Eurasian Eagle Owl vs Long-eared Owl

In short

The Eurasian Eagle Owl (Bubo bubo) is a massive owl with prominent ear tufts and striking orange eyes, while the Long-eared Owl (Asio otus) is smaller, with slimmer proportions and more subtle ear tufts. Both species have similar mottled plumage, but their size and behavior are key differentiators.

Identification tips

1. Size and Structure: Look for the much larger size and bulkier build of the Eurasian Eagle Owl. 2. Ear Tufts: Both have ear tufts, but the Eagle Owl's are more prominent. 3. Eye Color: Note the striking orange eyes of the Eurasian Eagle Owl compared to the yellow-orange eyes of the Long-eared Owl. 4. Behavior: Observe solitary versus communal roosting habits. 5. Vocalization: Listen for the deeper hoot of the Eurasian Eagle Owl.

Size

The Eurasian Eagle Owl is significantly larger, with a wingspan of up to 188 cm, compared to the Long-eared Owl's maximum wingspan of about 100 cm.

Plumage

Both species have mottled brown and buff plumage, but the Eurasian Eagle Owl has more pronounced barring and a paler facial disk, whereas the Long-eared Owl's facial disk is more defined with a darker border.

Behaviour

Eurasian Eagle Owls are solitary and territorial, often seen perched on rocky outcrops or large trees. Long-eared Owls, however, are more social outside the breeding season, often roosting communally in dense vegetation.

Habitat

Eurasian Eagle Owls inhabit a wide range of habitats, including forests, mountains, and semi-deserts, while Long-eared Owls prefer dense woodlands for roosting but hunt in open areas like grasslands and fields.

Voice

The Eurasian Eagle Owl has a deep, resonant hoot, while the Long-eared Owl's call is a softer, more repetitive hoot. Both species vocalize primarily at night.
