This thread is dedicated to the general discussion of flora and fauna found by FlyerTalk members during their travels all over the world.

For example, one observation I have noticed is that whether I travel to major cities worldwide, such as Buenos Aires, Tokyo, Paris or New York, the pigeons seem to be exactly the same species. Are they really the same, or are there subtle differences I simply am not noticing? Are there any other species of flora or fauna found throughout the planet that are indeed the same?
