Article Synopsis
- Researchers studied how a bird called the thick-billed murre finds food in different environments, focusing on two colonies in the Arctic that are different sizes.
- They used GPS trackers to measure how far the birds traveled and how much energy they used while foraging.
- The larger colony’s birds had a harder time finding food compared to those at the smaller colony, especially during certain ice conditions, showing that their success depends on the environment and their colony size.
Many ecosystems have experienced anthropogenically induced changes in biodiversity, yet predicting these patterns has been difficult. Recently, individual behavioural and physiological measures have been proposed as more rapid links between environmental variation and fitness compared to demographics. Glucocorticoid hormones have received much attention given that they mediate energetic demands, metabolism, and foraging behaviour.
