During the 1990s, Jim was a prominent figure in West Michigan’s birding and conservation communities. Alongside George Wickstrom, he spent the decade tracking migrations, conducting species surveys, and documenting avian populations across Ottawa, Muskegon, and Allegan counties. His detailed annual logs, titled "Looking Back," captured rich observations of local wildlife, seasonal nesting habits, and rare sightings. Of note is the report of Ottawa County’s first record of a Red-shafted Northern Flicker hybrid in 1996. He also embarked on dedicated birding trips, including journeys to Whitefish Point.
As a dedicated citizen scientist, Ponshair was a key participant in the National Audubon Society’s annual Christmas Bird Counts, gathering critical population data to support ongoing scientific research. Beyond fieldwork, he actively shared his passion with the public. In June 1993, he co-installed an educational Audubon exhibit at the Warner Baird Library and Grand Haven City Hall, featuring his own life-sized, hand-carved, and hand-painted sculptures of rare local birds alongside his original illustrations, collected nests, and owl pellets.
Ponshair also contributed significantly to community education and regional preservation efforts. He organized, edited, and illustrated the Grand Rapids Audubon Club’s guide, Favorite Birding Areas, served as a primary regional contact for local Audubon chapters, and actively supported historical institutions like the Muskegon County Museum.
