Join Flathead Audubon Conservation Educator Denny Olson for an early spring hike through the Owen Sowerwine Natural Area (OSNA) on Sunday, April 24th from 9 am until noon. The group will be searching for early river bottom and waterfowl migrants. Along the trails, Denny will explain the unusual hydrology and plant succession dynamics that have shaped this rare Montana environment. Many species of ducks, geese and swans should be moving through or searching for nesting spots. The resident Pileated and other woodpeckers will be doing residential construction, and early songbirds should be very visible immediately before the leaves come out. If you want to brush up on your birding by ear, Denny can repeat many of the songs you will hear to assist learning them well. Bring binoculars, rubber-bottomed boots and dress for the forecast. Call Denny at 249-3987, or contact at auduboneducator@gmail.com to register and get directions.
