  1. Development of Auditory Sensitivity in Barn Owls (Tyto furcata pratincola)

    … other developing vertebrates, including kittens, budgerigars, chickens, and gerbils. The onset of hearing began sometime earlier than the second week post-hatch, and proceeded in a frequency-dependent manner. Adult-like thresholds were reached in a progression from low to high frequency, and …

  2. Roles of dietary antioxidants and oxidative stress in mediating fitness related traits in birds

    … stress produced during exercise in adult captive budgerigars Melopsittacus undulatus. Supplementing blue tit parents with [alpha]-tocopherol, a potent dietary antioxidant, before and during egg laying did not affect maternal condition, nor reproductive performance. Mothers supplemented with …

  3. Behavioral Ecology and Associated Virology of Mosquito-Host Interactions in Southern California

    … study examined the anti-mosquito behaviors of budgerigars (Melopsittacus undulatus) in a laboratory study. The birds defended themselves by increased frequencies of at least five maintenance behaviors, especially foot shake. These behaviors increased over a 2-hour period of exposure, and varied …

  4. Adventitious differential reinforcement of emergent sample-specific behavior and common coding in pigeons' matching-to-sample

    … Manabe, Kawashima, and Staddon (1995) trained budgerigars on a matching-to-sample task with two samples mapped onto each com parison stimulus (many-to-one training), where sample-specific vocal responses were required for one set of samples. Sample-specific responding emerged for the other set …

  5. Development and characterization of DNA markers for two avian species

    Central to the application of genomics to animal agriculture are DNA markers, especially microsatellites and single nucleotide polymorphisms. These markers are the resources necessary for constructing genetic maps and for determining how improved and unimproved animal breeds are related. Here, DNA …
