Ok, heres the deal, i have what looks like a baby seagul on my bathroom flat roof which seems to be talking to a normal looking seagul on by back bedroom roof which is about ten foot high than the bathroom. Behind the normal seagul is another baby one.. Question is how can i get the baby one stranded on my bathroom upto the others?

I don't wanna go out there incase the normal one attacks me or something!?

Any Ideas?!
