The Family Ploceidae occurs throughout Eurasia and North America. They are primarily medium to large passerine birds. They are stocky, with strong legs and thick plumage. They have strong bills and webbing between their toes. Many species have brightly coloured halos around their heads. They are omnivorous, feeding on seeds, berries, insects and other small invertebrates. They nest on the ground, positioning their eggs close to the ground to avoid predators. The family is incredibly diverse, with over one hundred and fifty species. They range in size from the ten cm wholetail creeper to the seventeen metre Imperial eagle.
