Colour-ringed Herring Gull Update
I have just heard back about the colour-ringed Herring Gull from last week . It is obviously a site faithful bird, as it was ringed at Gerrard's Cross landfill (I assume the Hedgerley landfill site). It was ringed on 21st January 2004 as an adult, which makes it at least 12 or 13 years old - the ring was confirmed as 1652 on an orange darvic ring. It has not been reported since its ringing until now.
