Giardia Infection in Budgerigars (Melopsittacus undulatus)
The Japanese Journal of Veterinary Science, 1980 セキセイインコ4～6,000羽を飼育する愛知県の某愛玩鳥業者において, 羽毛の逆立, 飲思・食欲の減退, 削痩および下痢の症状を呈し死亡する疾病の発生が観察された. 斃死あるいは殺処理されたセキセイインコの腸内容の新鮮生標本から, ジアルディア原虫が25～58%の率で検出された. 下痢を主徴とするこの疾病の主原因はジアルディア原虫と考えられた. 原虫の治療には飲水からのジメトリダゾールが効果的であった.

Visual acuity of budgerigars for moving targets
Biology Open, 2021 For a bird, it is often vital to visually detect food items, predators, or individuals from the same flock, i.e. moving stimuli of various shapes. Yet, behavioural tests of visual spatial acuity traditionally use stationary gratings as stimuli.

Cognition, personality, and stress in budgerigars, Melopsittacus undulatus [PDF]
Behavioral Ecology, 2017 To study the fitness effects of individual variation in cognitive traits, it is paramount to understand whether traits such as personality and physiological stress influence cognitive performance. We first tested whether budgerigars showed both consistent personalities and cognitive performance across time and tasks. We tested object and food neophobia,

Morphology of the basilar papilla of the budgerigar, Melopsittacus undulatus [PDF]
Journal of Morphology, 1993 AbstractThe budgerigar is a representative of the parrot‐like birds that, like song birds, have developed complex communication signals. This species is interesting in a psychoacoustic sense, in that it shows unusually good frequency discriminative abilities above about 1 kHz.

Behavioural lateralization in Budgerigars varies with the task and the individual. [PDF]
PLoS ONE, 2013 Handedness/footedness and side biases are a well-known phenomenon in many animals, including humans. However, these so-called biases have mostly been studied at the population level--individual biases have received less attention, especially with regard ...

Experience with speech sounds is not necessary for cue trading by budgerigars (Melopsittacus undulatus). [PDF]
PLoS ONE, 2017 The influence of experience with human speech sounds on speech perception in budgerigars, vocal mimics whose speech exposure can be tightly controlled in a laboratory setting, was measured.
