What If…?

Portraits of Christopher Columbus and passenger pigeons (public domain via Wikimedia Commons)

This year’s remembrance of the passenger pigeon is, for me, inextricably linked to Christopher Columbus.

Last year I read a book that generated that association.  1491: New Revelations of the Americas Before Columbus describes what North America was like before and after Columbus’ arrival.

Before Columbus, the human population in the Americas was larger than Europe’s and the landscape, animals and birds were balanced by the pressure of so many people.  Europeans arrived and accidentally left behind pigs carrying human disease.  Native Americans, who had no immunity to European disease, encountered the free-range pigs and spread the plagues through human contact.

The Western Hemisphere suddenly lost 95% of its human population in only 150 years.  Remove the keystone species and you get some pretty weird results.  European settlers didn’t see the transformation so they thought what they found was normal including the endless forest, huge bison herds and billions of passenger pigeons.

So I wonder …

If Native Americans had not died off, would passenger pigeons have boomed at all?

If there hadn’t been so many passenger pigeons, would we have hunted them to extinction?

What if?

  1. I’m not a bird expert, but I’m pretty sure I see a bird that looks just like that painting outside my window all the time. Could it be a very similar one or is it just not as extinct as we thought? It’s not like we can truly scan the whole world to know they are extinct.

    1. Antonella, several living birds are similar to the extinct passenger pigeon but they aren’t the same thing. In the eastern U.S. mourning doves and Eurasian collared doves are similar. In the west, white-tipped doves, white-tipped doves and band-tailed pigeons are similar. In fact, the band-tailed pigeon is so similar that some people suggest recreating the passenger pigeon in the lab by altering the genes of a band-tailed pigeon. … But no, they aren’t the same.
