  • Hearing in the Starling (Sturn Us Vulgaris): Absolute Thresholds and Critical Ratios
    Bulletin of the Psychonomic Society 1986, 24 (6), 462-464 Hearing in the starling (Sturn us vulgaris): Absolute thresholds and critical ratios ROBERT J. DOOLING, KAZUO OKANOYA, and JANE DOWNING University of Maryland, College Park, Maryland and STEWART HULSE Johns Hopkins University, Baltimore, Maryland Operant conditioning and a psychophysical tracking procedure were used to measure auditory thresholds for pure tones in quiet and in noise for a European starling. The audibility curve for the starling is similar to the auditory sensitivity reported earlier for this species using a heart­ rate conditioning procedure. Masked auditory thresholds for the starling were measured at a number of test frequencies throughout the bird's hearing range. Critical ratios (signal-to-noise ratio at masked threshold) were calculated from these pure tone thresholds. Critical ratios in­ crease throughout the starling's hearing range at a rate of about 3 dB per octave. This pattern is similar to that observed for most other vertebrates. These results suggest that the starling shares a common mechanism of spectral analysis with many other vertebrates, including the human. Bird vocalizations are some of the most complex acous­ METHOD tic signals known to man. Partly for this reason, the Eu­ ropean starling is becoming a favorite subject for both SUbject The bird used in this experiment was a male starling obtained from behavioral and physiological investigations of the audi­ the laboratory of Stewart Hulse of 10hns Hopkins University.

  • Parakeet (Budgerigar)
    PARAKEET (BUDGERIGAR) The budgerigar (Melopsittacus undulatus) also known as common pet parakeet or shell parakeet and informally nicknamed the budgie, is a small, long-tailed, seed-eating parrot. Budgerigars are the only species in the Australian genus Melopsittacus, and are found wild throughout the drier parts of Australia where the species has survived harsh inland conditions for the last five million years. Budgerigars are naturally green and yellow with black, scalloped markings on the nape, back, and wings, but have been bred in captivity with colouring in blues, whites, yellows, greys, and even with small crests. Budgerigars are popular pets around the world due to their small size, low cost, and ability to mimic human speech. The species was first recorded in 1805, and today is the third most popular pet in the world, after the domesticated dog and cat. They are very active, playful birds, and they are incredibly intelligent. Some (but not all) budgies learn to talk, there are even budgies have a 100+ word vocabulary! Budgies can easily become finger tame while they are young with some diligent training, even if they were not hand fed as babies. Many owners of fully tamed budgies will swear that their budgie thinks it's a human! Even if a budgie is not tamed, they still make enjoyable pets. Their antics and singing will brighten up any room in your home. And budgies who are not finger tame still can become friendly towards you, and even still learn to talk. Name Many people know them as "parakeets," but their real name is "budgerigar".

  • Rainbow Budgies Are a Combination of Several Mutations in the Blue Range and Therefore Not an Independent Mutation
    Rainbow budgies are a combination of several mutations in the blue range and therefore not an independent mutation. The name “rainbow” was first used by Keston Foreign Bird Farm who create this wonderful and colourful budgerigar. The Boosey brothers owners of the Keston Foreign Bird Farm create this bird for petshops in England. Previously such bird have been bred in England and on the Continent, usually by change. No respected breeder at that time was interested in these birds. At the Keston farm they only used yellow-faced and goldenfaced opaline whitewing blue an cobalt. As yellow-face they practiced the Mutant 2 and as golden face they used what we know as Australian yellowface. Today we see also visual violets and mauves. What we have to avoid are the grey birds. On the shows they accept also the yellowface Mutant 1 but in my opinion is it better not to use this mutation. The colour of the rainbow is more attrac- tive when we practice the Yellow face Mutant 2 and Australian yellowface birds. The last ones known as the Goldenface rainbow. The problem with breeding rainbow’s is the size of the bird. My experience tells me that finding good whitewings is very difficult because the white- wings on the continent are different from the whitewings in Australia and that are the birds we needed to breed the real rainbow. For that reason the Keston Farm imported Australian whitewings and Australian yellowfaces. YELLOWFACE GROUP YELLOWFACE (MUTANT 1) All varieties in the blue series The standard will be as for all the different varieties in the blue series including grey and should conform in every respect except in the follo- wing details: General body co- as the corresponding white face variety.

They daz- zle the beholder with every color in the rainbow (figure 3). They range in size from tiny pygmy parrots weighing just over 10 grams to giant macaws weighing over a kilogram. They consume a wide variety of foods, including fruit, seeds, nectar, insects, and in a few cases, flesh. They produce large repertoires of sounds, ranging from grating squawks to cheery whistles to, more rarely, long melodious songs. They inhabit a broad array of habitats, from lowland tropical rainforest to high-altitude tundra to desert scrubland to urban jungle. They range over every continent but Antarctica, and inhabit some of the most far-flung islands on the planet. They include some of the most endangered species on Earth and some of the most rapidly expanding and aggressive invaders of human-altered landscapes. Increasingly, research into the lives of wild parrots is revealing that they exhibit a corresponding variety of mating systems, communication signals, social organizations, mental capacities, and life spans.
