Ok, so I live near the centre of the city and at our block of flats there is a small green area. There is a seagull who comes here and does the very same thing every night. This arrives around evening time and goes for a wander round the green area then stands face on to a path towards someone’s door, walks towards the door, stands about looking at it, wander back and forth then stands and stares at the door from the end of the path for a while and repeats. It’s been happening for around 2 months every night, maybe more I might have just not noticed. It even opens its beak while standing and silent makes a noise. Strange question but was kind of baffled by the behaviour. There is no nest apparent nearby and it doesn’t fly to or from it, plus it’s been possibly more than 2 months. I’d be interested to know if there is a common reasoning for this or if it is maybe down to lost nest or something?
