Bustards are large and highly terrestrial birds mainly associated with dry open country and steppes in the Old World. They range in length from 16 to 59 in. They make up the family Otididae. Bustards are omnivorous and can live and thrive in variable environmental conditions, and sustain itself from a number of different food sources (opportunistic).

Bustards are all fairly large with the two largest species, the Kori bustard and the Great bustard, being frequently cited as the world's heaviest flying birds.

Bustards are omnivorous, feeding principally on seeds and invertebrates. They make their nests on the ground, making their eggs and offspring often very vulnerable to predation. They walk steadily on strong legs and big toes, pecking for food as they go. Most prefer to run or walk over flying. They have long broad wings with "fingered" wingtips, and striking patterns in flight. Many have interesting mating displays, such as inflating throat sacs or elevating elaborate feathered crests.
