ok\n Hoatzin chicks have archyopterix-style claws on their wings\n\nPuffin`s beaks are not as colourful out of the breeding season\n\nThe Goatsucker (no, not el Chuppacabra, the bird!) of the USA is called a Nightjar in the UK\n\nAmerican Robins are not related to european Robins, they are in fact a type of thrush\n\ncormorants have to open their wings to "dry" them as they`re not as waterproof as other waterbirds.

They are birds. \nThey lay eggs.

One of its feet are both the same.

This seems like a facetious question, but here's a whack at an actual answer. The Egg. Here's why: the actual chicken genus and species is for sure derived from a common ancestor with other birds and fowl, diverging through genetic (and morphological) changes over time. At some point, the "ancestor chicken" produced an offspring that would for all intents and purposes be insdistinguishable from what we now know as a "chicken" but was the offspring of a demonstrably different (but probably very similar) animal.

Another way of putting that would be \n"birds of a feather flock together" \nI think that basically says the same thing, don't you?

the chromosomes group together.

a uniting -joining together

they are *extremely* different kinds of plants, so the only similarities would be that their flowers have petals, stamens and ovaries

Swans and ducks belong to the same family (Anatidae) but different subfamilies. \n\nSwans belong to the subfamily Anserinae. Some of their characteristics are: \n- Long neck\n- The plumage lacks metallic colors or a speculum (patch of conspicuous coloring in the wings)\n- No sexual dimorphism (males similar to females); also the calls of both sexes are similar\n- A single annual molt (after breeding)\n- Monogamous, they form life-long or long-lasting couples, and both male and female care for the chicks,\n- This is not so easy to see, but the pattern of scales on their legs is reticulate\n\nSubfamily Anatinae (typical ducks):\n- Most species with a speculum on the wing, with metallic colors\n- Most with sexual dimorphism: usually the males are more "gaudy" and their voices may be different\n- The males have sexual parades different from the females, and in many species the plumage of the male during the breeding season is very noticeable, but they have an -\ninconspicuous non-breeding plumage (which means that they undergo 2 yearly molts)\n-The males usually do not participate in incubation or care for the chicks,\n- Different pattern of leg scales\n\nAnd in case you were wondering, the geese are also Anserinae. \nNot all ducks are Anatinae. The whistling ducks belong in their own subfamily, the Dendrocygnini, and their characteristics are somewhat more similar to the swans than to the "typical ducks".

The male bird is usually brighter color.

I can assure you that this is absolutely not biologically possible.  Members of different species cannot reproduce and produce viable offpsring together, according to the classical definition of a species.

Yes, they go together.

They must have escaped from someone - they are not native to America.  They may have been adopted by the starlings, so they will probably survive. They don't usually live in such cold climates though. Help them by feeding them through your bird feeder.  Just out of curiosity what colour are they???

Yes.  Consider dogs, which are all considered to be the same species.  Yet, it would be difficult to cross a Great Dane with  a Yorkshire Terrier (no silly jokes about stepladders please - this is Science!!).  Because of th edimorphism, these are effectively two different species - often called "Ring species".  You can look that term up on the web.
