The Portneuf Valley Audubon Society and friends' annual holiday party, held with Watershed Guardians, will start at 6 p.m. Dec. 12 in the Pocatello Elks Lodge.

In addition, the Pocatello Christmas Bird Count is Dec. 14, and the American Falls Reservoir Christmas Bird Count is Dec. 28. There will be a Snake River eagle count on Jan. 11.

The PVAS and friends holiday dinner itself will start at 6:30 p.m. The Elks Lodge is at 410 S. Main St. in Pocatello. The well-lighted entrance is in back with ample parking and handicap access. PVAS will serve a holiday ham for the entrée, and the rest is potluck. There is a no-host bar for beverages and plug-ins for hot dishes.

The event will feature a "White Albatross" gift exchange (White Elephant exchange for non-birders). Please bring a wrapped, gently used birding or nature-related item to exchange.

The Pocatello Christmas Bird Count on Dec. 14 covers a 15-mile diameter circle around the Gate City that extends from Blackrock Canyon to Siphon Pond. The American Falls Reservoir Christmas Bird Count on Dec. 28 includes Michaud Flats, the Fort Hall Bottoms, McTucker Springs, Springfield and Aberdeen areas.

To volunteer and be assigned to a group for either or both bird counts, contact ISU Professor Emeritus Chuck Trost at 208-233-4538. Bird feeder watchers in Pocatello should call Trost with results after 6:30 p.m. Dec. 14.

This is the 120th annual Christmas Bird Count. It is the longest-running citizen science survey in the world. It provides critical data on population trends of birds. Thousands of participants have a lot of fun while collecting data that is used by many researchers to protect birds and their habitats. For information on the count, visit bit.ly/37ZPrFk.

On Jan. 11, PVAS leaders will lead the eagle count field trip from American Falls Dam downstream to Raft River. Most of the count will be done from vehicles, although participants will walk to the Snake River at available access points, so participants should dress for the weather and bring some snacks and a friend.

To participate in the Jan. 11 field trip, meet at 8 a.m. in the Idaho State University campus parking lot by the bison sculpture behind the Idaho Museum of Natural History Building on South Fifth Avenue and East Dillon Street.
