Research interests

I am interested in Behavioural Ecology and animal communication in general, and in vocal signals in particular. My PhD focuses on the signalling system of chicks in the Barn Owl (Tyto alba), in a context of begging and sib-sib competition and negotiation (see Group Roulin). I will focus on:

  1.  the acoustic cues involved in the sib-sib negotiating vocal behaviour (individual and kin recognition, significance),
  2.  the evolutionary significance of these cues and behavioural interactions,
  3. and more broadly on the evolution of vocalisations and language.
