Wildlife Watching:

The large lake, abundant wetlands, old fields and mature forests provide a diversity of habitats that attract wildlife in all seasons. Once pushed to the edge of extinction, bald eagles and ospreys have rebounding populations. Both of these fish-eating raptors nest near Lake Wilhelm. The combination of old fields and mature forests are home to many birds including American woodcock, common snipe, common nighthawk and many species of warblers. In the spring and fall, waterfowl by the thousands stop at the lake for a quick rest and snack. Loon, teal, merganser, goldeneye and bufflehead are some of the noteworthy waterfowl. The winter is a good time to see many woodpeckers, including the pileated woodpecker.

In summer, turtles are abundant in the quiet waters by the Marina. The wetland across Lake Wilhelm Road from the marina entrance has a waterfowl observation station and is a great place to see osprey and beaver.

Bluebird trail:

Once a rare bird due to habitat loss, the red, white and blue eastern bluebird is once again a common sight at Maurice K. Goddard State Park. The park’s bluebird trail program is one of many successful wildlife programs at Maurice K. Goddard State Park. The habitat in Mercer County is very suitable for this beautiful bird but was lacking cavities for the birds to nest in. For over 20 years, volunteers have maintained bluebird nesting boxes in old fields, meadows, farm fields and recreation areas. Six volunteers maintain about 90 boxes each year, which annually fledge about 100 young bluebirds. The white and emerald tree swallow, another cavity nester, also thrives in the boxes.

Purple Martin

: Nesting gourds have been set up for the Purple Martin. The destruction of its insect prey by Hurricane Agnes, in 1972, decimated and fragmented the population of purple martins. What was once a common bird became hard to find except in a few places. Highly social birds, purple martins need abundant cavities to form colonies.

The best place to see the birds and boxes is in day-use areas along the Multi-use Trail, which traverses the lower portion of Lake Wilhelm, and the Marina and boat launches.

Mercer County is filled with a variety of scenic trails, waterways, parks, and more, perfect for families and avid outdoor adventurers to enjoy! If you are ready to plan your visit, go to today to get started!
