Ive spent a little time over the years bird-watching
at Bird Observatories, places like Spurn Point in East Yorkshire, Portland Bill in Dorset, Holme in Norfolk. They are always great and attract a good variety of birds. They are however best during the migration season and that is their main purpose.
at these hotspots provides us with important information about the movements of our birds and can help us to understand why, when and where our birds move to.
move in many ways, not only to migrate from country to country in breeding seasons but also move in harsh weather conditions within their own country. Many birds may move to the coast during cold snaps as temperatures are nearly always a few degrees warmer at those locations, birds move during food shortages, in search of better feeding opportunities.
The numerous bird
observatories spread out around the country and indeed the world, trap birds in Mist Nets, they measure, weigh, sex and age the birds, they put a small metal ring on the leg which has an individual number on it, so, if trapped again at a different location, information can be found about its movements and timeframes.
Its amazing the information that has been gained through this technique. Who’d have thought that a bird like a common ‘resident’ Starling
would be found in a garden in Lancashire with a ring on its leg that shows it was rung as a youngster 1559 kilometers away in Lithuania, Amazing! We found out that Swallows
migrated to Africa in the same way!
Ringing is often thought of as being cruel but no harm is done to the bird and the valuable information about movement, migration, distribution, age and longevity is incredibly useful in understanding our native birds
habits and movements.
