Kittlitz's Murrelet vs Marbled Murrelet

In short

Kittlitz's Murrelet and Marbled Murrelet are both small seabirds of the Brachyramphus genus, but they differ notably in their nesting habitats and some plumage details. Kittlitz's Murrelet typically nests on scree fields and open tundra, while Marbled Murrelet nests in trees of coastal forests. In the field, pay attention to their habitat and subtle plumage differences.

Identification tips

1. Habitat: Check the surrounding environment; Kittlitz's prefers glacial areas while Marbled is linked to coastal forests. 2. Plumage: Look for the paler, mottled plumage of Kittlitz's versus the darker, more uniform Marbled. 3. Nesting Behavior: If observed nesting, Kittlitz's will be on the ground, Marbled in trees. 4. Location: Consider geographic range and typical nesting sites when identifying.

Size

Both species are similar in size, typical of small alcids.

Plumage

Kittlitz's Murrelet has a paler, more mottled appearance with a lighter face and underparts, especially during the breeding season. Marbled Murrelet tends to have a darker, more uniform appearance with a less distinct face pattern.

Behaviour

Both species are elusive and secretive, but Marbled Murrelet is known for its unique tree-nesting behavior, unlike the ground-nesting Kittlitz's Murrelet.

Habitat

Kittlitz's Murrelet is often found near tidewater glaciers and glacial streams, nesting in scree fields and tundra. Marbled Murrelet prefers coastal, older forests for nesting, often far from the sea.

Voice

Vocalizations are not a primary distinguishing feature in the field, and both species can be difficult to hear over the sound of the ocean.
