Meanwhile, the peregrine's smaller cousin, the hobby, is still feeding its young, two months after the peregrines were busy feeding theirs. Why the time difference?
Well, hobbies are migrants wintering in southern Africa (where they mostly feed on insects such as termites) and returning to the UK in late April and May. They also use old crows nests, nearly always in trees. Their breeding season is timed so that the young are growing up just when there are plenty of young birds on the wing - in particular, the young of swallows, martins and swifts.
