The group of Evolutionary and Behavioural Ecology of the Museum has been working since the early 1980s on aspects of social organisation, ecology, and population dynamics.
The group works in close collaboration with the following groups: Department of Zoology, Uppsala University (Suècia), Wildlife Unit de la University of Georgia (EUA) and Estación Biológica de Doñana – CSIC, with which the group shares coordination of several research projects.
The various lines of research are presented independently, although they are related to each other and share common objectives. An example of this is the study of the management of fat reserves, in which, using plumage coloration as a sign of social status, the degree of dominance of each individual can be predicted and the survival rates of dominant and subordinate birds can also be analyzed.
