I wouldn't say social colony since none are ever seen together except for the pair but I'd say that the buildings and biomass density allow far closer coexistence then the natural habitat therefore higher densities are able to coexist? In other words, the grass is greener on this side of the concertina.
I might check certain orchards more though landmines are still found in some. Also if I hear of any corpses found, I'll try to take good pics and on items that might make this species more identifiable.
I haven'theard any accounts of any in trees but the smaller ones especially climb the varying baricades, etc alot. Some might raid birds nests?
There are a bunch of birds to include small passerines, house crows, common mynas and various doves and pigeon species.
Bird highlight so far over here:
