Great tits: birds with character
Date:2/9/2010

In 2007, researchers of the Max Planck Institute for Ornithology found a gene related to individual variation in exploratory behaviour in great tits. Birds with a certain variant of this so-called "dopamine receptor D4 gene" (DRD4 gene) showed stronger novelty seeking and exploration behaviour than individuals with other variants. This association was originally tested and found in a lab-raised group of birds.

Now, a large international group of researchers around Bart Kempenaers, director at the Max Planck Institute for Ornithology, Germany, repeated the test in adult wild birds captured in the field. Research groups from the Centre for Terrestrial Ecology in Heteren (NL), the Universities of Antwerp (Belgium) and Groningen (NL), and the Edward Grey Institute of Field Ornithology in Oxford (UK) all measured exploratory behaviour of large numbers of great tits in a similar way. And they brought their data together to test the generality of the association between the different gene variants and exploration behaviour. "To our knowledge, this is the most extensive study of gene variants underlying personality-related behavioural variation in a free-living animal to date, and the first to compare different wild populations", says Peter Korsten, first author and a former member of Kempenaers' department.

Similar results in great tits and humans

To their surprise, the researchers found the association between the gene and the behaviour present in one population, but not in three others. "It was important to confirm the association between the DRD4 variants and exploratory behaviour in the original population", says Kempenaers, but he adds "We do not yet understand the differences between populations". However, the results mirror the outcome of similar research into gene-personality associations in humans, which also varies between populations. More than 30 studies confirmed that the DRD4 gene is associated with novelty seeking in humans,
