breeding behaviour, bird watching, reproductive success
The project overview
In birds, reproductive success can be related to individual fitness but also provides a better understanding of their adaptive capacity. However, bird species behave differently at the nest and apply different breeding strategies. Greylag geese, for example, are precocial, long-term monogamous and the female takes care of the nest alone. The endangered northern bald ibis, on the other hand, is altricial, seasonally monogamous and both partners take care of the nest.
The aim of the project was to investigate the breeding behaviour of the two avian species with different breeding strategies in order to clarify why there are successful and unsuccessful pairs within a flock or colony of birds. Therefore, citizen scientists watched and coded videos showing the breeding behaviour of greylag geese and northern bald ibises.
How did citizen scientists participate?
Citizen scientists watched and coded short video sequences taken at the nests of breeding northern bald ibises and greylag geese.
In order to verify the codings, each video was shown to numerous citizen scientists. Only after a video has been coded the same way by different users, the coding was marked as true.
What happened to the contributions of citizen scientists?
The coded video sequences provided the dataset for statistical analysis in order to relate observed behavioural patterns to the reproductive success of single individuals. The results will be presented as contributions to conferences and peer-reviewed journals.
How are winners being determined
The winners will be determined by the number of coded videos, the more the better. The accuracy of the observation is automatically checked by the system.
The winners will be announced at the festive ceremony on 19 November 2019.
