There are about 310 species of pigeons. Several are endangered. The passenger pigeon, which numbered from 3.5 to 5 billion, was hunted to extinction in about 80 years. The common Rock Pigeon (that we see in most large cities) does not even number 200 million, but is not at risk of going extinct.
The Socorro Dove is extinct in the wild (pigeons and doves are the same order and family, but different species. E.g., the common city pigeon, the Rock Pigeon is actually the Rock Dove); the Victoria Crowned Pigeon is Near Threatened (classification on the path to extinction); the Negros Fruit Dove, the Silver Pigeon and the Sulu Bleeding Heart remain with less that 50 in existence. There are a number of other pigeon species that have less than 500 individuals still alive.
The reasons for extinction are almost always related directly to mankind, in the destruction of habitats and hunting.
Passenger Pigeons became endangered through overhunting and habitat loss.
Southern Crowned Pigeons are not endangered, though their population is decreasing.
The main difference is that passenger pigeons are extinct. Also, regular pigeons now are much less attractive in color that passenger pigeons were.
It's possible that scavengers like foxes and raccoons would have benefited from a continued presence of passenger pigeons due to the abundance of food. Similarly, certain bird species that may have relied on the pigeons as a food source or for nesting sites could have also experienced changes in their populations due to the extinction of passenger pigeons.
Peregrine Falcons are the most threat for your pigeons.
Passenger pigeons would fly in large flocks in Wisconsin and other states in the 1800s.
The passenger lived in the forests of eastern North America.
Messenger pigeons are domesticated Rock Pigeons,Columba livia domestica, that are trained to fly and return to humans. Passenger pigeons were a wild species.
Ectopistes Migratorious.
