UAV’s or drones are increasingly being used in environmental science, as a great way of gathering imagery and deploying sensors. In mid September, Richard Lucas, from UNSW organised a fantastic meeting, which brought together a range of different UAV’s and sensors for a few days of frenetic data gathering. We were lucky enough to get involved, and helped to set up ‘challenges’ and ground truth some of the data acquired. The data that has now been gathered in Lake Paddock (the central area for the chestnut-crowned babbler project), and Gap Hill (the key area for our work on zebra finches), will provide excellent insight into the link between landscape, vegetation and avian ecology, once it is all processed and analysed.
One of the papers from Enrico Sorato’s PhD work was published today in the Journal of Animal Ecology. In the paper, we showed that in the chestnut-crowned babbler,
individuals suffer a cost of hanging around with their group mates, even if they are not actively involved in feeding offspring. That’s because over the course of a breeding attempt the foragers have to move further into the territory away from the nest to find enough food, incurring greater costs of moving and foraging. This cost, which has not been considered before may help to understand individual decisions about when to stay and when to leave a social group, and will contribute to the optimal group size. The paper is entitled The price of associating with breeders in the cooperatively breeding chestnut-crowned babbler: foraging constraints, survival and sociality, and can be found here.
Fowlers Gap Arid Zone Research Station, where we conduct a lot of our ongoing fieldwork, has received 32mm of rain in a rain event over 7-8th May. This is a significant amount and will help to replenish the environment out there and set up a good winter and hopefully good breeding conditions for the zebra finches and chestnut-crowned babblers………
