I stopped by North Teller #5 this morning to practice gull observing before their food source freezes for a couple of days.
Christian Nunes reported no gulls around 7:45 AM. There were a couple dozen there when I arrived an hour later. When I left at 11:00 AM, there were over 150 gulls there. All the gull arrivals I noticed were from the east. (Well, at least the last quarter mile of their flights came from the east.) The few departures I saw were also toward the east. Arrivals were an ongoing slow trickle, 1 or 2 at a time. The Glaucous-Winged x Herring arrived relatively early and stayed. A Lesser Black-Backed arrived late. There were also the usual few Thayer's gulls. Ring-Billed gulls outnumbered Herring Gulls only slightly. I did NOT see any Iceland-ish gulls this morning. A Prairie Falcon made a brief appearance on the northwest side of the "lake", and the trees on the north side had two subspecies of White-Breasted Nuthatch -- one Eastern and one Interior West.
