Visual Identification

Appearance

The Flammulated Owl is a small, compact owl with large dark eyes and small ear tufts. Its plumage is primarily mottled grey and brown, providing excellent camouflage against tree bark. The owl's name comes from the flame-like markings on its face.

Two different color types of Flammulated Owls exist, with grayish coloring prominent in the northwestern Great Basin Range and a reddish variation further to the southeastern part of their range.

Both sexes look similar, with subtle variations in coloration. Females, however, are marginally larger and heavier than males.

Juveniles are similar to adults. They are mostly barred with gray and dusky markings, with dull rusty gray or grayish-white streaked underparts.

Distribution

Flammulated Owls inhabit montane forests dominated by pine, fir, and aspen trees across western North America. Their range extends from British Columbia to Mexico, and they prefer open, mature forests at higher elevations.

These owls are migratory, spending summers in the northern parts of their range and winters in Mexico and Central America. During the breeding season, they are most commonly found in the Rocky Mountains and Pacific Northwest in the United States.

Distribution Map

This map gives you a rough idea of where you might spot a Flammulated Owl. The coloured areas show countries where these birds have been seen.

A few things to keep in mind:

  • Birds might not be everywhere in the coloured areas, for example, they may be present around the coast of that country
  • Where birds live can change with seasons and available food
  • This map is quite simple - it doesn't show exact locations

We're working on making our maps even better! Soon, we hope to show you:

  • More detailed maps for bigger countries, including state and region
  • How birds move around during different seasons

Bird Attributes Explained

Our bird attributes system rates various aspects of a bird's capabilities on a scale of 0-100, based on data from field observations, scientific studies, and expert knowledge.

Attribute Categories:
  • Agility: Manoeuvrability, speed, and grace in flight or movement.
  • Strength: Physical power, often correlating with size and hunting abilities.
  • Adaptability: Ability to thrive in various environments or changing conditions.
  • Aggressiveness: Territorial behaviour and assertiveness, particularly during breeding seasons.
  • Endurance: Stamina, often seen in migration patterns or foraging behaviours.

Understanding the Ratings:

  • 0-20: Very Low
  • 21-40: Low
  • 41-60: Average
  • 61-80: High
  • 81-100: Very High

Remember, these attributes are relative to other bird species and don't necessarily indicate superiority.

Agility 85

Agility

Reflects the bird's manoeuvrability, speed, and grace in flight or movement.

The Flammulated Owl demonstrates remarkable agility, being capable of manoeuvring through dense forest canopies to catch insects in flight. Their small size and adaptations for nocturnal hunting in complex environments suggest high agility.

Strength 20

Strength

Indicates the bird's physical power, often correlating with size and hunting abilities.

As one of the smallest owls in North America, the Flammulated Owl has limited physical strength. Their diet consists primarily of insects, indicating they are not built for overpowering large prey or carrying heavy loads.

Adaptability 75

Adaptability

Represents the bird's ability to thrive in various environments or changing conditions.

These owls show good adaptability, inhabiting various montane forests across a wide range from British Columbia to Mexico. Their ability to migrate long distances and survive in different elevations (1,500 to 3,000 metres) demonstrates considerable adaptability.

Aggressiveness 30

Aggressiveness

Measures the bird's territorial behaviour and assertiveness, particularly during breeding seasons.

Flammulated Owls are described as secretive and are not known for aggressive behaviour. Their primary defence seems to be camouflage rather than confrontation. However, they may display some aggression when defending nests or territories during breeding season.

Endurance 70

Endurance

Reflects the bird's stamina, often seen in migration patterns or foraging behaviours.

The Flammulated Owl's ability to migrate up to 5,000 kilometres annually suggests significant endurance. Their nocturnal lifestyle, involving hours of active hunting each night, also indicates good stamina. However, their small size may limit overall endurance compared to larger bird species.

Diet

Flammulated Owls are insectivores, primarily feeding on moths, beetles, grasshoppers and crickets. They hunt by perching on branches and swooping down to catch prey in flight or on vegetation. During the breeding season, they may occasionally take small vertebrates to feed their young.

Larger prey may also be eaten occasionally, including small voles, mice, and songbirds, although insects and invertebrates are the largest element of their food intake.

Behaviour

Flammulated Owls are nocturnal and highly secretive, making them challenging to observe. They are agile flyers, capable of maneuvering through dense forest canopies to catch insects.

During the day, these owls roost close to tree trunks, relying on their cryptic coloration for concealment.

Vocalisation

The Flammulated Owl's call is a distinctive, low-pitched 'boop' or 'poot' sound, repeated at intervals. This vocalization is much lower than expected for such a small owl, often causing listeners to mistake it for a larger species. During courtship, males may produce a soft trill.

Nesting & Breeding

Breeding season for Flammulated Owls typically begins in late spring. Males attract females with their distinctive low-pitched hoots, and pairs form monogamous bonds for the breeding season.

These owls are cavity nesters, utilizing abandoned woodpecker holes or natural tree cavities. They do not add nesting material. Females typically lay 2-4 white eggs per clutch.

Incubation lasts about 23 days, and it is primarily done by the female. Nestlings fledge after about 25-27 days but remain dependent on their parents for several weeks.

Conservation and Status

Global Conservation Status

Least Concern [1]

While currently listed as Least Concern, Flammulated Owls face threats from habitat loss due to logging and forest management practices. Climate change may also impact their distribution and prey availability. Conservation efforts focus on maintaining mature forest habitats and promoting sustainable forestry practices.

Population Data

Global Population Estimate

12,000 mature individuals [2]

Global Population Trend

Trend data may be uncertain or fluctuating

Birdwatching Tips

  • Listen for their low-pitched, ventriloquial hoots at night during the breeding season
  • Search for them in mature pine or fir forests at higher elevations
  • Look for small, motionless shapes against tree trunks during the day
  • Use playback sparingly and responsibly to attract them

Additional Information

Quick Facts

Other names:

Flammulated Screech Owl

Family:

Strigidae

Average Lifespan

7 to 10 years

Predators

Did You Know?

  1. Flammulated Owls have asymmetrical ear openings, which helps them locate prey by sound.
  2. They are one of the smallest owls in North America, barely larger than a sparrow.
  3. Despite their small size, they can migrate up to 5,000 kilometres annually.
