House Sparrow TS82001
Unfortunately I have yet to submit my application to set up a RAS (Retrapping Adults for Survival), project for the House Sparrows that visit my garden which would include colour ringing to remove the need for retrapping; so I hope to catch TS82001 at least one more time.
For more information about RAS which aims to study the survival of adults in bird populations please visit the BTO RAS page.
