Tropical Royal Flycatcher

Onychorhynchus coronatus

In Spanish: Mosquero Real Tropical

  • Resident

A quiet streamside flycatcher that hides a fan-shaped crest.

Most Tropical Royal Flycatchers look like a plain brown bird sitting very still over a forest stream. The fan-shaped crest is rarely raised, so seeing it open is the prize.

In Costa Rica it is uncommon to rare, found in the lowlands of both slopes. Finding one takes patience and some luck, and the best places to start are shaded streams and rivers in humid forest.

On a trip we build around this bird, slow mornings in lowland forest with a local guide serve you better than a quick stop.

How to find it

Check shaded spots along forest streams and rivers, and scan horizontal branches for a solitary bird sitting still. It is scarce in Costa Rica, so finding one takes patience and some luck, and a local park guide can help. It feeds more often just before and after rain, so damp spells by a stream are worth your time. Guided photo trips visit active nests in forest, where visitors wait quietly for the birds to return. These outings are built around patience rather than a quick sighting.

How to recognise it

Think of a plain brown flycatcher with a long tail, a broad flat bill and buff underparts. It measures about 12.5 to 18 cm.

The marks to check:

- a broken buffy eye ring

- a whitish throat

- a warm buff belly

- a cinnamon-rufous rump and tail

The rufous tail and rump are the best marks to look for.

The famous crest is fan-shaped, red in males and yellow-orange in females, with blue and black tips. It is rarely raised, so most birds look plain brown. With the crest folded, the head has a hammerhead look that helps pick it out from other brown forest flycatchers.

Behaviour and diet

It perches and makes short flights to catch flying insects, and its diet is mostly insects and other small invertebrates. Look for a solitary bird sitting still on a horizontal branch about 2 to 5 m up.

The nest is long and narrow and hangs from a branch or vine, usually over water. The clutch is two eggs. In the nesting season the birds spend more time near their nests, which gives the best chance of seeing the crest display.

Where it lives

It lives in humid lowland forest, both mature and second growth, staying in the lower and middle levels, often beside streams. In Costa Rica it is most common below 600 m and occasionally reaches 1,200 m in suitable habitat.

On the Pacific side it occurs in the lowlands up to 750 m, and after breeding it may move up to 900 m. It is uncommon to fairly common there. On the Caribbean side it stays below 400 m, in the lowlands northwest and east of the Río Frío area, and is rare and local elsewhere.

When to see it

One site says the best chances come from February to May, when birds are more active and vocal, with early morning, 6 to 9 am, as the peak time. A photo tour company calls April one of the best months, as nesting birds stay nearer their nests.

Similar birds

With the crest folded, it looks like a plain brown flycatcher with a long tail, a broad flat bill and buff underparts. Check the rufous tail and rump first. The hammerhead shape of the folded crest also helps separate it from other brown forest flycatchers.

Names and lore in Costa Rica

Mosquero real is the Spanish name used in both Mexico and Costa Rica, and the AOCR list gives Mosquero Real Tropical. Other countries use different names, such as cazamoscas real in Honduras.

Status and conservation

The AOCR lists it as a resident (R), described in Costa Rica as uncommon to rare, with habitat loss and low population density cited as concerns.

Photography tips

A Boca Tapada tour operator advises a 400 to 600 mm lens and a fast shutter, 1/800 s or quicker. The understory is dark, so high ISO is normal. Get down to the bird's eye level.

The crest is more likely to open when males confront each other, during courtship, or when the bird is startled. Waiting at a known perch tree, sometimes one to two hours, is the most reliable method.
