The annual flight of Ross's Gulls past Barrow was a bit sluggish in arriving this year, but today the birds began to flood past in numbers. A single bird flew down the beach late this morning, which was the first Ross's Gull seen here since a lone bird flew past on October 5th. This despite the diligence of several birders watching all week. This morning's first Ross's Gull was followed by 9 more within the hour, and by 1 pm they were flying by constantly. In a 45 minute period (around 1pm) we tallied 510. Most of these were seen with naked eye or just binoculars and if you were to scan with the scope you could seen many more on the horizon. The flight slowed down a bit by late afternoon but smaller numbers of birds continued to fly by for the rest of the day.
