The Serin, a type of bird very common in urban areas in Europe manage to compensate the negative effects of noise of the city to devote more time to sing, according to a study published in the journal Behavioral Ecology.
"These birds can use up to 60% of the time to sing at levels of 70 decibels, but from that start singing at least, probably because more time for singing too much can interfere with such important tasks as to watch for predators or other greenfinches neighbors, "said Mario Diaz CSIC researcher.
birds can use up to 60% of the time to sing according to the study, the adjustment to the noise levels indicated that singing involves risks. "Even birds that have colonized noisy environments, such as greenfinches, may be conditioned by the increased risk associated to offset the effects of noise singing," says Diaz.
Moreover, researchers have observed that birds are rapidly changing their behavior depending on the noise level variation between weekdays and weekends.
Adapt to survive
The research examines the potential response of these animals to global changes resulting from human influence on the planet funcionamieto.
"Almost all the predictions are quite catastrophic, because they generally do not provide the flexibility of agencies to changes in their environment. The species can compensate for these changes by flexible behavior, but only to a point "says the researcher.
Learn how effective are the different responses of living organisms to increased levels of noise taxes by human activities will allow more reliable predictions about future changes in the distributions of organisms
