I went to a beach town not too long ago and I can still remember the cacophony of seagulls.
Those were the garbage pickers, hanging around town. I didn't hear one gull while I was there. I've been there in winter, summer and spring. Different concentrations of gull population, but rarely the noisy gulls you describe. Mostly they just hunt for food. Constantly. If humans are eating, they'll come around begging.
I liked those houses too. Not typical for this area.
