I just started reading the book "H is for Hawk". The first page has a review that says:
This beautiful book is at once heartfelt and clever in the way it mixes elegy with celebration: elegy of a father lost, celebration of a hawk found- and in the finding also a celebration of countryside, forbears of one kind and another, life-in-death. At a time of very distinguished writing about the relationship between human kind and the environment, it is immediately pre-eminent. – Andrew Motion

Forbear means probably ancestors here. What is the implied meaning, I can't understand.
