Temperature and photoperiod as environmental cues affect body mass and thermoregulation in Chinese bulbuls, Pycnonotus sinensis.
Seasonal changes in temperature and photoperiod are important environmental cues used by small birds to adjust their body mass (Mb) and thermogenesis. However, the relative importance of these cues with respect to seasonal adjustments in Mb and thermogenesis is difficult to distinguish. In particular, the effects of temperature and photoperiod on energy metabolism and thermoregulation are not w...
متن کاملThe Nest Defense Behavior of Eastern Screech-Owls: Effects of Nest Stage, Sex, Nest Type and Predator Location
The responses of male and female Eastern Screech-Owls (Otus asio) to a human approaching the nest were examined. Intensity of nest defense as measured by distance of approach, number of flights and dives, and number of vocalizations was more pronounced during the nestling stage than during the incubation stage. These results generally support both the age-investment and positive-reinforcement h...
متن کاملDietary protein influences the rate of 15N incorporation in blood cells and plasma of Yellow-vented bulbuls (Pycnonotus xanthopygos).
The rate at which an animal's tissues incorporate the isotopic composition of food determines the time window during which ecologists can discern diet changes. We investigated the effect of protein content in the diet on the incorporation rate of (15)N into the plasma proteins and blood cells of Yellow-vented bulbuls (Pycnonotus xanthopygos). Using model comparison analyses, we found that one-c...
