Your objective
By the end, you'll be able to explain what a plain yelp, tree yelp, and assembly yelp each communicate and describe how each one sounds, so you can recognize them in the field and decide which to throw at a gobbler.
It’s 5:40 a.m. and full dark. Somewhere above you in a pine, a gobbler is still on the roost. He hasn’t gobbled yet. You sit still, slate call in hand, and let the woods wake up — until, from across the hollow, comes a soft, rolling sound barely louder than a whisper: kee-yuk … kee-yuk … kee-yuk. A hen is checking in before fly-down. That sound — the yelp — is the first thing a turkey hunter learns to make, and the last thing a master calling champion stops refining. This is where it starts.

What the yelp means
The yelp is a contact call — the turkey equivalent of “I’m over here, where are you?” Hens use it constantly to stay in touch with a flock, to locate a gobbler, and to signal that they are receptive. Gobblers yelp too, but their versions are deeper and slower, and spring hunters almost never mimic them — the goal in spring is to sound like a hen.
When a gobbler hears a hen yelping, his instinct is to gobble back and wait for her to come to him (that’s normal turkey mating behavior — she walks to him). Your job as a hunter is to flip that script: yelp convincingly enough that he decides to come to you instead.
The why Why the gobbler should come to the hen — and why he sometimes does
In an undisturbed spring woods, hens seek out the dominant gobbler and walk to his strutting zone. The gobbler gobbles mostly to advertise his location and let the hens find him. Hunters exploit two things: (1) a henned-up gobbler may eventually hear a very insistent hen and break away to investigate, and (2) an unattached gobbler — one whose hens have gone to nest — is eager for any hen sound. The early season and mid-morning window, once nesting hens have left, are when yelping is most reliable at moving birds to you. Source: NWTF, The Sounds of the Wild Turkey.
The plain yelp: two notes, the backbone of turkey calling
The fundamental yelp is a two-note call. Every source — NWTF biologists, calling champions, field hunters — describes it the same way: a higher, cleaner front note that breaks down to a lower, raspier back note. Manufacturers often spell it “kee-yuk” or “chee-owk.”
Structurally:
- Front note (kee): higher pitch, slightly shorter.
- Back note (yuk): drops in pitch, with a raspy, hollow finish.
- Series: usually three to nine kee-yuk pairs in a row, with slight pauses between groups.
A single two-note kee-yuk is called one yelp. A string of several is a “series of yelps” or a “yelping sequence.” Cadence and spacing matter more than volume — a slow, deliberate series at moderate volume sounds like a content, unhurried hen.
Edge case Gobbler yelps vs. hen yelps
A gobbler’s yelp is deeper, coarser, and noticeably slower-paced than a hen’s. You’ll sometimes hear spring gobblers yelp while drumming or after a gobble — it sounds almost like a slow, gravelly version of the hen call. Hunters rarely imitate the gobbler yelp in spring; it can challenge dominant birds and is more of a fall-calling tool. If you hear a slow, deep yelp in the spring woods, you may be hearing a tom, not a hen. Source: MeatEater, The Six Turkey Vocalizations.
The tree yelp: same sound, different volume
The tree yelp is what you hear (and want to make) during that first pre-dawn window when turkeys are still on the limb. A roosted bird makes these calls with its beak nearly closed, which muffles the sound to a soft, tentative murmur.
Calling authorities describe it as “brief, soft, and muffled” at first, growing slightly louder as fly-down time approaches (NWTF, The Sounds of the Wild Turkey). The meaning hasn’t changed — it’s still “I’m here, where are you?” — but the volume says: I’m roosted, I’m calm, I’m not going anywhere yet.
For a hunter, the tree yelp is the first sound to make at first light. A few quiet series on a slate or diaphragm while the gobbler is still up can get him interested before he ever hits the ground — and occasionally committed before a competing hen gets his attention.
The assembly yelp: louder, longer, more insistent
The assembly yelp is the yelp turned up several notches in volume, length, and emphasis. The NWTF describes it as “a long, relatively loud series of yelps, usually a little more emphatic and longer than a standard series,” used by a boss hen to pull her flock together (NWTF, Assembly Yelping).
Think of it as the difference between saying “hey, where are you?” and “WHERE IS EVERYBODY — COME HERE RIGHT NOW.” The same two-note kee-yuk pattern, but:
- More notes in a series (sometimes a dozen or more).
- More volume — meant to be heard at distance.
- More urgency — a slight pleading quality, building in intensity.
In spring, a well-timed assembly yelp can break a hung-up gobbler or pull in a bird that’s been ignoring softer calling. It’s a tool in your bag, not your opening move — start soft and escalate.

Check your understanding
Knowledge check
A plain yelp is best described as which of the following?
Knowledge check
You're at your setup in the dark. The gobbler is still roosted. What is the purpose of starting with a few TREE YELPS rather than a full series of loud plain yelps?
Knowledge check
A gobbler has been gobbling across the hollow for twenty minutes but won't close the last hundred yards. You've been throwing soft plain yelps. Which is the BEST next move, and why?
Take it to the woods
The yelp is something you practice before the woods — the more it lives in your muscle memory, the more naturally it comes out when a bird is close and your heart is racing.

If you remember nothing else
- The yelp is the turkey's everyday contact call — 'I'm here, where are you?' — and it's the first call to master.
- A plain yelp is two notes: a higher 'kee' that breaks down to a lower 'yuk'. It's usually thrown in runs of three to nine notes.
- The tree yelp is the same sound but quieter and muffled — a roosted bird with its beak nearly closed, checking in before fly-down.
- The assembly yelp is louder, more emphatic, and drawn out — a boss hen demanding the flock come together.
- Gobbler yelps are deeper, coarser, and slower than hen yelps — but spring hunters almost never imitate them.
- Master the plain yelp first. Everything else in turkey calling is built on or around it.
