So it’d be more about habitat destruction &/ climate shifts across the entire ranges of the cuckoo spp., & the effects of these upon population numbers, forage, & breeding, of all the cuckoos & all their hosts. For example, what if there are less small or bush birds here? Or what about abrupt habitat changes north of us. Or climate extremes on migration. Or decoupling of forage/prey life cycles with those of the birds’?
To our superficial gaze the affects & effects of interactions or agonistics might be misunderstandings in passing.
