而是透過團隊合作,在水面上游動並用喙撈捕魚類。

分類(Taxonomy):

  • 界(Kingdom): 動物界(Animalia)
  • 門(Phylum): 脊索動物門(Chordata)
  • 綱(Class): 鳥綱(Aves)
  • 目(Order): 鵜形目(Pelecaniformes)
  • 科(Family): 鵜鶘科(Pelecanidae)
  • 屬(Genus): 鵜鶘屬(Pelecanus
  • 種(Species): 美國白鵜鶘(Pelecanus erythrorhynchos

這是一種候鳥嗎?

是的,美國白鵜鶘是一種遷徙性鳥類。

  • 繁殖季(夏季):
    • 主要分佈於加拿大與美國北部(如大平原、落磯山脈北部及加拿大草原省份)。
  • 冬季棲息地:
    • 遷徙至美國南部、墨西哥及中美洲過冬。
  • 遷徙經過德州:
    • 德州是牠們的重要中途停留點及越冬地,特別是在墨西哥灣沿岸、水庫及公園(如休士頓的Arthur Storey Park)。

由於這張照片拍攝於2月,這隻鵜鶘可能正處於越冬地,預計春季會返回北方繁殖地。

The bird in the image appears to be an American White Pelican (Pelecanus erythrorhynchos), a large waterbird known for its distinctive white plumage, large orange bill, and black flight feathers that are visible in flight.

Comprehensive Description:

  • Size & Appearance: One of North America’s largest birds, measuring about 50–70 inches (127–178 cm) in length with a wingspan of approximately 8–10 feet (240–300 cm).
  • Coloration: White body with contrasting black flight feathers (visible during flight). The bill, legs, and feet are bright orange.
  • Habitat: Prefers freshwater lakes, slow-moving rivers, estuaries, and coastal marshes.
  • Behavior: Unlike the Brown Pelican, which dives for fish, the American White Pelican feeds by cooperative foraging, scooping up fish while swimming in groups.

Taxonomy:

  • Kingdom: Animalia
  • Phylum: Chordata
  • Class: Aves
  • Order: Pelecaniformes
  • Family: Pelecanidae
  • Genus: Pelecanus
  • Species: Pelecanus erythrorhynchos

Is it a migratory bird?

Yes, the American White Pelican is a migratory bird.

  • Breeding Season (Summer): Found in Canada and the northern U.S. (e.g., Great Plains, Northern Rockies, and Canada’s prairie provinces).
  • Wintering Grounds: Migrates to the southern U.S., Mexico, and Central America during winter.
  • Migration through Texas: Texas serves as an important stopover and wintering ground, especially in areas like the Gulf Coast, reservoirs, and parks like Arthur Storey Park in Houston.

Since this photo was taken in February, the pelican is likely in its wintering range before migrating north in the spring.
