One good Tern deserves another.

Following up Russel's 2 Little Terns, over the last hour the flock has got bigger and bigger. Four superb Black Terns are at the mouth of the Leri (one summer plumaged and 3 winter birds), there are now 4 Little Tern ( 3 adult and a juv), one adult Arctic, seven Common and 250+ Sandwich Tern. A Greenshank too.
