Dipper first juveniles on the wing

My first fledged Dipper of the year today on the River Wye north of Rowsley. Assuming around 17 days to incubate the egg and 22 days as a nestling and that this bird has recently fledged the egg would have been laid in the first week of March.
Dipper - juvenile
Average laying dates are late March so this is early, even by Dipper standards and probably reflects the mild winter and warm temperatures in March.
