The
most important principle or activity in keeping any animal in captivity
is to reduce stress experienced by the captive. The sources of this
stress can be categorized for the convenience of discussion as: Environmental,
Dietary, Social, Genetic and Disease. Stress from any source is totally
and completely cumulative on the well being of the captive and as
such is only categorized for the convenience of discussion and resulting
management options. The use of aviary techniques to reduce stress
can actually prevent a disease organism that is latent in the flock,
from developing by promoting or allowing natural resistance to prevail.
This is a very powerful result beyond the reach of our antibiotic
culture.
Most veterinary discussions about animal care focus
on disease as the source of stress. This clinical discussion, while
especially useful in individual pet care, is far too narrow to be
completely useful to the animal keeper managing a large group of animals.
The focus of this article will be on allaying problems whose source
can be found in all areas of stress generation: Part three will cover
some areas of Social Stress. Environmental Stress and Dietary Stresshas been at least partially covered in previous articles.
Genetic
Stress and Disease Stress will be covered in later articles. The discussion of
animal care and management from the perspective of cause not symptom
has been very useful to me over the years, as it is far easier to
manipulate potential sources of stress than second-guess symptoms
caused by some cumulative group of stresses. This approach involves
making management changes then listening to your flock for any change
in chatter.
Implicit in the focus of this method is that veterinary
care of individual birds, however effective, is not the procedure
of choice in maintaining a large flock of breeding birds. Stated another
way, any bird that succumbs to a major disease (chronic or catastrophic)
is lost to the breeding program even if it survives, so prevention
is the only effective path for the group.
Social Stress Defined:
If
the company one keeps is not tolerant and kind, one’s well-being can
be in jeopardy. Our personal solution may be to leave and take a trip
(vacation, divorce) but if one is a caged captive, one must stay and
take the consequences of the nagging, mental torture or out right
violence.
Budgies are very sociable and do not hide their intent. This is a blessing to you the keeper; just take the trouble to observe without anthropomorphizing.Overcrowding is an obvious source of social stress. An 18” perch is really crowded with three occupants so it is easy to figure the capacity of a cage or aviary.
Some authors talk about visually isolating dominant
cock budgerigars so that the neighboring less dominant cocks are not
sexually suppressed. While this effect is very important in many species
of birds, I don’t think that it is necessary in the case of breeding
the very social, communal budgerigar. Visual sight barriers are helpful
around the nest box hole to reduce the stimulation of pugnacious hens.
