A good case study on extinction is the Passenger Pigeon.

It was in the nineteenth century one of the most abundant birds, with some estimates at 5 billion birds. However, by 1914, the last one had died in a American zoo.

Why the sudden decline? Hunting. It was commercially hunted for its meat. Since they flew in huge flocks (millions of birds) they were easy targets.

Deforestation also contributed to their decline.
