Annual Eagle Count

The Annual Eagle Count is a nationwide event that is coordinated locally by the Idaho Department of Fish and Game, and takes place during the first full week in January.  Snake River Audubon has long participated and has been monitoring a 3.5 mile stretch of the Henry's Fork from Ponds Lodge and the Island Park Dam through the woods and along the river to the junction of the Harriman State Park ski trail.  Watch our Home page for the official date and details for participating.

Also, more about eagles: Camas National Wildlife often has 50-100 bald eagles roosting in the trees around headquarters mid to late winter.  In March Snake River Audubon usually has a late afternoon field trip to watch the eagles come in.  It is spectacular.  Watch the Home page for details.

January 9, 2016:  Good turnout again this year.  Excellent snow! Not too cold.  There were 2 adult bald eagles sighted.  Although this seems like a small number, we have to keep in mind the eagles are highly mobile and can have a very wide home range.  A low number one year can not be interpreted as a real population change.

January 10, 2015:  Good turnout this year.  After considerable milling around we learned from a Pond's Lodge waitress that they had not served breakfast for at least 3 years... (maybe we were dreaming in previous years?)  So we decamped to The Trout Hunter down the road at Last Chance, where surprised and overwhelmed, but cheerful enough waitresses got us breakfast.  Snow was good, though a little icy under the trees.  Weather was mild and just below freezing all day with no wind, so the snow stayed good and we didn't freeze.  At the end of the day, and after considerable debate, we agreed there were 4 adult bald eagles along the lower Buffalo River and Brimstone Trail loop down the Henry's Fork.  No young birds again; I don't know whether that reflects a dip in eagle reproductive success in this area, or that young birds go somewhere else in winter.  
Also saw:
  • Common goldeneye (No Barrow's which are usually more common)
  • Mallards
  • Possible pintail
  • At least 12 Trumpeter swans, only a few cygnets
  • Downy woodpecker
  • Clark's nutcracker
  • Ravens
  • Dipper below the Island Park Dam
  • Lots of Chickadees

January 11, 2014:  Only two skiers braved the weather and reported three adult Bald Eagles in the Boggy Spring section of the trail out from Pond's Lodge.
