Goose vs Swan
天鹅和鹅都属于家庭:阿纳那科和亚科:anserinae。因此,它们具有许多共同点,这提高了搜索它们之间的差异的兴趣。鹅在一个被称为部落的单独群体中:安塞里尼(Anserini),而天鹅属于部落:塞金尼(Cygini)。这些分类学差异具有明智的基础,这是它们独特的特征,这对于分别识别鹅和天鹅很重要。
天鹅
他们不是一群高度多样化的鸟类,and there are only seven species classified under the Genus: Cygnus. Cob and pen are the referred common names for a male and a female rspectively. They are the largest members of the family in terms of body size and weight, and wingspan. Swans’ wingspan could be as large as more than three metres with a body length of over 1.5 metres. The body weighs about 15 kilograms. Despite their massive bodies, swans fly long distances during migration. Characteristically long neck is one of their most prominent features, which distinguishes them from other wetland birds. Interestingly, both pens and cobs are similar looking, unlike in many other birds. They have simple plumage patterns with colours are varying from black to pure white. However, colourfulness is lesser in swans compared to other birds. Most of the swan species live in the Northern hemisphere are white (e.g. mute swan), while Southern hemispheric species viz. Black swan in Australia have a black plumage. Many of them are migratory, while the other species showing changing food preferences do not migrate fully. They have life partners for mating, but sometimes the pair does not live together. Usually, the cob helps the pen to make their nest to lay and incubate the eggs. During incubation, the pen takes more responsibility. The lifespan of a swan could range from 8 – 20 years in the wild, but there is a record of a 50 year old swan in captivity.

鹅是一组更多样化的解剖学,有22种真正的鹅在3属(Anser,驯化和灰色的鹅,Branta,Branta,Black Geese,Chen,Chen,White Geese)中。鹅的常见名称是男性的gand,女性的鹅。它们具有中距离体,这些物体的长度约为75 - 110厘米,重量为3-9千克,翼展约为1.5米。他们的脖子比鸭子长,但比天鹅短。鹅是五颜六色的鸟类,有时是戈斯林的金色羽毛。它们主要是草食性的,偶尔在饮食习惯中杂食。几乎所有的鹅种都是迁移的,在冬季寻求美食的过程中,它们在长距离飞行。他们是配对的纽带动物与强大的家庭单位。这些家庭不会分手,而是在整个迁徙期间保持在一起,只有在下一个繁殖季节,一岁鸽才会离开父母。雄性和雌性都孵化鸡蛋,在这段时间里,他们脱落了飞行羽毛,直到孵化器准备飞行之前,才会再生。 These interesting wading birds have about 24 years of lifespan in wild, and much longer in captivity.
天鹅和鹅有什么区别? •在三个属中,鹅的多样性高出22种,而只有七种天鹅在一个属下描述。 •男性和女性通常的名字分别是天鹅的柯布和笔,鹅和鹅在鹅中。 •棒子有助于笔制作巢,但不能帮助鸡蛋孵化。但是,甘德(Gander)在孵化期间有助于鹅孵化卵并互相保护。 •鹅拥有更强大的家庭单位,因为它们在长途悠久的距离上生活和飞行,而天鹅则没有那么牢固的家庭纽带。 •与鹅相比,天鹅的脖子更长,较大的翼展。 •天鹅不像鹅那样丰富多彩。 • Swans are either fully or partially migrating birds, whereas almost all the geese are migratory. |

差异很糟糕。从本质上讲,所有这些都是天鹅只是大鹅。本文列出了没有具体的分类差异。
