A key field mark of this species is the streak of reddish feathers along the shoulder and onto the back. Flammulated owls have a raptorial toe configuration. There is no sexual dimorphism between the sexes. Food Habits Otus flammeolus are insectivores. They feed on insects, moths, beetles, and crickets.
Flammulated owls are predators that sit on a perch and pounce on their prey.
Reproduction Flammulated owls are cavity nesters. Most nest sites are in woodpecker holes or natural tree cavities. They lay their eggs from about mid-April through the beginning of July. Generally 1-5 eggs are laid, depending on the variations in the weather. The eggs are incubated for 21 to 24 days, and can hatch anywhere from early June to the end of July.
