hardly a good flyer, at least
in the long run. Unfortunately it
flight inferior is not only graceful
flight all subspecies of Black Cockatoo that
due to a longer tail
wings and tail of the latter, but is inferior
the flight of these small subspecies such as Pink,
Small and long-billed, which can
to fly for a long time, making a uniform
a strong and vigorous strokes. Large
same Jeltuhay Cockatoos usually fly
uncertainly, making asynchronous
the strokes, i.e. for example one stroke, then
a pair of consecutively, like the nervous
strokes, then attempt to soar, but if
the air is not sufficiently warmed up,
asynchronous flapping again with
a different frequency, then
some part of the way the bird still soars
and the sequence of movements of the wings
povertetsya again. This is what concerns
flight over long distances. But when
we are talking about flying from tree to tree,
or from rock to rock, or from one
high buildings on the other, the picture
radically changing. Here Large
Jeltuhay Cockatoo irresistible
assy! They excrete striking
turns and pirouettes,as if playing fly
sideways, and with the coup, and doing other
incredible aerial stunts! It should
see! Especially gives effect tricks
expand, culminating
there’s a huge bright yellow crest!
Who watched at least once such
acrobatic air show, will
struck by the beauty of these turns! Especially
it’s exciting when the scene becomes
freeway passing between the high
trees. It seems another instant and the bird
get caught for speeding multi-ton
the truck…

that they can head
scream. However, it is not in their Arsenal
there are a huge number of sounds,far
not always drastic, it is and whining
during courtship, and meow during
communication, and how to be a Sizzling mumbling,
common to each case its tone
and volume. But as a rule sharp cries
during the flight (as if for roll call
and also scare away lizards or other
enemies), haunting observers
. A voice was heard upon
large distances. Can
to emit a whistling and gurgling sounds.


The first half of the day
