Signal redundancy as a strategy for increasing the chance of information transmission in noisy habitats

Project duration: 2013-2016

Head of the project: Krzysztof Deoniziak

Supervisor: Tomasz Osiejuk

The main aim of the research is to experimentally determine, whether signal redundancy can be an useful strategy for increasing the chance of transmission of the information contained in bird song under in habitats polluted by anthropogenic noise. In order to do so, we will verify if: (1) signal redundancy increases the active space of transmitted information in habitats polluted with anthropogenic noise; (2) bird song containing excess amount of syllable types cause significantly different reaction in territorial males than songs containing usual amount of them; (3) bird song containing excess amount of song types in bouts cause significantly different reaction in territorial males than songs containing usual amount of them.
