Nestling activity levels during begging behaviour predicts activity level and body mass in adulthood
Across a range of species including humans, personality traits, or differences in behaviour between individuals that are consistent over time, have been demonstrated. However, few studies have measured whether these consistent differences are evident in very young animals, and whether they persist over an individual's entire lifespan. Here we investigated the begging behaviour of very young cro...
متن کاملThe energetic cost of begging behaviour in nestling house wrens.
This study presents data relevant to the hypothesis that the energy expenditure associated with begging influences the signalling of need by nestling birds. We used open-circuit respirometry to measure the energy costs of resting, begging and non-begging activities in nestling house wrens, Troglodytes aedon, ranging in age from 1 to 11 days post-hatching. Across all ages, begging caused a 27% i...
متن کاملOxidative stress, activity behaviour and body mass in captive parrots
Many parrot species are kept in captivity for conservation, but often show poor reproduction, health and survival. These traits are known to be influenced by oxidative stress, the imbalance between the production of reactive oxygen species (ROS) and ability of antioxidant defences to ameliorate ROS damage. In humans, oxidative stress is linked with obesity, lack of exercise and poor nutrition, ...
