The Italian Kestrel group (Ornis italica)

Our group deals primarily with evolutionary physiology of birds using the Eurasian kestrel (Falco tinnunculus) as a model species. Specifically, we are interested in the proximate and ultimate factors that affect the physiology of carotenoids and oxidative stress and the role that carotenoid-based colours play in the mate choice.

In addition, other research topics investigated by our group are:
(i) monitoring nest-boxes (n=±250) of kestrels since 1998 in order to collect data about their reproductive biology,
(ii) collecting blood samples for DNA analysis for population genetics,
(iii) keeping samples for eventually investigating (when funds will be available) genotoxic effects of exposure to magnetic fields (nest boxes are on electric pylons), and finally
(iv) collecting ecototoxicology data for assessing the exposure of our kestrel to PCBs and other environmental contaminants.

For the last three years during the breeding season, we have been runing a project with three societies of ENEL, the main Italian power company, called the "nests on-line" project for observing the life of kestrels and peregrines on their nests using internet birdcams (www.enelbirdcam.com, www.birdcam.it). We also collaborate with another local power company called ACEA.

We are all volunteer scientists and recently we organised in a small non-profit research association, Ornis italica (www.ornisitalica.com) for interfacing with institutions and other research groups.

We are open to scientific collaborations with other institutions and researchers working on raptors and other birds of prey all around the world.
