| 1. |
These
birds are often regarded as pests because of their
diets (sometimes feeding on crops); licensed culling
is permitted in certain states. |
|
|
| 2. |
Both parents take part in incubating the eggs. |
|
|
| 3. |
Cockatoos can mimic the sounds of other animals,
including people. |
|
|
| 4. |
Cockatoos
can hold their food in one foot and break pieces
off of it with the other foot. |
|
|
| 5. |
Cockatoos
live in small loose flocks. |
|
|
| 6. |
They
are very gregarious and quickly learn to mimic.
These birds also have a very shrill cry. |
|
|
| 7. |
These
birds are thought to be one of the rarest parrots
on Sumba Island. In 1993, studies estimated citron
populations to be 1,150-1,850 individuals. |

Cockatoos
are a food source for many animals larger than
themselves.
Their
feeding habits are very destructive, which annoys
most gardeners.
Cockatoos
aid in seed dispersal through their eating of
fruit.
Citron
cockatoos are not common in the pet trade, due
to difficulties with successful breeding programs
and they are not as popular as other cockatoo
species.
The
U.S. Wild Bird Act forbids the commercial import
of any bird listed by CITES which includes most
parrots - endangered or threatened.
