By Dr Rob Marshall B.V.Sc., M.A.V.C.Sc. (Avian Health)
His book, The Budgerigar is no doubt the most extensive book to be written on the subject of the Budgerigar since Gerald Binks’ published The Challenge. While the focus of The Challenge is more on the Exhibition Budgerigar, The Budgerigar, by Dr. Marshall, contains astonishing detail on Budgerigar health and disease and contains information essential for keeping Budgerigars, especially in the development of exhibition bloodlines.
Based in Sydney Australia, Dr Rob Marshall has over 30 years experience treating dogs, cats and birds. He is a world renowned bird veterinarian and has a passionate interest in many bird species.
There are countless successful feeding systems and the choice depends upon the time and resources available to the fancier; although the methodical and most fastidious fanciers invariably enjoy the greatest success. Fresh foods or specialised feeding systems enjoy the equal success. A regular time of feeding is especially important. A routine that closely resembles the wild bird activities is particularly beneficial for the health and well being of aviary budgerigars.
The aviary budgerigar still retains the gregarious flock patterns of its wild forebears, thriving on feeding activities that include the whole flock. Feeding in large trays, providing interesting seeding grasses and eucalypt baths in the early part of the day invigorate the whole flock into a frenzy of activity, not from hunger but from a deeper instinctual need. Psychologically the birds are much happier which in turn promotes a stronger physical well being.Soaked seed techniques are potentially hazardous to the aviary budgerigar and are best replaced by specialized nutritional recipes. Trays of fresh bread soaked in nutritional additives are quickly accepted when they are provided as part of this community routine. Cleanliness and hygiene are paramount to the successful feeding system.
Clean Food and Water
In the wild, the budgerigar selects recently fallen seeds and the seeds at the top of the grass first, because these are the most nutritious. Fresh clean seed is also imperative for a successful breeding season and health in the aviary. This fact can never be overstated.
- Fresh, clean food is the starting point for a healthy and successful breeding season.
- The protection of the food from contamination during storage is the next important step.
- Spoiled seed is the most common cause of poor breeding performance and recurrent illness in the budgerigar aviary.
- It is impossible to cure illnesses and poor breeding results when “bad feed” is the underlying cause of such problems.
- Food cleansers are used to keep the food in storage fresh and clean by protecting it from mould, yeast and other harmful agents.
Trace Elements
The most important trace elements for breeding budgerigars Iodine, Iron, Copper and Zinc.
A deficiency of any trace element will decrease breeding performance. Iodine is the most important trace element for breeding. Trace element supplementation is best given in the water or soft food mix during the breeding season.
Iodine activates the metabolism of budgerigars and is used to stimulate the aviary into breeding condition, to accelerate the moult of young birds and to “peak” the birds for the show. An audible whistling or squeak indicates iodine deficiency. Iodine deficiency tends to be a regional problem. Several reliable iodine supplements are available.
Vitamins for the Budgerigar
The modern day exhibition budgerigar is much larger and has a greater feather mass, grows more slowly and requires more energy and nutrients to develop. When the vitamins and minerals are not provided, the breeding birds tire easily becoming more susceptible to illnesses and the babies weaken. Although budgerigars can survive on grain and grit alone, they cannot reach the level of health required to withstand the pressures of breeding and eventually their breeding performance and health fails.
The vitamins lacking in the seed must at some stage be given to the birds in some form or other. Vitamins are a necessary part of budgerigar life and nowadays vitamins are given in the soft food mix or water. All of the B vitamins, especially Thiamine, accelerate the recovery of ill birds by reducing stress. The signs of a vitamin deficiency in the budgerigar are subtle. Often the vitamin deficiency relates to a bowel infection and can be confused with an illness.
Vitamin A is a particularly important vitamin for the budgerigar. Seeds are particularly low in vitamin A, vitamin A promotes appetite, digestion and also increases resistance to infection and to some parasites. The signs of a deficiency are subtle, but look carefully at the feather colour intensity, the cere colour and condition. The feathers are pale, rough and lack lustre, the cere roughened not smooth, and there may be an accumulation of a yellow dry scale on the sides of the mouth in budgerigars with a vitamin A deficiency. Look for signs of bumble foot and scaly face mite, which are both thought to be associated with vitamin A deficiency. The most obvious sign of a vitamin A deficiency is a feather stain above the cere. The staining of the feathers above the nostrils reflects a discharge from the nostrils. As with all of the other vitamin deficiencies birds with a vitamin A problem respond quickly to the supplementation of the vitamin in the water. Within three days the feathers colour up and shine again and the birds become erect and alert. Vitamin A supplements are helpful in stimulating the appetite of overcrowded young and breeding birds.
Vitamin D3 is produced by natural sunlight and has an intimate relationship with the calcium metabolism. Calcium is vital to fitness and vitality through its role in muscle and bone health. Vitamin D3 is incredibly important for egg laying, strong babies and vitality in the young birds and breeding flock but an excess of vitamin D causes kidney damage and retards growth. Vitamin D is naturally formed by the action of direct sunlight on the bird and breeding birds do better when the aviary is flooded with natural light. Egg binding and soft shell eggs are rarely encountered in sunlit aviaries. Bent keels, splayed legs and beaks abnormality are the most common signs of a vitamin D3 deficiency. It is almost impossible to reverse these abnormalities.
natural health and vitality and functions as a biological anti-oxidant that may be important during the stress of overcrowding and during breeding when the formation of free radicals is increased. Vitamin E also has a positive effect on the immune function and any improvement in immune function must potentially benefit the breeding budgerigar and stressed young bird in the overcrowded aviary. Vitamin E deficiency may occur when rancid oils are fed excessively to the breeding pairs. All oil preparations must be refrigerated and tightly sealed. The signs of deficiency in budgerigars include twisting of the neck, stiff legs and leg weakness.
The B vitamins are energy vitamins used against stress and are all involved in the energy metabolism as cofactors in enzymatic reactions. They are extremely beneficial when the energy expenditure increase nine fold during the heavy feeding of the chicks. They aid in the continuing vitality of the feeding parents and maximise the growth of the chicks. Thiamine (vitamin B12) is an extremely important vitamin. Although seeds are a rich source of Thiamine, it is destroyed in budgerigars with enteritis. Thiamine supplements are given to accelerate the recovery of budgerigars during an enteritis outbreak. A cultured yeast by-product is an excellent source of Thiamine and B vitamins and is recommended for all breeding budgerigars on a daily basis.
Eucalypts have a special place in the life of the budgerigar. The wild budgerigar has evolved alongside the Eucalypt tree and over a million years has developed an intimate bond with the tree and its leaves. Wet eucalypt leaves excite and invigorate both the wild and aviary budgerigar into a frenzy of joy. They love to bath in the wet leaves and breeding hens destructively chew the bark searching for trace elements and lysine, the breeding protein. The eucalyptus oil from the leaves has medicinal properties that stimulate the immune system and promote a strong natural resistance to disease.
