The extinction of passenger pigeon was due to 

  1. increased number of predatory birds.

  2. over exploitation by humans.

  3. non-availability of the food

  4. bird flu virus infection.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The passenger pigeon or wild pigeon (Ectopistes migratorius) is an extinct species of pigeon that was endemic to North America. Its common name is derived from the French word passager, meaning "passing by", due to the migratory habits of the species. The scientific name also refers to its migratory characteristics. The morphologically similar mourning dove (Zenaida macroura) was long thought to be its closest relative, and the two were at times confused, but genetic analysis has shown that the genus Patagioenas is more closely related to it than the Zenaida doves. The main reasons for the extinction of the passenger pigeon were the massive scale of hunting, the rapid loss of habitat, and the extremely social lifestyle of the bird, which made it highly vulnerable to the former factors. Deforestation was driven by the need to free land for agriculture and expanding towns, but also due to the demand for lumber and fuel. Though there are still large woodland areas in eastern North America, which support a variety of wildlife, it was not enough to support the vast number of passenger pigeons needed to sustain the population.  As the flocks dwindled in size, the passenger pigeon population decreased below the threshold necessary to propagate the species.

So the correct option is 'over exploitation by humans'.
