That Bird Blog – Bird Care and History for Pet Birds

Note: Please see Natural History of the Budgerigar for information on budgerigars in the wild.

Introduction
From its introduction to European aviculture by eminent British ornithologist John Gould in 1840, the budgerigar has grown to be the world’s most commonly kept pet bird.  Perhaps due to their tiny size, budgerigars are often underestimated as pets.  However, they are as playful and intelligent as any of the larger parrots, and often develop impressive vocabularies. 

The budgerigar’s sociability and calm acceptance of crowded, noisy surroundings renders it an ideal pet for people who do not have the space that larger birds require – believe me, you will not be missing anything offered by parrot ownership if you choose to keep this delightful little fellow.

Enclosure and Physical Environment
As with all birds, you should give your budgerigar the largest cage possible – just be certain that the bars are no more than ½ inch apart, lest the bird escape, or get caught up in the attempt.  Assuming that your pet is given frequent exercise periods outside of its cage, the minimum cage size for a single bird would be 12”x18”x18”.

Budgerigars are extremely active, even by parrot standards.  Fortunately, they adjust well to people and most soon tame down enough to be let out of their cage for daily exercise.

The cage should be furnished with a variety of perches of different sizes and materials and a wide selection of toys.  Rotating toys in and out of the cage from time to time will increase your bird’s interest in them.  Even more than many of their relatives, budgerigars enjoy gnawing away at all sorts of materials, so be sure to keep them well supplied with suitable chew toys.

In the warmer months, budgerigars housed in an outdoor aviary will keep you amused for hours on end with their antics.

Light and Heat
Budgerigars are birds of open, sunlit environments, and will benefit greatly from exposure to unfiltered sunlight.  If possible to do so safely, occasionally place your pet’s cage (locked and out of reach of predators) outdoors in nice weather.  Be sure the bird can get into the shade when necessary.

When indoors, your budgerigar’s cage should be lit with a full spectrum bird bulb – UVA light in particular has been shown to be of great benefit in stimulating natural behaviors and maintaining good health.

Normal room temperatures suit these hardy birds just fine, but do not position the cage in a draft.

Overview
The budgerigar (or “budgie”), more commonly referred to as “parakeet” in the USA, is undoubtedly the most commonly kept parrot, if not bird, in the world.  In fact, many think of the budgerigar as a purely domesticated species, and know little of its existence in the wild.  Yet it is Australia’s most numerous parrot, and arguably the most abundant bird on the continent.  Today we will take a look at how it lives in the wild, followed by notes on captive care next time.

Classification
Budgerigars are true parrots, and are classified along with all others in the order Psittaciformes.  They are the only members of their genus.

Physical Description
With so many captive bred color varieties available, it is easy to forget that the natural coloration of these 7 inch long parrots is quite beautiful.  The upper body is barred in yellow and black, and the rump and under-parts are bright green.  The forehead and face are a brilliant yellow.  Feathers tipped in blue-violet decorate the cheeks and black spots mark the yellow throat.

The cere (the area above the beak, where-in the nostrils are located) is blue in males, pink in non-breeding females and brownish in breeding females.

Wild budgerigars are usually significantly smaller than individuals from captive-bred strains.

Range
The huge range encompasses nearly all of Australia with the exception of coastal regions and the Cape York Peninsula in the northeast (they sometimes appear in these areas during droughts).  Budgerigars are absent from nearby Tasmania and New Guinea.

Budgerigars have been reported as free-ranging in the USA, Japan, South Africa, Puerto Rico, Switzerland and New Zealand.  Surprisingly, however, the only introduced breeding population seems to be in Florida.

Many years ago I observed an escaped pet budgerigar take up with a flock of house sparrows in NYC.  The budgerigar foraged and roosted with the sparrows and was never seen singly, but perished during the winter.

Habitat
Budgerigars favor sparsely wooded habitats along watercourses, dry scrub and grasslands, and sometimes enter agricultural areas as well.  They occur in arid and semi-arid regions, but need to drink daily and so are to be found within flying distance of water.  Droughts drive huge flocks to the coasts, and cause massive die-offs.

Oddly at first glance, budgerigars often move into desert habitats during Australia’s frequent droughts.  However, desert-adapted plants such as the various tussocks, bandicoot grass, salt bush and blue bush may support seeds even during the driest of years, and hence help to see the birds through such periods.  However, the lack of water and low soil calcium levels (and hence low-calcium seeds) make the habitat far from ideal, and reproduction comes to a halt.

It has long been known that male budgerigars imitate the calls of their mates, and that doing so seems to strengthen the bond between the pair. Budgerigars have highly variable contact calls, more so than many other parrots. This may help the pair to maintain contact and to thwart competition within the huge flocks that parakeets typically form. The current research is the first to show that female mate choice is influenced by the initial sound of the male’s contact call, before he has begun to imitate her sounds.

Although budgerigars breed readily for pet keepers, this information may have important implications for hobbyists and zoos working with rare parrots that do not reproduce reliably in captivity.
