I learned this morning that the Sabine's Gull was still present yesterday, 12 October. Al Pochek has sent some awesome photographs, which are visible at

I don't know if the gull has been seen today. If you have any information on its status today, please let me know so I can share the news. Be assured that I will post updates as soon as I receive them, as I know there is substantial interest in the bird and people are trying to plan their weekends.
