Izzy Fry gave us a fascinating talk on bird ringing last week at our final meeting of the year. The British Trust for Ornithology (BTO) regulates bird ringing in this country and Izzy has built up a huge amount of experience over the last 4-5 years in a range of locations and with different mentors, and even at night for the nightingales and nightjars, as she works towards a professional qualification.
As always Izzy's photographs were beautifully clear and expressive, and we were treated to a panoply of stunning close-ups of birds and saw how the fine meshed nets, which gently capture the birds, were stretched out near field boundaries. The birds go still in these nets and don't flap, so there is no harm to them in the process. Tall ladders (12 feet or more) can be set up for inspecting raptor nests and there are even ring sizes for baby birds which are delicately handled by those who have a special licence.
We heard how the ringing of birds has helped to further our knowledge about migratory journeys, when the codes from the leg rings of captured or dead birds are reported back to the BTO from overseas. The practice of doing regular bird-ringing in the UK also contributes to our understanding of the populations of species around the country, as it provides valuable longitudinal data sets for the BTO.
