Birds (advertisement) "Birds" is an award-winning television commercial for the Washington Lottery; it won a Silver Lion at the 2009 Cannes Lions International Advertising Festival, and "Best in Show" at the 2009 National ADDY Awards. "SHOOT" magazine placed it on their Top 10 list for Summer 2008. First broadcast in June 2008, it depicts three flightless birds—a penguin, a chicken, and an emu—being taken hang-gliding (the chicken and the penguin are shown wearing harnesses strapped to the chest of the glider pilots; the emu's harness
Ratite as a whole probably had an origin in the northern hemisphere. Early Cenozoic northern hemisphere paleognaths such as "Lithornis", "Pseudocrypturus", "Paracathartes" and "Palaeotis" appear to be the most basal members of the clade. The various ratite lineages were probably descended from flying ancestors that colonised the south in multiple waves, probably initially in South America, and then evolved gigantism. Loss of flight allows birds to eliminate the energetic cost of maintaining flight-enabling pectoral muscle mass. The basal metabolic rate of volant species is much higher than that of flightless terrestrial birds. But energetic efficiency can only help explain the loss
