  1. Many birds, including species of gulls, raptors and ducks, undergo a change in eye colour as they age from juvenile to adult. This is likely an adaptation that helps these birds recognise maturity and therefore suitability of a potential mate.
  2. Lorikeets are parrots, but they are not grain eaters, they are nectivores. 
  3. There are many bird species that grip food with their feet, but only the parrot holds their food with their feet to their beak while they eat. 
  4. The Buff-Faced Pygmy Parrot that can be found in New Britain and New Guinea, is the smallest specie of parrot in the world, at about 3 inches (7.5cm)
  5. Many species of Parrots are monogamous, meaning that they live out their life with only one mate. 
  6. The Kakapo Parrot is a nocturnal flightless bird that weighs up to 7 pounds (3.2kg), making it the heaviest parrot in the world. 
  7. The Kakapo Parrot is one of the rarest parrot species in the world, with 126 known birds left in the wild.
  8. The beaks of parrots are used for a wide range of functions (eating, breaking nuts, exploring their surroundings, grooming), therefore their beaks are extremely strong. Some of the larger species of parrots are able to break open the hard shell of a Brazil nut. [The Parrot biting force is measured from 300 psi to 2000 psi. Whereas humans have a biting force of 150 psi]
  9. Most parrot species lay an average of 2-8 eggs per clutch. Where both the male and the female parents take turns sitting on them. They take approximately 18-30 days to incubate. And will not start to develop feathers until about 3 weeks after hatching
