The name “Pigeon Forge” comes from an iron forge built by Isaac Love (1783–1854) sometime around 1820. The name of this forge referred to its location along the Little Pigeon River, in the vicinity of what is now the Old Mill. The name of the river comes from the flocks of passenger pigeons that frequented its banks at the time of the first Euro-American settlers’ arrival.[4]

So they are now extinct:
[P]igeon meat was commercialized as a cheap food for slaves and the poor in the 19th century, resulting in hunting on a massive and mechanized scale. A slow decline between about 1800 and 1870 was followed by a catastrophic decline between 1870 and 1890.
Interesting — As went slavery declined so did the passenger pigeons they ate or vice versa.
