Norton Shores Banding, Coyote and Thrush


After I close the banding station at the Muskegon Lake Nature Preserve (usually in late November), I switch to netting in my Norton Shores backyard as acceptable weather and free time allow. Over the last five winters, the most common species have been Dark-eyed Junco (468), American Goldfinch (195), Northern Cardinal (59), Black-capped Chickadee (49), and House Finch (33). A few surprises sometimes occur (such as a Chipping Sparrow captured during February 2014), and overall, winter banding has yielded 19 species. This compares favorably to my average annual contribution of 16 species to the Great Backyard Bird Count.


Six species of neighborhood raptors (Sharp-shinned, Cooper's, Red-shouldered and Red-tailed Hawks, Merlin, and Great Horned Owls) put some pressure on the local birds, but mammalian predators, including cats, are fortunately much less common. However, this coyote examining the feeders on January 9 demonstrates that surprises are not limited to birds.


The smallest, but the most cold-hardy of the spotted thrushes in Michigan, the Hermit Thrush occurs chiefly during migration in Muskegon County. Based on captures from the fall banding station, the first birds appear during the last week of September, peak passage averages October 11, and most stragglers depart during the first week of November. However, some Hermit Thrushes breed in Muskegon County on conifer-dominated tracts within the Manistee National Forest. Moreover, while the species is not a regular winter resident, individuals may be found during even the worst winters, as long as sufficient stocks of berries persist (both native and exotic species are consumed). I have encountered solitary birds for the last three years, but this individual (on January 6) was the first for Black Lake Park. Its retained greater coverts indicate that it hatched last summer.

Wow! Awesome sightings! Where is Black Lake Park?
Thank you!

Black Lake Park is along the west side of Wood Road less than a mile south of Pontaluna just beyond the entrance to the Norton Shores leaf collection site. If the gate is open, park in the lot and walk the path west through the woods a short distance to the east shore of Black Lake. No need to backtrack because you can continue clockwise and walk either of two trails back around to the leaf collection area from which you'll see, and be able to walk to, your car. However, the gate may not be open or the lot plowed in winter. In that case, I'd park on Wood Road and walk the rest. Maybe someone who knows the winter procedure at BLP will post something here.
