The passenger pigeon existed in vast flocks, migrating from place to place in search of food, mainly nuts and seeds, fruits. The birds refused to nest unless there were large numbers of birds in the colonies, and this may have eventually doomed them as the numbers plumetted from hunting pressure. Young fledged birds were left on the breeding grounds, and formed their own dense flocks.
The cat was responsible for killing the dodo birds. it was taught that the last group of dodo birds lived around a lighthouse it was soon found that the cat had eaten every dodo bird left. but it was only one.
Passenger pigeons were hunted by natives as a source of food. Here are several ways the natives hunted the passenger pigeons:killing the juveniles at night with long polessetting up large nests to capture the adult pigeonslow flying pigeons could be killed by throwing sticks and stonesCherokees killed pigeons by throwing their club at the leading pigeon in the morning when it left its roost

Passenger pigeons died out mostly because they were so abundant that they were hunted on a massive scale to provide inexpensive meat for slaves and the poor. Eventually, this overhunting combined with habitat loss due to extensive settlement of the West led to their extinction. The last known passenger pigeon, named Martha, died in 1914. Passenger pigeons were mainly a bird of eastern forests, and were slaughtered on their breeding grounds for food. There were still plenty of forests left for them to exist, but as the numbers dwindled, the birds sometimes refused to nest, seemingly requiring huge numbers to stimulate the breeding rituals.

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.
If 4 birds flew away from the fence, then 5 birds would be left on the fence.

Passenger pigeons, now extinct, were a member of the dove family. They were once the most numerous bird on the planet with flocks numbering in the billions. People hunted them for food. As the demand grew, teams would follow the flocks from place to place, not giving them time to nest By the late 1890's, hunting ceased because the few thousands that were left had scattered and it was no longer worthwhile to hunt them. But the birds disappeared because as colonial nesters, they needed large flocks to breed or they didn't try to nest. The last one recorded in the wild was in 1900, the last one on earth, "Martha", died in an Ohio zoo in 1914.
There are four birds left
In America and other countries where you drive on the right side of the road, the passenger side is the right side. In countries where you drive on the left side of the road, such as England, the left side is the passenger side.
