Quick verdict
Start with the direct answer, then use the structured comparison below to see what changes the outcome.
The Emerald Toucanet wins. These two Neotropical birds are close in size, but their bodies are built for opposite jobs. The toucanet is a daytime forager and an opportunistic nest raider. It carries a stout, serrated bill, moves with quick hopping agility, and has the temperament of a bird that routinely pushes into other species' nests for eggs and chicks. The Common Potoo is a nocturnal flycatcher. Its tiny bill sits over an enormous soft gape, and its weak, short feet are made for perching rather than grappling. Its entire survival strategy is to become a broken branch and never be noticed. Once the two birds actually meet in daylight, the potoo has almost no offensive weapon beyond a startling gape display, while the toucanet has a pincer and the willingness to use it. The potoo's real wins come from never being found and from owning the night. They do not come from fighting.
Read the full explanation
Emerald Toucanet wins a direct confrontation, thanks to its serrated bill, daytime aggression and greater agility.
Common Potoo is slightly larger in wingspan, but its soft, wide mouth and weak feet are not fighting tools.
Potoo 'wins' only by avoidance: its stump camouflage and nocturnal schedule mean the toucanet often never sees it.
The toucanet's nest-raiding habit makes it the more practiced aggressor.

Editorial note
Why people disagree
The potoo's gaping red-eyed defense display looks fearsome in photos, but it is a bluff aimed at predators, not a weapon.
Bill weaponry
The toucanet's bill can grip, jab and tear. The potoo's mouth is a net for catching moths, not a tool for injuring rivals.
Branch agility
Reach and repositioning decide who lands the first strike. The toucanet controls the angle.
Ambush-proof concealment
The potoo's best defense is being mistaken for wood, which can stop an encounter from ever starting.
Read the full explanation +
Some readers count camouflage as a win. Being unfindable is survival, not victory in a contest.
The two species keep almost opposite schedules, so a 'fair' meeting is hard to define. That shifts the outcome depending on whether it happens at dawn, noon or midnight.
Comparison FAQ
Short, direct answers to the next questions readers usually ask after the headline verdict.
Would a Common Potoo beat an Emerald Toucanet?+
Not in a direct fight. The toucanet's bill and aggression give it a clear advantage. The potoo survives by hiding, not by fighting.
Which bird is stronger?+
The Emerald Toucanet is the more effective combatant. The potoo may appear larger because of its long wings and fluffy plumage, but the toucanet's dense build and powerful bill make it functionally stronger in a clash.
Why is the potoo still dangerous to encounter?+
Its sudden gaping display, with an enormous mouth and wide eyes, can startle attackers into hesitating. Its camouflage is also so good that most predators never locate it at all.
Do toucanets really attack other birds?+
Emerald Toucanets are known to raid the nests of other birds for eggs and nestlings, alongside their mostly fruit-based diet.
Would the outcome change at night?+
Yes. The potoo is nocturnal and the toucanet roosts at night, so a night encounter favors the potoo.

Common Potoo
Verdict confidence
82%
The potoo wins by never being found.
Pressed upright on a broken snag with its eyes slit, the potoo reads as dead wood. The toucanet's foraging search image is tuned to fruit, nests and movement, so it likely passes by. No contest occurs, and survival goes to the potoo.

Final take
The Emerald Toucanet is the overall winner because it carries the only real weapon in this matchup and has the temperament to use it. Its serrated bill and quick canopy movement turn any daylight meeting into a one-sided exchange.
Read the full explanation
The Common Potoo is not a fighter, and it was never meant to be. Its genius is subtraction: removing itself from the visual world by day and from the competition entirely at night. That makes it extraordinarily hard to beat if 'winning' means surviving, but it loses whenever the contest is forced.

Andean Cock-of-the-rock vs Emerald Toucanet: Who Actually Wins?
The Andean Cock-of-the-rock wins, though not by much. A displaying male typically weighs about 200–300 g. Most Emerald Toucanets weigh roughly 150–230 g. That extra mass sits in a compact, deep-chested body built for explosive wingbeats inside steep river gorges, so the cock-of-the-rock can shove, buffet and outlast a rival in any close scramble. The Emerald Toucanet carries the more dangerous-looking tool: a long, serrated bill that gives it reach and that it uses to raid other birds' nests. That bill is light and honeycombed, though. It is excellent for plucking fruit and snatching eggs, but it is not a reinforced weapon. The toucanet is also slightly more agile and somewhat more opportunistic, and it can win brief harassment exchanges, especially near its own nest cavity. Over a sustained, body-to-body contest, the heavier bird with the stronger frame usually prevails.

Emerald Toucanet vs Sword-billed Hummingbird: Who Actually Wins?
The Emerald Toucanet wins clearly. It weighs roughly 150–230 g against the Sword-billed Hummingbird's 12–15 g, more than ten times heavier. Its serrated, gripping bill is built to seize and crush fruit, insects, small lizards, and the eggs and nestlings of other birds. The hummingbird's famous bill can be about 10 cm long, longer than its body without the tail, but it is a hollow-feeling nectar probe, not a weapon. It is light and slender, and the bird has to hold it upward when perched just to stay balanced. In any physical clash the toucanet's mass, bite force and predatory habits decide things fast. The hummingbird's real advantage is aerial control. It can hover, reverse and dart away, which means it usually escapes rather than wins.
