Not strictly escapes but the pair of black swans at the Wellhead, Bourne (released earlier this year -see below) now have 4 cygnets (seen by me 23rd November); a third adult black swan is still present on St Peter's Pool. Enough to make the local news:

Note this pair of swans were released this year when the previous 3 birds were reduced to a single swan
