WHy are there so many birds suddenly gathering around my house?

We don't have a bird feeder, or birdboxes. but recently there have been several species of birds coming to nest in our window sills (we have a wall of a bunch of windows, and now there at 3 birds nests in them) also, birds will continuously throw themselves up against the glass. i woudn't be so freaked, but the birds are all diffrent kinds. as i write this now i am listening to two diffrent birds throw themselves against a window. I don't mind this...it just strikes me as odd. and it has never happened before in all of the years i've lived here. anyone have any answers?

1. Maybe you smell like fish. Are they seagulls.
