And then there was one

It looks like the two eldest chicks in the quad are definitely gone for good (well, at least until next season - they seem to come back to breed each year). Meanwhile, the Runner is still biding his/her time in the quad, and is currently in the large water trough. Hatched around a month later than the eldest chicks, the Runner should be ready to leave the quad before the end of September. Perhaps we'll be leaving NOCS at the same time?
