5 Birds That Start With X
Birds whose names start with “X” are rare, and many are not widely known. However, these birds are just as fascinating as any other, with unique characteristics, habitats, and behaviors.
In this article, we’ll explore five such birds:
- Xantus’s Hummingbird
- Xavier’s Greenbul
- Xingu Scale-backed Antbird
- Xinjiang Ground-Jay
- Xolmis (Genus of Tyrant Flycatchers)
Each of these birds offers something unique to the avian world, from dazzling plumage to intriguing behaviors. Let’s dive into their characteristics, habitats, and why they are special.
1. Xantus’s Hummingbird (Basilinna xantusii)

Appearance and Features
Xantus’s Hummingbird is a strikingly beautiful bird native to Baja California, Mexico. It has a shimmering green back, a white chest, and a distinct black mask with a white stripe above its eye. The male sports a vibrant reddish-orange beak with a black tip, adding to its charm.
Habitat and Behavior
This hummingbird prefers coastal regions, semi-arid scrublands, and pine-oak forests. It feeds primarily on nectar from flowers and small insects. Unlike many other hummingbirds, it is known for being particularly territorial and will aggressively defend feeding spots.
Fun Fact
Xantus’s Hummingbird is named after John Xantus, a 19th-century Hungarian zoologist and naturalist who contributed to early ornithology studies in North America.
2. Xavier’s Greenbul (Phyllastrephus xavieri)

Appearance and Features
Xavier’s Greenbul is a small, olive-green songbird with a slightly darker back and lighter underparts. Its nondescript coloration helps it blend seamlessly into the dense tropical forests where it lives.
Habitat and Behavior
This species is found in the tropical rainforests of Central Africa, particularly in countries like Cameroon, Gabon, and the Democratic Republic of the Congo. It forages for insects, fruit, and small invertebrates among the dense foliage.
Fun Fact
Greenbuls are part of the bulbul family, known for their melodious calls. Xavier’s Greenbul, however, is more secretive and often remains hidden in thick vegetation, making it difficult to spot.
3. Xingu Scale-backed Antbird (Willisornis vidua)

Appearance and Features
The Xingu Scale-backed Antbird is a stunning species with dark plumage and intricate white scaling across its back and wings. Males are generally darker, while females have slightly lighter brownish tones.
Habitat and Behavior
This bird is endemic to the Xingu River Basin in Brazil, residing in lowland rainforests. Like other antbirds, it follows army ant swarms to snatch up fleeing insects. It has adapted to a highly specialized feeding behavior, relying on the movement of ants to flush out its prey.
Fun Fact
The Xingu Scale-backed Antbird is an indicator species for the health of its rainforest habitat. Unfortunately, deforestation in the Amazon threatens its population.
4. Xinjiang Ground-Jay (Podoces biddulphi)

Appearance and Features
The Xinjiang Ground-Jay is a medium-sized bird with a mix of sandy brown and black plumage. It has a slightly curved beak and long legs, which help it navigate its harsh desert environment.
Habitat and Behavior
This rare species is found in the arid and semi-arid regions of Xinjiang, China, particularly in rocky deserts and scrublands. Unlike many other jays, it spends much of its time on the ground, using its powerful legs to forage for seeds, insects, and small reptiles.
Fun Fact
Despite being in the jay family (Corvidae), which includes crows and magpies, the Xinjiang Ground-Jay is one of the least social members of the group, often foraging alone or in pairs.
5. Xolmis (Genus of Tyrant Flycatchers)

Overview
The Xolmis genus consists of a group of flycatchers found in South America. Some notable species within this genus include:
- White Monjita (Xolmis irupero)
- Black-and-white Monjita (Xolmis dominicanus)
- Gray Monjita (Xolmis cinereus)
Appearance and Features
Birds in the Xolmis genus typically have a stout body, a sharp beak, and a strong flight. Their coloration varies, but many species have a monochromatic black-and-white or grayish appearance.
Habitat and Behavior
These birds thrive in grasslands, shrublands, and open areas, where they hunt for insects mid-air. Their aggressive hunting style and swift movements make them excellent aerial predators.
Fun Fact
Xolmis flycatchers are known for their distinct perching habits. They often sit on high vantage points, scanning the ground for potential prey before making rapid dives to catch insects.
Faqs
Which of these birds is the rarest?
The Xinjiang Ground-Jay is considered one of the rarest due to its restricted range and habitat loss.
Are there any conservation efforts for these birds?
Yes, conservation programs are in place for the Xingu Scale-backed Antbird and Xinjiang Ground-Jay due to habitat destruction.
Do any of these birds migrate?
Most are non-migratory, but some Xolmis species may move seasonally depending on food availability.
Which of these birds is easiest to spot in the wild?
Xantus’s Hummingbird is relatively easier to spot in Baja California compared to the others.
What do these birds eat besides insects and nectar?
Some, like the Xinjiang Ground-Jay, also consume seeds and small reptiles.
