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.

 

Death or illness can be the direct result of insensitive observation of your mated stock. For example, I had a cinnamon sky hen given to me by a frustrated fancier that killed two cocks in my attempts to set up pairs with her. A local Champion suggested that I put her in a cage with several cocks and allow her to choose. The idea worked like a charm in less than an hour. She was on eggs within a week with a live mate for the first time in four years.

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.

 

One effect of social stress is that some birds, especially hens, will eat too much in a competitive feeding aviary scene. The solution may be to isolate these individuals in flights within sight & hearing of the flock but without the driving force of physical competition reduced. An accurate battery powered scale is a very useful tool in monitoring a bird’s weight. Most fanciers are adept at judging how the bird feels in the hand, but actually weighing the bird and tracking its weight would be more useful in the long term especially to a beginner.
