Did anyone posek that penguins are (non)kosher?
Well, the same question might be regarding the swans.
The Sonchino edition Talmud Bavli, Chullin 62B says:
"R. Huna said: Bunia is permitted parwa is forbidden"
And in the footnotes:
"The penguin and the sea mew respectively."
How do they know that bunia is the penguin indeed? (Did our sages even saw penguins?)
