Evolutionary conservation of Kv3.1 in the barn owl Tyto alba.
For prey capture in the dark, the barn owl Tyto alba has evolved into an auditory specialist with an exquisite capability of sound localization. Adaptations include asymmetrical ears, enlarged auditory processing centers, the utilization of minute interaural time differences, and phase locking along the entire hearing range up to 10 kHz. Adaptations on the molecular level have not yet been inve...
متن کاملBarn owl (Tyto alba) siblings vocally negotiate resources.
Current theory proposes that nestlings beg to signal hunger level to parents honestly, or that siblings compete by escalating begging to attract the attention of parents. Although begging is assumed to be directed at parents, barn owl (Tyto alba) nestlings vocalize in the presence but also in the absence of the parents. Applying the theory of asymmetrical contests we experimentally tested three...
متن کاملThe influence of hatching order on the thermo- regulatory behaviour of barn owl Tyto alba nestlings
Adult birds maintain high body temperature in cold environments by the insulating properties of their plumage, particular behaviours such as huddling and communal roosting (Ancel et al. 1997), and a high capacity for thermogenesis. In nestlings, the capacity for thermoregulation is limited by constraints specific to young organisms. For example, compared to adults, chicks have a less favourable...
متن کاملGrowth and food requirement ̄exibility in captive chicks of the European barn owl (Tyto alba)
The growth and the food requirements of the European barn owl (Tyto alba) were studied in three groups of captive chicks. One group of chicks, raised in ad libitum food conditions by their parents, was used to measure body mass and linear growth of a number of structural body components at their characteristic growth rate. A second group of chicks, hand-raised with food ad libitum until ̄edging...
متن کاملEffects of environmental temperature on thyroid hormones in the barn owl (Tyto alba).
The basic patterns of thyroid hormones [thyroxine (T4) and 3,3',5-triiodothyronine (T3)] and the T4 and T3 responses induced by thyrotropin releasing hormone (TRH) are reported in captive female barn owls (Tyto alba) during the non-breeding period. The main findings of the study, conducted on a total of 10 owls, are as follow: (1) The thyroid gland of barn owl can be stimulated by the classical...
