Birds sacrifice food for love
Wild birds readily sacrifice access to food in order to stay close to their partner over the winter, a study says.
London: Wild birds readily sacrifice access to food in order to stay close to their partner over the winter, a study says.
Scientists found that mated pairs of great tits chose to prioritise their relationships over nutrition in a novel experiment that prevented couples from foraging in the same location.
The results demonstrate the importance of social relationships for wild birds - even when pursuing those relationships appear to be detrimental.
The research involved the use of automated feeding stations with the ability to decide which individual birds could and could not access the food inside. Birds were allowed access based on radio frequency identification tags that were linked to the feeding stations.
In the experiment, mated pairs of birds were unable to access the same feeding stations as each other, meaning the male could only access the feeding stations that the female could not, and vice versa.
The researchers found that the birds randomly selected not to be allowed access to the same feeding stations as their partner spent significantly more time at feeders they could not access than birds that were allowed to feed together.
