|
| 1. |
The
bills of Derbyan parakeets are designed to nest
in tree cavities that woodpeckers have previously
dug out. |
|
|
| 2. |
Their markings are great for camouflage among the
trees. The green and black feathers are perfect
in matching them with the sun shining through the
trees. |
|
|
| 3. |
These parakeets are very noisy and are often spotted
in flocks of about 40 individuals. |
|
|
| 4. |
There
are several different color variations between subspecies
that depends on distribution. |
|
|
|
| |
|
|
|
Because
these parakeets have fast digestive systems, the
fruits, berries, and other seeds they eat help
to disperse the seeds. This in turn propagates
the plant life in the rainforest.
These
birds are protected but not threatened other than
by pet trade. The U.S. Wild Bird Act forbids the
commercial import of any bird listed by CITES
which includes most parrots - endangered or threatened.
