Warren Lake is currently a gull hotspot, due to large fish population with a large flock of common mergansers and common Goldeneye bringing fish to the surface. Furthermore, there seems to be many dead fish frozen in the ice sheet at the west end. The smorgasbord is attracting 500-600 gulls present throughout the day. The area is private. However birders are welcome at the lake. Just use common sense. Stay off residential properties.
Gull numbers are as follows:
Ring-billed Gull - 500 (99% adult)
Herring Gull - 20 (40% adult)
Iceland (Thayer's) Gull - 10-15 (10% adult)
Lesser Black-backed Gull- 6-10 (40% adult)
Glaucous Gull -1 immature
Great Black-backed Gull-1 immature
Mystery gulls-10 or so.
The mystery gulls are mostly immature gulls that are
somewhat atypical. Most of these are probably Herring Gull hybrids such as "Nelson's" Gull (with Glaucous) and "Cook Inlet" Gull (with Glaucous-winged). Today there were two first-Year large gulls that resembled Glaucous-winged and one that resembled Slaty-backed. Better photos are needed to confirm these.
