I strayed across the estuary this morning and was rewarded by a few brief sightings of one or more bearded reedlings. Also one green sandpiper and a large flock of curlew, black-tailed godwits, black-headed gulls and a few whimbrel. There was one leucistic black-headed gull - its build and shape identical to a bhg, all white plumage with the faint outline of a black hood (does this suggest an adult?). The bill was fine and very orange. I failed to see its legs as it was swimming.
On the estuary 16 shelduck included some juveniles.
