Gulling before it's gone

Despite the new arrival, I have managed one to two brief birding trips out, although these haven't yielded much of note. However, I'm painfully aware that Cotham Landfill is rapidly filling up, and that after this winter, local gulling opportunities are going to be seriously curtailed. So, I'm going to somehow need to make the time to visit the site during the week, when the tip is operational... I managed an hour there yesterday morning on the way into work. There were maybe 500+ large gulls present. No Casps and no white-wingers, but a big 1st winter Yellow-legged Gull was an eye-catching bird, and there was the usual smatter of yellow-ringed Herring Gulls originating from York, plus a white-ringed Black-headed Gull that I need to track down.
