Bird-eating spiders are some of the largest and most fascinating arachnids on the planet. Though they rarely hunt birds, their size, power, and hunting abilities make them capable of taking down small vertebrates. Found across South America, Africa, and Asia, each species has unique traits—from vibrant colors to aggressive defenses. In this guide, we’ll explore 10 notable types of bird-eating spiders, their habitats, behaviors, and how to identify them.
1. Goliath Birdeater (Theraphosa blondi)
The Goliath birdeater is the largest spider in the world by mass and size. Native to the rainforests of northern South America, this spider is famous for its intimidating size, dense body hair, and defensive hissing sound. Despite its name, it rarely preys on birds, preferring insects, worms, and small vertebrates.
Identification
- Thick, hairy body with a leg span of up to 11 inches (28 cm)
- Color varies from dark brown to reddish-brown
- Prominent fangs that can reach up to 1.5 inches
- Abdomen covered in dense urticating hairs
- Eyes small and clustered on the top front of the cephalothorax
Habitat and Distribution
The Goliath birdeater is found in the Amazon rainforest regions of Venezuela, Brazil, Guyana, and Suriname. It prefers humid, tropical lowland forests and lives in deep burrows in the forest floor, which it lines with silk.
Diet and Hunting Behavior
Although it’s called a “birdeater,” it mostly feeds on earthworms, frogs, small snakes, and insects. It is a nocturnal ambush predator, waiting silently at the burrow entrance and striking quickly with its fangs. The venom liquefies the prey’s insides for easy consumption.
Defense Mechanisms
When threatened, the Goliath birdeater can:
- Rub its legs together to produce a hissing noise (stridulation)
- Flick urticating hairs from its abdomen, which can irritate skin and eyes
- Rear up to expose its large fangs as a warning display
Reproduction and Lifespan
Mating usually occurs during the rainy season. After mating, the female may eat the male. She lays up to 200 eggs in a silk egg sac, which she guards aggressively. Males live for about 3–6 years, while females can live over 15 years in captivity or the wild.
2. Salmon Pink Birdeater (Lasiodora parahybana)
The Salmon Pink Birdeater is one of the largest tarantulas in the world by leg span, second only to the Goliath birdeater. Native to northeastern Brazil, this species is known for its fast growth, striking pink hairs, and docile temperament in captivity. Though large enough to eat small birds, its diet mainly consists of insects and small vertebrates.
Identification
- Leg span can reach up to 10 inches (25 cm)
- Dark brown to black body with distinct salmon-pink hairs on the legs and abdomen
- Thick, robust body with a slightly flattened cephalothorax
- Prominent fangs and visible spinnerets
- Dense leg hair gives it a fluffy appearance
Habitat and Distribution
This species is native to the Atlantic forest region of Paraíba, Brazil. It prefers humid environments and tends to burrow in soft soil, often hiding under logs, rocks, or vegetation. Its natural range is limited, but it’s widely bred in captivity.
Diet and Hunting Behavior
The Salmon Pink Birdeater primarily feeds on crickets, roaches, small amphibians, and mice. It relies on ambush hunting, detecting vibrations and lunging at prey with speed and precision. Its venom is potent for subduing prey but generally harmless to humans.
Defense Mechanisms
When disturbed, it may:
- Kick urticating hairs as a first line of defense
- Raise its front legs to appear more threatening
- Retreat quickly into its burrow if space allows
- Bite if provoked, though it’s usually reluctant to do so
Reproduction and Lifespan
Females lay up to 1,000 eggs per clutch and aggressively guard the egg sac. Spiderlings grow rapidly, reaching maturity in just a few years. Females live 10–15 years, while males typically die within 3–5 years after maturity.
3. Chilean Rose Hair Tarantula (Grammostola rosea)
The Chilean Rose Hair Tarantula is one of the most well-known pet tarantulas due to its gentle temperament and adaptability to dry environments. Native to Chile’s desert regions, this spider is smaller than other bird-eating species but still large enough to prey on small animals.
Identification
- Leg span ranges from 4.5 to 6 inches (11–15 cm)
- Color varies: rose-colored, brown, or gray with pink sheen
- Covered in short, fine hairs
- Stocky build with a rounded abdomen
- Less hairy legs compared to rainforest species
Habitat and Distribution
This species is native to the Atacama Desert region of Chile and can tolerate arid conditions. It lives in burrows dug into the ground, lined with silk for moisture retention and structure. Occasionally found in scrublands and rocky crevices.
Diet and Hunting Behavior
In the wild, it hunts insects, small reptiles, and sometimes baby rodents. It is a slow but deliberate predator, relying on stealth and vibration sensing to capture prey. In captivity, it’s commonly fed crickets, mealworms, and roaches.
Defense Mechanisms
Its defenses include:
- Kicking urticating hairs, though rarely aggressive
- Retreating to safety rather than fighting
- Producing a mild venom that’s harmless to most humans
- Freezing motionless when threatened (a passive defense)
Reproduction and Lifespan
Females can lay up to 500 eggs per sac. Spiderlings are slow growers. Females live up to 20 years, while males live 4–6 years. Mating should be supervised in captivity as females may attack the males post-copulation.

FAQs
1. Do bird-eating spiders actually eat birds?
Yes, but rarely. While they’re capable of killing small birds, their typical diet includes insects, frogs, lizards, and small rodents. The name “bird-eating spider” comes from a historical observation, not a regular feeding habit.
2. Are bird-eating spiders dangerous to humans?
Not fatally. Most bird-eating spiders have venom that is mild to humans. Bites can cause pain, swelling, and irritation, but they’re not deadly. However, some species are highly defensive and may bite if provoked.
3. What is the largest bird-eating spider?
The Goliath birdeater (Theraphosa blondi) holds the record as the largest spider in the world by mass and body size. It can weigh over 170 grams and have a leg span up to 11 inches.
4. Do all bird-eating spiders spin webs?
No. Most bird-eating spiders are terrestrial or burrowing tarantulas and don’t use webs to catch prey. Instead, they ambush from burrows or silk-lined retreats. Arboreal species may spin dense silk for shelters but not webs for trapping.
5. Can you keep bird-eating spiders as pets?
Yes, many people keep them in captivity. Popular species like the Chaco Golden Knee and Salmon Pink Birdeater are common in the pet trade. However, they require proper humidity, temperature, and space, and some species can be very aggressive or fragile.
