Resumo
Noise pollution exerts negative well-being effects on animals, especially for captive individuals. A decrease in
feeding, reproduction, attention, and an increase in stress are examples of negative effects of noise pollution on
animals. Noise pollution can also negatively impact animals’ lives by decreasing the efficiency of food choice:
attention decrease can cause animals choose the least profitable food, which can affect their fitness. The aims of
this study were to analyse the effects of noise on feeding behaviour and food preference of saffron finches.
Foraging tests were performed under background sound pressure levels and under a noisy condition. The behaviours exhibited by the birds during the tests were recorded using focal sampling with instantaneous recording
of behaviour every 10 s. Results showed that finches consumed more the higher energetic food, and that noise
pollution did not impact food consumption by the birds. Noise changed the number of visits on the feeders, and
increased the expression of the ‘lower the head’ and vigilance behaviours during feeding. These findings could be
important for wild and captive animals because an increase in vigilance and in changes in foraging behaviour
could ultimately impact their fitness. Thus, mitigation measures should be taken in relation to noise impact on
wildlife, this is especially the case for captive animals, which have no chance to avoid noisy environments.
