Adaptations on Budgerigars


This term Ava and I wrote an information report on the adaptations of a budgerigar. This is the report.

Budgerigars and also known as the common parrot, are green and yellow native birds to the Australian dessert. They have been adapting and living in Australia for over 5 million years.



  1. Budgerigar’s feathers are able to absorb water so they can go longer periods of time without water.
  2. They are brightly coloured (yellow and green) so the sun light reflects off of them so they can stay cool and so they can camouflage in the more greener trees.
  3. They fly in big groups or flocks so they don’t get eaten by predators.
  4. They are able to fly for long periods of time to look for food and water.
  5. They eat lots of dry food to stay hydrated


One of the main adaptations of a budgerigar is its colours. Its bright green and yellow help it camouflage in the wild. They also have a very flexible tongue that allows them to eat seeds and nuts whole. A way they stay cool is their feathers can soak up moisture from the dew in the mornings.  Budgerigars can maintain a small size around 18 – 20cm so they can camouflage better and so it is harder for predators to catch them.


To stay cool budgerigars will bathe in damp grass and will drink up to 5.5% of their body weight daily. To make sure they drink that amount of water they will try to locate themselves near dams, rivers and other water sources. To make sure they are always near a source of water they migrate all year round. This means they do not build nest as they are always leaving and following where the water goes. They will nest in hollow logs and trees. Their flocks can range from 3 – 100 birds. They use these flocks to protect each other by confusing predators like the Australian hobby and butcherbirds by flying in many different directions very fast.

Key adaptations

The key adaptations for the survival of the budgerigars is the way it migrates all year round. This is crucial to its survival because if they don’t migrate they will die of thirst. This adaptation has lead them to adapt the way they nest. They have adapted to nesting in hollow logs trees instead of building nest.  Building nest has become a waste of a budgerigar’s time so using hollow logs and trees means they can spend more time looking for water


They can live in cold and coastal environment and they can even live in dessert
Some areas in the dessert can be very hot and that can lead to budgerigars to die.
Budgerigars are never found in Tasmania, cape York and coastal areas of east and
north Australia.


for our science experiment we used different coloured tubes full of water and put them in the sun to see if the colours kept the budgerigar cool. These are the Results.

Adaptations – the process of change by which an organism or species becomes better suited to its environment.

Camouflage – hide or disguise the presence of (a person, animal, or object)

Moisture – wetness caused by water

Predators – an animal that naturally preys on others

Water sources – is a place that stores or has water

Migrate – an animal that moves from one region or habitat to another according to the seasons.

Flocks – a number of birds of one kind feeding, resting, or travelling together
