When the breeding season begins in our part of Herefordshire the local mallards and Canada geese start to do something that they don't do at any other time of year: something that I have never come across prior to living here. They land on the ridges of the houses and stand there surveying the area round about. Why do they do it? Perhaps they are displaying themselves as "available". Maybe they are advertising their claim to the area. Whatever the reason, it looks most odd. A quick flip through Google images shows that it is not uncommon, but is unusual enough for people to photograph the phenomenon.
