Black-billed gull- a local movement


Hi all this bird was sighted next to the Avon River in central Christchurch in March 2010 and was banded almost twelve years prior on the Ashley River- about 30km north. Note birds bill and leg colour- which is highly variable for gulls.
Increasing more information is coming to hand about black-billed gull longevity. Twevle years may not be particularly old for this species.
