FaecesThe waste product from the alimentary system, expelled through the cloaca along with the urine, which is produced by excretion from the kidneys. The faeces forms the dark part of a bird dropping. Faecal analysis can be useful in studying the food of birds but as in pellet analysis it over-emphasises the intake of food items with hard indigestible parts.
