Omniscient, you're correct about the OP. My error, I was caught up in the swirl of the variety of assumptions (other than the ones accounted for in OP) by subsequent posters.

But I still say one needs to limit geography (brown tree snakes in Guam as opposed to native range); and time frame, too: komodo dragons had predators (a larger varanid) - they just happen to be extinct now.

Pigeons are predated upon by falcons and hawks, and as these raptors expand into the cities... So the time frame works both directions. Although:

Pigeons, most of our barn cats have brought down full grown, healthy pigeons,
don't they have stray cats in the city anymore?
Apparently the growth of Szechuan restaurants and chicken nuggets has escaped notice.
