Columbidae

Pigeons and doves constitute the bird family Columbidae that includes about 310 species.

Pigeons are stout-bodied birds with short necks, and short, slender bills with fleshy ceres. They feed on seeds, fruits, and plants. This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones.

In general, the terms "dove" and "pigeon" are used somewhat interchangeably. Pigeon is a French word that derives from the Latin pipio, for a "peeping" chick, while dove is a Germanic word that refers to the bird's diving flight. In ornithological practice, "dove" tends to be used for smaller species and "pigeon" for larger ones, but this is in no way consistently applied, and historically, the common names for these birds involve a great deal of variation between the terms. The species most commonly referred to as "pigeon" is the rock dove, one subspecies of which, the domestic pigeon, is common in many cities as the feral pigeon.

Doves and pigeons build relatively flimsy nests – often using sticks and other debris – which may be placed in trees, on ledges, or on the ground, depending on species. They lay one or two eggs at a time, and both parents care for the young, which leave the nest after seven to 28 days. Unlike most birds, both sexes of doves and pigeons produce "crop milk" to feed to their young, secreted by a sloughing of fluid-filled cells from the lining of the crop. Young doves and pigeons are called "squabs".

Kurt Cobain

Kurt Donald Cobain (February 20, 1967 – c. April 5, 1994) was an American musician who was best known as the lead singer, guitarist, and primary songwriter of the rock band Nirvana. Cobain formed Nirvana with Krist Novoselic in Aberdeen, Washington, in 1985 and established it as part of the Seattle music scene and grunge genre. Nirvana's debut album Bleach released on the independent record label Sub Pop in 1989.

After signing with major label DGC Records, the band found breakthrough success with "Smells Like Teen Spirit" from its second album Nevermind (1991). Following the success of Nevermind, Nirvana was labeled "the flagship band" of Generation X, and Cobain hailed as "the spokesman of a generation". Cobain, however, was often uncomfortable and frustrated, believing his message and artistic vision to have been misinterpreted by the public, with his personal issues often subject to media attention.

During the last years of his life, Cobain struggled with heroin addiction, illness and depression. He also had difficulty coping with his fame and public image, and the professional and lifelong personal pressures surrounding himself and his wife, musician Courtney Love. On April 8, 1994, Cobain was found dead at his home in Seattle, the victim of what was officially ruled a suicide by a self-inflicted shotgun wound to the head. The circumstances of his death at age 27 have become a topic of public fascination and debate. Since their debut, Nirvana, with Cobain as a songwriter, has sold over 25 million albums in the U.S., and over 75 million worldwide. Cobain was posthumously inducted into the Rock and Roll Hall of Fame in 2014, along with Nirvana bandmates Novoselic and Dave Grohl, in their first year of eligibility.
