When we built our house in a new housing estate, the plovers / masked lapwings would dive bomb and squawk during the egg laying period. The eggs were laid on the ground and hard to spot. They were usually in pairs.
14 years later, their population has increased dramatically, and the don't take any notice of humans. They just look at you and if you approach them, they retreat and look at you, no more aggression, and there are groups of them.
Before we were in their territory and they defended it, current ones are in our territory and have no concerns about our presence.
