the frogmouth differs from its cousin by heavier bills, shorter and more rounded wings and upright posture when perched.

Female is more uniformly rufous, with irregular black-tipped white spots on the upper mantle, scapular and underparts.

[3] They have a thick large bill that takes the most part of their face and make them look like an angry old man.

The most popular hypothesis is that the bird would use them to detect insects and know when to close their bill shut on the invertebrates when this one is near the mouth.

[4] The Asian bird possesses short round wings and tail which explain its very local territory.

[3] There are two recognized subspecies of Hodgson's frogmouth: The species arboreal is an adept of broad leaves evergreen or mixed coniferous tropical rain forests[5] inside of which it will be found mainly on the middle and lower storeys.

[4][5][7] The first Hodgson's frogmouth in central Laos was recorded in 1994 during the month of April in a dry evergreen forest at 1000 m of altitude.

[6] The nocturnal active bird catches prey on short flights from its perches using shrike-like or roller-like hunting method.

This bird benefits from the resemblance of its plumage to bark, and is easily confused with a part of the tree by predators.

In case of a predator hanging too close, it developed a technique that could be called the "broken branch": the small bird freezes sitting on its nest and its partner and points its bill upward making one with the tree.

Males incubate in daytime that's why they have duller colors than females which are more active in nocturnal territory defense.

Hodgson's frogmouths are observable also in Annam during the period before reproduction in late February or early March.

[1] Even though the population size has not been quantified, it is not believed to approach the criterion of a decline greater than 30% over ten years or three generations to be considered vulnerable.
