According to an anecdote, a Hungarian ornithologist was invited to give a lecture on his field in East Germany, and a Hungarian student who studied there was asked to interpret. The lecture started, the first picture was shown, with the following words: "This is a hoopoe with perching legs and a double-feathered crest that can be made erect or decumbent.” The explanation was followed by an awkward silence and after long, painful minutes, the interpreter started to speak: “Vogel!” (bird).

Such as Diana, with her Oreads seen / on swift Eurotas' banks or Cynthus' crest, / leading the dances. She, in form and mien, / armed with her quiver, towers above the rest, / and tranquil pleasure thrills Latona's silent breast.

Then, as with arms he comes to aid, they bind / in giant grasp the father. Twice, behold, / around his waist the horrid volumes wind, / twice round his neck their scaly backs are rolled, / high over all their heads and glittering crests unfold.

I think the crest on the top of the head of roosters is attractive.

Their breasts erect they rear amid the deep, / their blood-red crests above the surface shine, / their hinder parts along the waters sweep, / trailed in huge coils and many a tortuous twine.

The surfer tried to ride the crest of the wave.

Then he takes the crest, / the shield and dagger of Androgeus.
