Gulls on Pasture

Driving around near Heise found this pasture  with RBGulls coming and going. What could they possibly be feeding on in an 80 foot circle?  Couldn’t see them actually picking up anything. Over 100 on center pivot and another 40-50 picking through the breast high grass. Other than that best bird was couple of Townsend Solitaire.

Re: Fall Waterfowl Migration

A fair number of Trumpeters overwinter along the Snake River of SE ID. I’ve seen groupings with 30+ birds & 5-6 groups at a time grazing along neighbor’s winter wheat field. His ground is back in winter wheat, so should attract Trumpeters, as soon as the snow flies. The Tundras mainly flyover & numerous numbers at night, as David Pace responded. I enjoy listening to their “flyover chatter” on a cold, crisp night!

Fall Waterfowl Migration

During the past week, seeing daily flights of Trumpeter Swans, Canada Geese & Snow Geese (one group with a single dark morph “Blue Goose”). The Trumpeters are mainly arriving birds which will winter along the Snake River & surrounding farmlands. Trumpeter numbers are noticably increasing daily. Haven’t seen, nor heard, any Tundras yet.
