Spring isn't just a season. It's a shift in the air, a specific smell of damp earth, and, if you're reading the Song of Solomon, it's defined by a very specific noise. You’ve probably heard the phrase "the sound of the turtle is heard in our land." It sounds poetic. It sounds peaceful. But honestly, if you’re picturing a literal hardshell reptile poking its head out of a pond and let out a piercing screech or a low bellow, you’re looking at the wrong animal.
Turtles don't really sing. They hiss, sure. Sometimes they grunt when they’re mating, which is less "biblical poetry" and more "awkward nature documentary."
The "turtle" mentioned in that famous verse is actually the turtledove (Streptopelia turtur). It’s a small, migratory bird. When people talk about the sound of the turtle, they are talking about the deep, vibrating "tur-tur" call that signaled the arrival of spring in the ancient Near East. It’s a sound of return. It’s a sound of survival.
Why a Bird Was Called a Turtle
Language is weird. In Middle English, the word for this bird was "turtle," derived from the Latin turtur. It’s an onomatopoeia. The bird literally says its own name. Over time, as the word "turtle" became the primary name for the shelled reptiles we know today (which used to be called tortoises or terrapins more distinctly), the biblical translation stayed frozen in time.
If you open a King James Bible today, you’ll still see it. "The flowers appear on the earth; the time of the singing of birds is come, and the voice of the turtle is heard in our land."
Most modern translations, like the NIV or the ESV, have swapped it out for "turtledove" to avoid the mental image of a vocalizing snapping turtle. But the original phrase stuck in the cultural craw. It’s become a metaphor for renewal. When the turtledove returns to Israel or the Mediterranean basin in the spring, it isn't just a bird showing up. It’s a biological clock hitting 12:00. These birds are strictly migratory. They vanish in the winter. Their return is a guarantee that the harshness of the season is over.
The Biology of the "Tur-Tur"
The sound itself isn't a song in the way a nightingale or a robin sings. It’s a rhythmic, purring coo. It’s low-frequency.
Ornithologists note that the European turtledove has a very distinct vocal profile compared to the common pigeons you see in city parks. The common woodpigeon has a five-note call that sounds like it's saying "My toe bleeds, Betty." The turtledove is much more subtle. It’s a vibrating, rolling sound.
- Frequency: Usually between 400Hz and 600Hz.
- Duration: Each "tur" lasts about half a second.
- Purpose: Primarily territorial and for mate attraction.
Interestingly, these birds are now in serious trouble. According to the RSPB and various European conservation groups, turtledove populations have plummeted by over 90% in some regions since the 1970s. Intensive farming, the loss of hedgerows, and hunting along their migration routes through the Mediterranean have made the sound of the turtle much rarer than it was in biblical times. When we read these old texts, we’re looking at a world that was significantly louder with avian life than our own.

Cultural Weight and Symbolism
In the Song of Solomon, the sound of the turtle is used to describe the awakening of love. It’s sensual. It’s earthy. It’s about the earth coming back to life.
But it’s not just the Bible.
In various cultures, the turtledove became a symbol of fidelity. Why? Because they were believed to mate for life. (Reality check: they are generally monogamous during the breeding season, but like most birds, "forever" is a bit of a stretch). If one died, it was said the other would never take another mate, often sitting on a dead branch to signify its grief. This made the sound of the turtle a bittersweet one in some literary traditions—a sound of devotion that bordered on the tragic.
You see this in Shakespeare. You see it in the works of the "Phoenix and the Turtle." Again, he's not talking about a bird falling in love with a sea creature. He’s talking about the turtledove.
Misinterpretations and the "Singing Turtle" Myth
Let’s talk about the actual reptiles for a second because people genuinely search for this. Can a turtle make noise?
Yes. But you wouldn't call it a "sound of the land."
The Leatherback sea turtle can let out a sighing or belching sound when it's under stress on land. Some tortoises make a high-pitched squeak during mating. The Red-eared slider might hiss if you startle it. But none of these sounds are melodic. None of them signal spring.
The confusion comes entirely from the evolution of the English language. In the 1600s, "turtle" meant bird. By the 1800s, "turtle" meant reptile. This creates a fascinating linguistic gap where a reader in 2026 sees a word and perceives an entirely different animal than the author intended. It’s a reminder that words are fluid.

The Migration Pattern: A Feat of Nature
The reason the sound of the turtle was so significant is the sheer distance these birds travel. They winter in sub-Saharan Africa—places like Mali, Senegal, and Burkina Faso. Then, they fly thousands of miles, crossing the Sahara Desert and the Mediterranean Sea, just to reach their breeding grounds in Europe and the Middle East.
When they arrive, they are exhausted. They find a thicket. They start to coo.
For an ancient farmer, hearing that first purring "tur-tur" was better than a weather forecast. It meant the rains were ending. It meant it was time to plant. It was a biological certainty in an uncertain world.
The Sound of the Turtle in Modern Music and Literature
You might have stumbled upon the 1968 film The Sound of the Turtle or various jazz compositions that use the title. They are almost always referencing the biblical verse. It’s a shorthand for "the end of winter."
In the novel The Sound of the Turtle by John van Druten (which was also a play), the title is used to evoke a sense of unexpected spring in the middle of a messy, complicated world. It’s about people finding a new season in their lives.
Identifying the Call
If you're out in the wild—specifically in southern England, southern Europe, or the Levant—and you want to hear it, you have to look for specific habitats. They like "scrubby" areas. Think overgrown hedges, hawthorn bushes, and proximity to water and grain fields.
- Listen for a repetitive, two-syllable purr.
- Look for a bird smaller and slimmer than a city pigeon.
- Note the "tiger-stripe" patch on the side of the neck.
- Check the tail; it has a distinct white edge when they fly away.
It’s a shy bird. Unlike the bold pigeons that will steal a fry from your hand, the turtledove stays tucked away. You usually hear the sound of the turtle long before you see the bird itself.
Conservation: Will the Sound Vanish?
It's actually a bit grim. If we don't change how we manage land, the "voice of the turtle" might actually disappear from the land. In the UK, the "Operation Turtledove" project is a massive effort involving farmers, scientists, and volunteers. They are planting specific seed mixes (like fumitory and red clover) to ensure the birds have something to eat the second they land after their trans-Saharan flight.

The issue is that they need "dirty" farms. Modern, hyper-efficient farms are too clean. No weeds means no seeds. No seeds means no birds.
If you want to support the return of this sound, it usually comes down to supporting wildlife-friendly agriculture and protecting the migratory corridors. It's a global effort for a local sound.
Actionable Steps for Bird Enthusiasts and Readers
If you want to connect with this topic more deeply than just reading an article, there are a few things you can actually do.
First, go to Xeno-Canto or the Cornell Lab of Ornithology’s Macaulay Library. Search for Streptopelia turtur. Listen to the recording. It sounds nothing like what you expect if you’re thinking of a "turtle," but it sounds exactly like what you’d expect for a "coo."
Second, if you’re a gardener or land owner in a region where these birds migrate, stop being so tidy. Leave a patch of wildflowers. Avoid pesticides that kill the seeds they rely on.
Third, the next time you hear someone mention the sound of the turtle, you can be that person who explains the 400-year-old linguistic mix-up. It's a great "did you know" fact for a hike or a book club.
Finally, keep an eye on migration maps during the months of April and May. Websites like BirdLife International provide real-time updates on migration patterns. Seeing the sheer scale of the journey these birds take makes that low, vibrating coo sound a lot more impressive. It isn't just a noise; it's a victory lap.
