A Streak-throated hummingbird found in northern South America from west to eastern Columbia. Like other hermits, it has a dark mask bordered by buff stripes and a long bill. The faint black lines on its throat and breast help distinguish it from other similar species. These lines are variable, and on adult males, they form an almost solid black spot, but females and young birds may show only a few small spots. Found in a variety of habitats including seasonally flooded rainforests along the Amazon and dry and clearing forests in the highlands. Uncommon to rare throughout most of its range.

The hermit will aggressively defend flower clusters and feeding areas from other hummingbirds.

The streak-throated hermit hummingbird is somewhat solitary and territorial. Males establish feeding territories, usually centered around particularly nectar-producing plants. They chase other hummingbirds that try to feed in their territory, even the extra streak-throated hermit. On the other hand, women do not have fixed territories. They can visit and exploit flowers in a wide area that is dominated by multiple male territories.
