Mate choice in a monomorphic dull bird social species: a role for behavior ?
The objective of my thesis is to understand the mate choice in a monomorphic dull bird social species (Sociable weavers, Philetairus socius), with no extra pair copulation and no divorce. This research is supervised by Claire Doutrelant and Rita Covas (CIBIO, Porto, Portugal). The PhD is focusing on the potential role for sexual selection on the nest building behavior as well as the plumage. I analyse a large long term data rpoject dataset and also do a lot of field observations of the bird's behavior. My objectives are:
- To estimate Bateman's gradient and the opportunity of the sexual selection among the indviduals of the different studied populations.
- To analyse the force of the sexual selection for potential secondary sexual traits (the bib and the scaly feathers).
- To evaluate the role for the sexual selection on the nest building behavior. The aim is to understand who built, where and when and to also evaluate the cost of this behavior as well as the effect of competition and audience on the bird's behavior.
The ecological problematics are not my only interest, as I a part of my research focuses on artificial intelligence (Deep learning) methods en ecology science. During my PhD, I will implement several neural networks in order to, first automate the data extraction on pictures of phenotypic traits (bib and scaly feathers) and second partly analyses the nest building behavior.
