Lophotriccus pileatus, commonly known as the Scale-crested Pygmy Tyrant, is a small bird found in subtropical and tropical moist lowland forests of Central and South America. Recognizable by its distinctive scale-like crest, this tiny flycatcher is known for its agile movements and high-pitched calls as it hunts insects.

Lophotriccus pileatus, commonly known as the Scale-crested Pygmy Tyrant, is native to the tropical regions of Central and South America. Its geographical distribution extends from Honduras in Central America, through Nicaragua, Costa Rica, Panama, and into South America, covering regions in Colombia, Venezuela, Ecuador, Peru, and Bolivia.

The Scale-crested Pygmy Tyrant typically inhabits subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. The environmental conditions in these areas are generally characterized by high humidity, consistent rainfall, and temperatures that range from warm to hot, with dense forest canopy and rich undergrowth.

This species occupies an ecological niche as a small insectivore, often found foraging in the lower and mid-levels of the forest canopy. It is well-adapted to life in dense forested areas, where it uses its small size and agility to navigate through the foliage in search of insects and other small arthropods.
