📖 Simple Line-by-Line Analysis
🌿 Lines 1–2: The Return of Gray Wolves
Explanation:
Gray wolves were reintroduced into Yellowstone National Park after being absent from the area.
As expected, the wolves began hunting deer and reducing their numbers.
This was the beginning of an important change in the ecosystem.
Poetic Device: Imagery – The return of wolves creates a picture of wildlife in the national park.
🌳 Lines 3–4: Trees Begin to Grow
Explanation:
Before the wolves returned, deer ate many young plants and trees.
As a result, the trees could not grow properly.
When wolves began hunting deer, the pressure on young plants was reduced.
Trees started growing taller than they had during the middle of the twentieth century.
Poetic Device: Imagery – The growth of trees creates a picture of nature recovering.
🐦 Lines 5–6: Songbirds Return
Explanation:
As trees grew taller, songbirds found suitable places to build their nests.
The birds also helped spread seeds.
These seeds encouraged the growth of smaller plants and bushes beneath the trees.
Thus, the return of wolves indirectly helped birds and plants.
Poetic Device: Imagery – Nesting birds and growing plants create a lively picture of nature.
🐇 Lines 7–8: Small Animals Return
Explanation:
The growing bushes provided shelter for snowshoe hares.
Weasels and water shrews also returned to the area.
The return of plants created suitable living conditions for different animals.
The poet shows how the recovery of vegetation supports other forms of life.
Poetic Device: Imagery – The description of small animals creates a picture of increasing biodiversity.
🦅 Lines 9–11: Birds of Prey Return
Explanation:
The recovery of the ecosystem attracted birds of prey.
Hawks, falcons, bald eagles and kestrels returned.
These birds found suitable habitats and food sources.
The poet mentions their shadows to suggest their movement through the sky.
Their return shows that the ecosystem is becoming healthier and more balanced.
Poetic Devices:
Imagery: The shadows of birds flying above the land create a visual picture.
Repetition: The repeated references to different birds and their shadows emphasise the variety of wildlife.
🦌 Lines 12–14: Deer Become More Cautious
Explanation:
The birds of prey hunt over small streams and channels.
Meanwhile, mule deer become more careful because wolves are present.
The deer can no longer move about without fear of predators.
They avoid places where wolves might surprise them.
This change in deer behaviour reduces the damage caused to young plants.
Poetic Device: Imagery – The frightened deer and hunting birds create a vivid picture of wildlife.
🐻 Lines 15–16: Bears and Beavers Return
Explanation:
As plants recovered, berries began growing in greater numbers.
The berries attracted bears.
Willow trees and other plants also began growing near the river.
These trees provided food and building materials for beavers.
As a result, beavers returned to the riverbanks.
Poetic Device: Imagery – The poet describes berries, bears, willows and beavers to show the recovery of nature.
🦫 Lines 17–18: Beavers Build Dams
Explanation:
The beavers began building dams in the rivers and streams.
These dams changed the movement of water and created new habitats.
Muskrats also came to the dams.
The dams supported more aquatic life.
This shows how the activities of one animal can benefit several other living creatures.
Poetic Device: Imagery – The dams and the animals living around them create a picture of a healthy river ecosystem.
🐸 Lines 19–20: Frogs and Water Insects Return
Explanation:
The new water habitats supported tadpoles and frogs.
The frogs began making sounds at night.
Water striders, which are small insects that move across the surface of water, also appeared.
The poet describes the return of sounds and movement to the river.
This suggests that the ecosystem is becoming more lively and diverse.
Poetic Device: Auditory Imagery – The sounds of frogs create a picture that appeals to our sense of hearing.
🐦 Lines 21–22: The American Dipper and Fish
Explanation:
The American dipper, a small bird that lives near rivers and streams, returned.
It moved around the fresh pools of water.
Fish also remained in the river.
The changes in the river environment created better conditions for different aquatic creatures.
Poetic Device: Visual Imagery – The movement of the bird in the fresh pools creates a clear picture.
🐻 Lines 23–24: More Animals Benefit
Explanation:
Bears began catching fish in the river.
They also hunted deer fawns.
Vultures and coyotes returned to the region.
These animals had been absent from the area for a long time.
Their return shows the growing variety of wildlife.
Poetic Device: Imagery – The poet describes the feeding activities of animals to show the natural food chain.
🌱 Lines 25–26: Seeds Spread and Plants Grow
Explanation:
Vultures and coyotes help scatter seeds through their droppings.
These seeds contribute to the growth of more plants.
Trees, bushes and berry plants begin growing along the riverbanks.
The poet shows that animals contribute to the regeneration of plant life.
Poetic Device: Imagery – The spreading seeds and growing plants create a picture of renewal.
🌊 Lines 27–29: The River Changes Its Course
Explanation:
Earlier, the river flowed almost straight and frequently flooded its surroundings.
The growing vegetation and the dams built by beavers changed the river environment.
The river began following a winding course.
According to the poem, these changes made the river less likely to overflow its banks.
This shows that the effects of the wolves' return extended beyond animals and plants to the river itself.
Poetic Device: Imagery – The winding river creates a picture of the transformed landscape.
❤️ Lines 30–31: The Poet Connects Nature with Her Life

The poet now directly addresses the reader.
She asks the reader not to say that the changes in Yellowstone are different from her own experience.
She believes that the transformation of the ecosystem is similar to the transformation in her personal life.
Just as the return of wolves changed the natural environment, an important event changed her life.

🌍 Lines 32–33: One Animal Changes an Entire Landscape

The poet explains that the return of one hungry animal led to the renewal of many forms of life.
The wolves' presence started a series of changes in the ecosystem.
These changes affected plants, birds, animals and rivers.
The poet emphasises that all living things are interconnected.
A change in one part of nature can influence many other parts.

👩👧 Lines 34–35: The Poet Becomes a Mother
Explanation:
The poet finally reveals the connection between the changes in Yellowstone and her own life.
She says that she rediscovered herself when she became a mother.
Motherhood brought a major transformation in her identity, emotions and understanding of life.
Just as the return of wolves changed the ecosystem, the arrival of a child changed the poet's life.
She was no longer the same person she had been before becoming a mother.
