[Tweeters] Feral vs. Wild Rock Pigeons

This is quoted from Cornell’s Birds of the World data base:
"Introduced to North America in the early 17th-century by colonists who brought domestic pigeons to Atlantic coast settlements (Schorger 1952a <https://birdsoftheworld-org.access-proxy.sno-isle.org/bow/species/rocpig/cur/references#REF38328>), the Rock Pigeon (formerly the Rock Dove) is now feral and lives broadly on the continent. Wild Rock Pigeons, native to Europe, North Africa, and western, southwestern, west-central, and southern Asia, gave rise to domestics as a result of artificial selection by humans (Darwin 1868 <https://birdsoftheworld-org.access-proxy.sno-isle.org/bow/species/rocpig/cur/references#REF29297>). Domestics readily go feral, and have done so widely throughout the world (Long 1981 <https://birdsoftheworld-org.access-proxy.sno-isle.org/bow/species/rocpig/cur/references#REF18984>).”
It would appear that it is never appropriate to use Rock Pigeon (Wild type) on an eBird checklist for a North American location, even if you see a wild population living on cliffs. That would explain why, when you make a species map in eBird for Rock Pigeon (Wild type), no records exist for North America. eBird shows Wild type sightings mostly in Iceland, the UK, most of the countries bordering the Mediterranean, the Near East, Middle East, and India. They would still be Rock Pigeon (Feral Pigeon) on this continent.

> Years ago, when we lived in Denver, Colorado. I watched some Rock Pigeons at the Red Rock Amphitheater. They all looked like the original wild Rock Pigeons with no color variations, even though they were likely from feral stock. They sure looked like they were in their natural habitat! Not to date myself, but if I correctly recall, they were not "countable" at that time. Now the Magnificent Frigatebird I found, was a first for the Colorado list!

If you want to report a wild type, you have to add a species to the checklist and select Rock Pigeon (wild type). That is considered a rare bird. But how are we to determine what is a feral pigeon and what is a wild type Rock Pigeon? There is no guidance in eBird that I can find. When should we consider using the wild type category and what evidence of a rare pigeon sighting would eBird reviewers want to consider when deciding whether to include the report in the public data?
