Opposites may attract, but they don't make better parents
Date:1/27/2011

ls while they were feeding their chicks, and monitored the progress of hatchlings to see which couples were doing the best job as parents.

Dr Nick Royle, another author on the study, said: "We found that if birds were highly exploratory and their partners shared that trait, their offspring were in really good condition. It was the same for highly aggressive birds. If only one parent showed the trait, the chicks fared less well.

"Our study ruled out the idea that this was due to genetic compatibility, so this could only be due to the behavioural compatibility of the individuals while they were raising offspring."
