Costa Rican Pygmy-Owl

How to find it

Look for agitated small birds. Fiery-throated Hummingbirds are a common sign, and tour guides report seeing the owl this way at several high-elevation sites. A birder at La Georgina followed two upset Fiery-throated Hummingbirds to one and found another on Irazu the same way. On Irazu a Sooty Robin was diving at a fence post where an owl sat. Listen early in the morning and late in the afternoon, and scan forest edges and pastures with scattered trees. Look high too: one sat beside a bromeliad around midday on the road up to Cerro de la Muerte.

How to recognise it

This is a tiny owl, roughly 14.5 to 17 cm long, with a rounded head and no ear tufts.

It comes in two color forms: one mostly brown, one rufous.

The breast and belly are white.

The tail has four white bands.

The nape carries two blackish spots with pale edges that look like eyes. These false eyes may confuse predators that approach from behind.

On the crown, look for small white spots, and for bars on the flanks.

In Costa Rica it is the darkest pygmy-owl, with the boldest pattern and a distinct rufous color form.

Behaviour and diet

This owl is solitary and mostly nocturnal, but it is also partly active by day, and that daytime activity is why small birds so often give it away. Like other pygmy-owls, it swishes its tail from side to side when agitated.

Its diet is poorly known in general, though it probably eats many arthropods and small vertebrates, judging by other pygmy-owls. It stays in the same place all year and does not migrate.

Where it lives

In Costa Rica it lives at about 900 to 3,000 m on the Caribbean slope and about 1,200 to 3,000 m on the Pacific slope. It ranges from the tree line down to those lower limits in the middle and high parts of the Central Volcanic and Talamanca ranges.

It favors the canopy and edges of humid montane oak and evergreen forest, and also uses partly cleared areas such as pastures with scattered trees.

Similar birds

Two other pygmy-owls occur in Costa Rica, Ferruginous and Central American, but this one lives at higher elevations than both, so elevation is a good first clue. It prefers wetter, more forested areas than the Ferruginous Pygmy-Owl, and it usually has much more conspicuous spotting.

Names and lore in Costa Rica

Costa Ricans call it Mochuelo Montañero. Other Spanish names in use are Mochuelo Costarricense and Mochuelo Costaricense.

Status and conservation

It is a resident endemic on the AOCR list (R-END), rated Least Concern, and rare to locally fairly common in Costa Rica and rare in Panama.

Photography tips

Daylight mobbing is your friend: follow the scolding birds and you may find the owl sitting still. One was seen high in a tree beside a bromeliad around midday on the road up to Cerro de la Muerte, and another sat on a fence post on Irazu.
