The early morning temperatures are in the mid 60’s under hazy skies as I begin hiking east on a section of the Meijer Bike trail within the 14-acre Stearns Preserve, located in the village of Riverdale, Michigan. As a volunteer monitor for the Chippewa Watershed Conservancy, I’m doing my annual walk-through and subsequent report of the preserve to make sure it complies with CWC’s definition of suitable wildlife habitat. Even though I’ve walked this part of the trail dozens of times, I’m surprised at the sight of a few smooth, gray, Beech-like tree trunks. After observing the Maple-type leaves on their branches, I determine they are never-before-realized, Norway Maple trees. Continuing east across a bridge over the Pine River, I pause to watch its water flow gently south. Up ahead, I spot ripening fruit on a Silky Dogwood shrub and the unripe fruit on a Wild Grape vine. The vine also displays some shrunken leaves with tiny galls caused by Phylloxera, a native, sucking aphid-like insect (stock photo). This condition does not seem to impact the quality and quantity of the grapes. Nearby, I come upon a familiar mushroom, called Chicken-of-the-Woods, Since it is soft and moist to my touch, I know it is quite edible. However, it’s important to cook this fungus thoroughly, as it can be difficult to digest raw. It's often used by foragers in stews and pasta dishes as a plant-based substitute for chicken due to its meaty texture and flavor. Further along, I spot a 2-inch, Northern Pearly-Eyes Butterfly perched on a tree trunk. These butterflies are unusual because they lack the long, sucking mouth parts needed for pollination. Instead, they feed on sap, dung, and decaying matter rather than nectar from flowers. Their 1-inch caterpillar (stock photo) feeds on a variety of wild grasses. Next, I notice a tiny, ¾ inch Common Angle Moth resting on a leaf. The caterpillar of this typical geometer moth (stock photo) can be seen “inching” its way along branches. They primarily feed on leaves of maple, oak, and birch trees. In some cases, this leads to defoliation, which can weaken trees and potentially kill young saplings. After spotting the CWC boundary marker, I turnaround to retrace my steps back toward the car and pause to listen to the cat-like mewing call of a Northern Catbird that gives this species its common name. However, these birds are also known to mimic the calls of other birds and even other sounds like frog calls or mechanical noises. Their vocalizations are diverse and can include whistles, squeaks, gurgles, whines, and nasal tones. Near the car, on the north side of the bike trail, I explore a small meadow where blossoms of Blue Vervain and Joe-Pye Weed catch my eye.

Welcomed sight

Pleasant sound

Carving the earth

Shaping the ground

Channel is full 

Current is swift

Burgeoning banks

Nature’s gift

Living water

Worthy of praise

Pine River

Admire her ways

It's early afternoon under sunny skies and temperatures in the mid 80’s, when Caroline, Riley and I hike a trail through the Tualatin River Wildlife Refuge, near Sherwood Oregon. This place spans 1,856 acres, including wetlands and lowlands, providing habitat for a diverse range of wildlife. Following the trail, I hear the familiar song of a House Finch (stock photo). Approaching a large pond, I spot both a dark, Great Blue Heron and a white, Great Egret. Herons are year-round residents in Oregon. While they don't undertake long-distance migrations, they may move to lower elevations or coastal areas during the winter,. Egrets are partial migrants, meaning some individuals migrate while others remain resident. Near shore I spot a foraging Nutria. These beaver-size rodents are an invasive species, causing damage to wetlands and agricultural areas. With no license or limit required, Oregonians are encouraged to hunt and eat them as a way to control their population. The meat is considered a cheap and available source of protein. Some people describe the taste as similar to rabbit or the dark meat of a turkey. Looking skyward, I see a perching Tree Swallow. These birds are common summer residents in Oregon, particularly near wetlands and waterways. They are long-distant migrants that soon will gather in large flocks before heading south. These swallows are thought to migrate along the Pacific coast and eastern Rockies. While some winter in the southern United States, many continue south to Central America and the Caribbean. Next to the path, I pause to watch yellow button-like blossoms of Common Tansy sway in the breeze. Up ahead, I notice the tiny, pink blossoms of Slender Centaury, a plant native to Mediterranean Basin of Africa, Asia and Europe. Down the trail, I come upon a Snowberry shrub displaying clusters of white, pea-size berries. While the fruit is not poisonous to birds and other wildlife, it can cause stomach upset in humans if ingested. Nearby, I spot an Oregon Grape plant with its holly-like leaves and clusters of small, blue-black berries that are edible but tart and are a favorite of birds and other wildlife. Close to the car, I observe an Oregon White Oak tree with some pool-ball size galls attached to a branch. Previously, a small wasp (stock photo) deposited eggs on the branch, inducing the formation of these galls around the larvae who then feed on the inner tissue. After the larvae pupate in late summer, they bore their way out of the gall, fly off to lay eggs in other trees to repeat the cycle.

Why do I walk in distant lands

Hiking trails in rain or shine

Why do I get up early and go

Start before the stroke of nine

What brings me to these places

With wetlands, river and hill

What draws me to the wild

There’s a need I wish to fill

My spirit connects to nature

Feelings for her are strong

Another place on earth

She’s been waiting all along

The early morning weather is clear and cool as Caroline, Riley and I follow a walking Western Gull along the rocky and sandy Oregon seashore. Since the tide is low, a variety of marine creatures are on display among the huge rocks and tide pools. A closer look at the rocks, show a surface covered with dark-colored, clam-like California Mussels mixed with light-colored Goose-neck, Acorn and Little Brown Barnacles. Mussels and Barnacles are filter feeders and compete for space and resources. Some are harvested for seafood. Coming upon one of many tide pools, I spots some colorful Ochre Sea Stars. These starfish display color polymorphism, where different colors exist within the same species. The orange color comes from a diet of Mussels, rich in orange pigments while the reddish and brown colors come from a more varied diet. Ochre Sea Stars are voracious predators on Mussels. By killing large numbers of them, they determine to some extent their distribution. Mussels are superior competitors for space and may take over the rocky substrate, but the presence of these Sea Stars allows other animals to use the space that is void of Mussels. In addition to starfish, I notice some small greenish-brown Aggregating Anemones. They use bits of shell and sand to camouflage themselves, making them blend into their surroundings. They can have "war" with other colonies using specialized tentacles. Under the water, I spot a 2-inch Tidepool Sculpin. This fish has several adaptations that allows it to thrive in these conditions. It can breathe air for short periods when out of the water, helping it survive when the tide recedes. It can change color to match its surroundings, making it difficult to spot. Sculpins are predators, feeding on small invertebrates like isopods, amphipods, and worms. Continuing to explore the beach, at my feet, I observe one of many Sand Fleas. Often called beach hoppers, these ¼ inch organisms are not insects, but small Crustaceans. Looking up at a steep rock face, I spot white blossoms of Coast Angelica and a Pelagic Cormorant standing on its nest that it cemented to the rocks with its own white guano (feces). Looking seaward, I notice a large mat of floating Bull Kelp. This species forms dense underwater forests that are particularly important for providing food and shelter for various species and are known to be essential to Oregon's coastal fisheries. However, these forests are facing decline due to warming waters and overgrazing by sea urchins, highlighting the need for conservation efforts. 

Peak of summer

Here in the west

Exploring nature

Remains my quest

Endless ocean

Rocky beaches

A pelican dives

A whale breaches

An osprey soars

Higher than most

Pounding surf

Carves the coast
