These Northern Lapwings are displaying in the morning.
First, two birds, probably male and female, perform courtship displays in four phases.
In the first phase, they perform wing movements while they circle around each other.
In the second phase, the male jump in front of the female with open wings and displaying the chestnut undertail coverts, while she bows.
The third phase shows both birds walking together side by side.
In the fourth phase, the male performs lateral display while moving the wings, in order to expose the bright colours of the glossy plumage. The female looks at him motionless.
Then, they display again with the same phases.
While these birds are displaying, a third Northern Lapwing is bowing repeatedly, exposing the chestnut undertail coverts, at about 5 metres from the others.
There probably are two males and one female. The males perform the most part of the displays while female look at them. But she was more interested by the first male and displayed with him, without any interest for the second!
