Traffic noise causes song learning deficits in birds: Study

Traffic noise causes song learning deficits in birds: Study

Updated: May 15, 2021 22:58 IST
Berlin [Germany], May 15 (ANI): A new study by researchers of the Max Planck Institute for Ornithology and colleagues shows that young zebra finches, just like children, are particularly vulnerable to the effects of noise because of its potential to interfere with learning at a critical developmental stage.
Traffic noise is a pervasive pollutant that adversely affects the health and well-being of millions of people. In addition to severe noise-induced diseases in adults, traffic noise has also been linked to learning impairments and language deficits in children.
In order to analyse the causal mechanisms connecting chronic noise exposure to cognitive deficiencies, researchers of the Max Planck Institute for Ornithology with colleagues at the University of Paris Nanterre and the Manchester Metropolitan University studied song le ....

Natural History Museum project highlights the impact of COVID-19 – UKRI

Natural History Museum project highlights the impact of COVID-19
22 September 2020
A Natural Environment Research Council (NERC) COVID-19 public engagement funded project has produced infographics to show changes in the movement of people, air and noise pollution, and wildlife sightings in the UK during lockdown.
The Natural History Museum has collaborated with data visualisation company Beyond Words to illustrate some of the environmental changes wrought by lockdown.
The graphics, drawing on a variety of open source data and scientific databases, including data from NERC-supported centres – UK Centre for Ecology & Hydrology (UKCEH) and the British Geological Survey, document the dramatic drop in driving and public transport use, the resulting reduction in air pollution and noise levels and the changes to sightings of both animals and birds. ....

Global study on bird song frequency

An analysis of the songs of most of the world s passerine birds reveals that the frequency at which birds sing mostly depends on body size, but is also influenced by sexual selection. The new study from researchers of the Max Planck Institute for Ornithology and colleagues suggests that habitat characteristics do not affect song frequency, thereby refuting a long-standing theory.
Many animals use acoustic signals for communication. These signals have evolved to maximize the effectiveness of the transmission and reception of the sounds, because this helps finding a mate or avoiding predation. One of the fundamental characteristics of acoustic signals is the frequency of the sound. In forested habitats, acoustic signals become attenuated because of sound absorption and scattering from foliage, ....
