X is by far the rarest starting letter in the bird world, rarer even than Q or U, but a small number of genuine species do carry it, mostly tied to scientific or regional names rather than everyday English. This guide sticks strictly to verified bird names that start with the letter ‘X’, rather than inventing entries to pad out a list.

The birds that start with ‘X’ for preschoolers and kids included here are real, documented species, even if some are only known by their scientific-style common names. Learning these ‘X’ letter bird names is less about building a long list and more about showing kids that even the rarest letters have something genuine behind them. Here’s what X actually has to offer.
List Of Bird Names That Start With ‘X’
Unlike most letters, birds beginning with ‘X’ exist mainly because of Greek-derived scientific naming rather than common folk names. Below are the verified species this guide could confirm, along with facts and sightings for each.
1. Xantus’s Hummingbird
Xantus’s hummingbird is a small, striking bird known for its bold white eyebrow stripe and rusty-orange tail feathers.
Did You Know?
- Xantus’s hummingbird is one of the very few hummingbird species found almost exclusively in one specific region.
- It feeds mainly on nectar, supplementing its diet with tiny insects.
- Males display a glossy green back that contrasts sharply with their pale underside.
- The species is named after John Xantus, a 19th-century naturalist who documented wildlife in the region.
Where You Might See: Xantus’s hummingbirds are found almost exclusively on the Baja California peninsula in Mexico.
2. Xantus’s Murrelet
Xantus’s murrelet is a small seabird known for its black-and-white colouring and habit of nesting on remote, rocky islands.
Did You Know?
- Chicks leave the nest and head out to sea within just a couple of days of hatching.
- Xantus’s murrelets spend almost their entire lives at sea, only returning to land to breed.
- They are considered a vulnerable species due to predators introduced to their nesting islands.
- Like the hummingbird above, this bird is also named after naturalist John Xantus.
Where You Might See: Xantus’s murrelets breed on islands off the coast of California and Mexico’s Baja Peninsula.
3. Xingu Scale-backed Antbird
The Xingu scale-backed antbird is a small, dark rainforest bird known for following army ant swarms to catch insects stirred up by the ants.
Did You Know?
- This antbird doesn’t eat the ants themselves; it feeds on insects and small creatures fleeing the ant swarm.
- It is named after the Xingu River region in Brazil, where it was first documented.
- The species relies on dense, undisturbed rainforest, making it sensitive to habitat loss.
- Its scaled-back pattern helps it blend into the shadowy forest floor.
Where You Might See: Xingu scale-backed antbirds are found in rainforests along the Xingu River basin in Brazil.
4. Xinjiang Ground Jay
The Xinjiang ground jay is a pale, desert-adapted bird known for running across open sand rather than flying when disturbed.
Did You Know?
- This ground jay is well camouflaged, with sandy-coloured feathers that match its arid habitat closely.
- It prefers running swiftly across open ground over taking flight, similar to a roadrunner.
- The species is named after the Xinjiang region of China, where it is most commonly found.
- It feeds mainly on insects and small reptiles found in the desert.
Where You Might See: Xinjiang ground jays are found in the arid deserts of Xinjiang province in northwestern China.
5. Xavier’s Greenbul
Xavier’s greenbul is a plain, olive-green forest bird known for its soft, whistling call heard more often than the bird itself is seen.
Did You Know?
- Like many greenbul species, it stays low and hidden within dense forest undergrowth.
- It feeds mainly on small fruits and insects found close to the forest floor.
- Xavier’s greenbul is considered a good indicator species for healthy, undisturbed forest.
- Its plain colouring offers almost no clues without hearing its call first.
Where You Might See: Xavier’s greenbul is found in forests across parts of Central Africa, including Cameroon and the Democratic Republic of Congo.
More ‘X’ Letter Birds
X doesn’t offer anything close to the long lists seen with other letters, and honestly, there isn’t a meaningful “more” category to add here. Every genuinely documented ‘X’ starting bird name this guide could verify is already listed above; padding the list further would mean including names that aren’t real or aren’t in common use.
Birds That Start With ‘X’ – Chart
Since what bird starts with the letter ‘X’ is such a narrow question to begin with, the short chart below has the five confirmed species.
FAQs
1. Why Are There So Few Bird Names Starting With ‘X’?
Very few English words of any kind begin with X, and bird names are no exception; most X-species exist because of scientific naming conventions or being named after a person, place, or river rather than a natural English word.
2. Who Was John Xantus, And Why Are Two Birds Named After Him?
John Xantus was a 19th-century naturalist who documented wildlife across parts of North America and Mexico, and both Xantus’s hummingbird and Xantus’s murrelet were named in his honour after he catalogued them during his fieldwork.
3. Why Does The Xingu Scale-backed Antbird Follow Army Ants?
This antbird doesn’t hunt the ants themselves; it follows the swarm because fleeing insects and small creatures are stirred up in the ants’ path, making them much easier to catch than searching alone.
4. Is The Xinjiang Ground Jay Related To The Roadrunner?
No, despite sharing a similar running behaviour, the two birds aren’t closely related; the resemblance is simply a case of different species evolving similar habits to survive in dry, open desert terrain.
Five real birds is a modest haul compared to most letters, but Xantus’s hummingbird and the Xingu scale-backed antbird prove that X still has genuine stories worth telling. Rather than stretch kids’ vocabulary with invented names, this guide keeps things honest; sometimes a shorter, accurate list teaches more than a longer one padded with guesswork.
