When Catesby visited the Bahamas in 1725 he would have seen flocks of flamingo. It was unusual for him to depict an isolated part of a creature, and the structure of the flamingo’s beak clearly interested him. He recorded that ‘Nature has provided the edges of their Bill with a Sieve, or Teeth, like those of a fine comb’, which allow flamingos to filter muddy particles out of their food.
