Quick verdict
Start with the direct answer, then use the structured comparison below to see what changes the outcome.
The Dwarf Cassowary wins, and it isn't close. Casuarius bennetti is a flightless rainforest heavyweight of New Guinea. It stands about 1 m tall, weighs roughly 18–26 kg, and carries dagger-like inner toe claws behind a forward kick that can split skin and bruise bone. The Sri Lanka Frogmouth is a small nocturnal bird of about 23 cm and well under 100 g. It is built for stillness, camouflage and snapping up insects, not for combat. It has no talons for grappling, no hooked killing beak and no mass to absorb a strike. The frogmouth's real weapon is never being noticed, and its real escape is a short, silent flight. In any frame where the two actually make contact, the cassowary's mass and kick end the exchange immediately.
Read the full explanation
Dwarf Cassowary wins: it weighs roughly 200–300 times more than the frogmouth.
The cassowary's dagger-clawed kick is a true defensive weapon. The frogmouth has none.
The frogmouth survives by camouflage and flight, not by fighting.
The only 'win' open to the frogmouth is not being found.

Editorial note
Why people disagree
'Flight beats flightless': being able to fly helps the frogmouth escape, but it doesn't help it win a confrontation.
Explosive power
Fights between birds are decided by legs and claws. The cassowary carries a built-in blade. The frogmouth's feet are for gripping branches.
Close-range durability
A single strike can't meaningfully hurt the cassowary, while one hit from the cassowary would overwhelm the frogmouth.
Concealment craft
The frogmouth is one of Asia's finest stillness specialists, and being overlooked is its whole survival plan.
Read the full explanation +
'Camouflage is underrated': true for survival. But going undetected means avoiding a fight, not beating an opponent.
'Cassowaries aren't predators': correct. They are fruit-eaters that also take small animals opportunistically. But their defensive kick is famously dangerous, and that is what decides a contact fight.
Comparison FAQ
Short, direct answers to the next questions readers usually ask after the headline verdict.
Would a dwarf cassowary beat a Sri Lanka frogmouth in a fight?+
Yes, overwhelmingly. The cassowary is hundreds of times heavier and has clawed, kicking feet. The frogmouth has no meaningful weapons.
Which bird is stronger?+
The dwarf cassowary, by an enormous margin. Its legs are built for powerful running and kicking, while the frogmouth's feet are built for perching.
Can the frogmouth escape a cassowary?+
Usually, yes. It can fly up into the trees, which a flightless cassowary cannot do. Escaping is its real defense.
Why is the Sri Lanka frogmouth still dangerous or impressive?+
Its threat lies in survival, not force. Its bark-like camouflage and startling wide-mouth gape display help it avoid or deter many predators. It is also an efficient night hunter of insects.
Are dwarf cassowaries dangerous to humans?+
They can be. Like all cassowaries, they may kick when cornered or provoked. Give them space in the wild.

Cassowary dominates on contact.
At ground level, in tight cover, the frogmouth has no room to fly and no weapon to resist. The cassowary's forward kick and trampling mass end the exchange instantly. Mass and leg power decide fights between birds, and here the size gap is overwhelming.

Final take
The Dwarf Cassowary is the clear winner. It brings mass, armor-like plumage and one of the most dangerous kicks in the bird world. The Sri Lanka Frogmouth brings none of those things.

The frogmouth isn't a failure, though. It is a master of a different game: being invisible. It excels at surviving the night, but in any real confrontation it has no tools to fight with.

Dwarf Cassowary vs Wilson's Bird-of-paradise: Who Actually Wins?
The Dwarf Cassowary wins, and it isn't close. Casuarius bennetti stands about a meter tall, weighs roughly 17–26 kg, and carries a dagger-like inner toe claw driven by powerful running legs. Wilson's Bird-of-paradise is a jewel-sized songbird of about 16 cm and around 50–60 grams, a few hundred times lighter. In any forced close-range contact, a single cassowary kick or stomp ends the contest. The bird-of-paradise's only real 'win condition' is not winning at all. It can fly away, and it will almost always do exactly that. As a battle question, though, mass, armor-like plumage, and a lethal weapon all point one direction.
