May 25

The early morning temperatures are in the mid 60’s under sunny skies and a refreshing south breeze as I find myself standing in St Louis Michigan’s Penny Park watching parent Canada Geese tending to their goslings on the grassy shore of the Pine River Millpond. Hiking west along the riverbank, I spot a patch of Field Peppergrass and a nearby patch of Swamp Buttercup swaying in the breeze along with ever present call of a male Redwing Blackbird. Further along, I notice some Wild Iris ready to bloom and a single plant of the highly invasive Garlic Mustard. Unless removed, this plant will spread very quickly forming dense colonies and outcompeting native plants for sunlight and moisture. Up ahead, I come upon a perching Eastern Kingbird. In the summer they feed on insects caught in mid-air ("flycatching"). Exploring the mowed path, my eyes are drawn to the tiny yellow blossoms of Wood Sorrel and the tiny pink blossoms of Herb-Robert. Looking back at the riverbank, I see a dried up stalk of an Adam’s Needle Yucca plant. This cultivated plant (stock photo) most likely escaped from a residential lawn. Walking close to patches of cattails along the shore, I’m not surprised to see and hear several male Redwing Blackbirds defending their nesting grounds. Likewise, I’m not surprised to see a few female Redwings perching above their nests, often located in the cattails close to the water (stock photo). Standing here, I look out at this millpond to the place where the infamous Michigan Chemical company (Velsicol) once stood and where since 1998 massive efforts have been made to remove toxins from the surrounding land and water. While water quality has improved, it remains polluted and has negative effects on wildlife populations, like Redwing Blackbirds. Redwings that live here feed at several levels of the food web — insects, aquatic larvae, seeds and small snails — so contaminants can move upward and accumulate. Effects on reproduction include thinner eggshells, reduced hatching, fewer fledglings and lower chick survival. Contaminated habitats may lose reproductive success yet display plenty of birds like this place because they move in from other wetlands. Turning around and heading back to the car on this beautiful spring morning, it is impossible not to think about the harrowing history of this part of the Pine River. Hiking beside the moving water, hearing blackbirds calling in the wind while blossoms open all around me, I’m reminded again of nature’s persistence. Spring does not erase the past but quietly insists on renewal anyway.

Duck on the pond

Bird on the wing

Green on the ground

Season of spring

Flowers that bloom

Nettles that sting

Crows that caw

Season of spring

Sun to welcome

Rain to bring

Seeds to grow

Season of spring

The early morning temperatures are in the low 40’s under mostly cloudy skies, as I begin my weekly nature hike on private land in Gratiot County, between Riverdale and Elm Hall.Right away, I spot several 1-inch Eastern Tent Caterpillars crawling over their silky nest in the crotch of a small Cherry tree. Soon they will begin feeding on the new leaves. Heavy feeding can defoliate trees, but healthy trees usually recover by mid-summer. These caterpillars are a food source for many birds, including Robins, Cardinals, Red-winged blackbirds and Baltimore orioles. Stink bugs and ground beetles also prey on theses larvae. In about 6 weeks mature caterpillars will leave the tree to pupate. After 2-3 weeks of pupation, moths (stock photo) emerge from the cocoons. They live only a few days to mate and lay eggs for the next year. After passing a Honeysuckle shrub beginning to blossom, I come upon a large patch of Mayapples as some plants are displaying tiny oval flower buds. While the name implies they will produce “apples” in May, it will be June before fruit appears. Looking around, I spot another Mayapple plant with orange stain on its leaves. Called Mayapple rust, this is a common fungal disease affecting this plant. While disfiguring its leaves , it rarely damages the plant significantly. High in the crotch of a tall Oak tree, I spot the head of a young curious Raccoon. Probably a kit or juvenile, it most likely was born earlier this year. When 20 weeks old it becomes independent but often stays with the mother until next spring. The glowing eyes are just light reflection from the camera, common with raccoons because of the reflective layer behind their retinas. Up ahead, I notice a patch of Downy Yellow Violets and a 3-leaf Trillium plant yet to flower. On the ground, I spot a single Morel mushroom with its unique honeycomb design. This highly prized, edible fungi is known for its earthy flavor, and rarity, typically foraged in North America and Europe this time of year. Nearing the car, my ears perk up to the loud distinct song call of a Wood Thrush (stock photo).  This medium-size songbird feeds on the forest floor consuming insects, snails and fruits. Wood Thrushes migrate to Michigan in spring, arriving from Central America between the third week of April and the third week of May to breed. The species is listed as a “Species of Greatest Conservation Need” in Michigan, with populations declining due to forest fragmentation and brood parasitism by Cowbirds. Arriving at the car, I feel fortunate to witness another Michigan spring slowly coming alive.

Lifeblood of earth

Is what you bring

Your current calls

Your waters sing

Spring treasures

A garter snake

A school of fish

A Mallard drake

Vistas of beauty

Your banks bestow

Moving mirror

Pine River, flow

The midday temperatures are in the upper 50’s under partly sunny skies and a stiff west wind, while I pause on the high bank of the Bad River as its water flows gently below me. Up ahead, I spot a 10-inch Northern Map turtle basking on a log before it quickly slides into the water. This reptile is named for the intricate, map-like yellow lines on its grayish-brown shell that resemble contour lines on a topographic map (stock photo). On the far shore I spot another one of these turtles, resting on the muddy bank. Since it does not move quickly into the water, I’m thinking it’s a female laying her eggs. A single nest typically contains 6 to 20 oval, flexible-shelled eggs. While It takes 50 to 70 days for the eggs to hatch, most hatchlings dig themselves out and head instinctively toward the water. However, those that hatch late in the season may overwinter inside the nest and wait until the following spring to emerge. Exploring the floodplain, I come upon the shell of a type of freshwater mussel called a Giant Floater. While most of the flesh was likely consumed by a raccoon, some is still being decomposed by small flies. These mollusks act as nature’s water purifiers by filtering up to 10 gallons of river water per day as they feed on plankton and organic debris. Further along, I first hear the piercing call of a Baltimore Oriole and then follow a Mourning Cloak butterfly as it lands on the ground extending its upper wing surface. As attractive as the butterfly is when its wings are open, when they’re closed, they look like a dead leaf (stock photo). The gray and brown patterning on the underwing also lets the butterfly easily camouflage itself against a lot of tree bark where it overwinters having glycerol-based antifreeze in its blood to survive freezing temperatures. The name “mourning cloak” is a  translation of the German word referring to the butterfly's dark, velvety wings that resemble a traditional cloak once worn by people in mourning. Turning around, I notice blossoms of Woodland Violets on the ground and those of Common Hawthorn overhead. Near the car, I spot a Shagbark Hickory tree with one of its branches displaying new green leaves above unfolding reddish leaf bud scales. At the car, I pause and realize that spring is not simply about beauty returning to the landscape. It is also about resilience. New blossoms still emerge. New leaves still unfold. Birds still return and sing from unseen perches high in the trees. Maybe that is why spring always feels quietly hopeful to me. The season does not promise perfection. Instead, it offers another chance to begin again.

Creature lives

Creature dies

On the earth

There it lies

Decaying carcass

Joins the ground

Decomposers

Are always found

Flies and maggots

Beetles crawl

Flesh eaters

Plenty for all

The late morning temperatures are in the mid 40’s under mostly cloudy skies and a variable north wind, as I begin hiking in the Jailhouse Trail just south of Ithaca. Right away, I come upon a Red Squirrel Midden, a large pile of discarded conifer cones and cone scales at the base of a White Pine tree. A pile like this is created over years by a single squirrel.  It will tunnel into the Midden to create chambers where it caches fresh cones gathered in late summer for winter survival. From the trail, I notice patches of blossoming Daffodils growing on the forest floor. These wild patches are often indicators of abandoned homesteads, old cabins, or forgotten cemeteries. Because Daffodils are toxic to deer and other wildlife, they are rarely eaten, allowing them to naturalize and multiply over decades. On the damp ground, I spot a mound of mud that serves as the entrance to an underground tunnel system for a terrestrial burrowing crayfish (stock photo). Referred to as chimneys, they are made by digging a hole and depositing balls of mud around it. Used for accessing water, hiding from predators and reproduction, tunnels can extend 2 to 3 feet deep. Up ahead, I spot a large patch of Japanese Knotweed, a fast-growing, highly invasive plant known for its bamboo-like stems. This plant, native to Japan, China, Korea and Taiwan, is one of the most invasive plants in the world and is thought to be found on every continent besides Antarctica. In Michigan, it is a “prohibited species”. Under state law it is illegal to possess, introduce, sell, or grow Knotweed without a permit. Turning around, I examine the leaf litter where I spot a 1/3 inch Drumming Sword Wolf Spider. The spider's common name refers to the male’s courtship behavior. Upon finding a female, the male drums his appendages near the mouth and twitches his abdomen against dry leaves creating a purring or humming sound that can be heard up to 10 feet away. Off in the distance, I spot some fresh 12-inch diameter Pheasant's Back mushrooms growing on a decaying stump. While technically edible and non-toxic, this fungi is considered to have a poor taste and becomes very tough as it matures. Nearing the car, my ears perk up to the farewell call of a Northern Cardinal. By the time I exit the trail, I feel like I haven’t just walked through the woods—I’ve witnessed another shift in the season. Not dramatic, not loud, but steady and certain. Maybe that’s the real lesson from nature today. Sometimes it whispers through blossoms, breezes and birdsongs, asking only that I slow down enough to notice.

 

Shaded trail

Beneath the dome

Chipmunk retreats

To hidden home

On muddy ground

Ephemerals grow 

Spring Beauty

Puts on a show

Beams of sun

Break the day

Birdsongs resound

Beginning of May
