Whimbrels are an iconic species found worldwide, with several subspecies/populations facing dire situations but others apparently doing well. Studies of single populations have allowed us to understand the distribution, migration routes and behaviour of whimbrels, but by examining the global picture across subspecies and populations in a comparative framework we hope to gain deeper insights and uncover new routes for research.

Through a collaborative effort, we aim to create a global overview of whimbrel migration by:

1. Mapping all tracking data and overlaying it on current distribution maps to identify knowledge gaps, e.g. areas where no or very few individuals have been tracked.

2. Comparing migration metrics, associated morphometrics and trends between subspecies/populations, assessing underlying variation and fine tune relevant questions based on the patterns detected.

3. Calculating intra-individual consistency in time and space across the annual cycle, towards suggesting which groups may be more or less constrained in phenological responses.
