Thames swan count: Dogs cause drop in numbers

The annual swan count on the River Thames has shown a drop in numbers.

The Queen's swan marker David Barber has said that figures are "looking on the low side" this year, blaming dog owners for allowing their pets to disturb nests in April and May.

The count is one of the oldest traditions on the river, dating back to the 12th Century, when swans and cygnets are counted and given a health check.

The count started on Monday in Sunbury, Surrey with boaters heading on to Berkshire on Wednesday and Thursday, ending in Abingdon, Oxfordshire on Friday.
