By undertaking permitted ringing and tagging of birds we are seeking to gather information and data about the wintering waders on the Humber Estuary that take the body of relevant knowledge beyond estimates of bird numbers and more specifically to investigate:
A. The interrelationship between the overwintering and passage populations of waders on the Humber and the rest of the East Atlantic Flyway.
B. The importance of specific sites, including realignment sites, along the Humber for feeding and roosting waders and under what conditions.
C. The movements of birds between sites on the Humber and the turnover of individual species across the Humber.
D. Seasonality of movements within the Humber.
E. The influence of the tidal cycle on wader movement.
F. The influence of the day-night cycle on wader activity and behaviour.
This information is of particular conservation importance in relating wader distribution to site development pressure.
Ringing of waders by HWRG will continue to provide more general information on wader survival rates (as part of the BTO Integrated Population Monitoring Programme), biometrics, ageing and moult.
