I'm very fond of them. They have been coming into the garden to gather nesting material lately. They will later bring the chicks along for a feed. The sound the chick makes when hungry is dreadful. I once dashed outside thinking something was dying or choking and found a baby hadeda shouting at its parents for grub.
They get annoyed with me if I happen to go out with the dog and don't see them foraging. The dog always gives them a good chase and they drift up onto the roof and sit there shouting at us in Hadeda language. Big round brown eyes peering down accusingly. They are a scream, really. And they eat snails and King Crickets so they are also welcome visitors.
